Local SKF sales and service representatives and worldwide distributors provide access to the range of SKF bearings, maintenance
products, lubricants, condition monitoring instrumentation and software, independent of your location.
In any kind of rotating machinery, from huge rolling machines to
the smallest of motors, the bearing knows if there is a potential
problem. As the primary interface between moving parts, the bearing is literally the diagnostic heart of the machine.
Misalignment, unbalance, looseness and friction are all telegraphed through the bearing. Understanding the information coming
from this diagnostic “pulse” and then applying the latest and best
technology to the problem is the key to raising machine productivity
and lowering operating costs.
This SKF condition monitoring essentials product catalogue features a convenient collection of monitoring tools that no industrial
manufacturing plant should be without.

SKF Machine Condition Advisor
simultaneously measures
vibration signals and
temperature to indicate machine
health or bearing damage.
Multiple measurements with a single device
The SKF Machine Condition Advisor provides an overall “velocity”
vibration reading that measures vibration signals from the machine
and automatically compares them to pre-programmed International
Organization for Standardization (ISO) guidelines. An “Alert” or “Danger” alarm displays when measurements exceed those guidelines.
Simultaneously an “enveloped acceleration” measurement is taken
and compared to established bearing vibration guidelines to verify
conformity or indicate potential bearing damage.
The SKF Machine Condition Advisor also measures temperature
using an infrared sensor to indicate uncharacteristic heat.
Accuracy, flexibility and confidence
When performing measurements, the SKF Machine Condition Advisor’s acceleration sensor input signal is processed to produce two
different measurements for each POINT on the machinery – overall
velocity and enveloped acceleration.
SKF Machine Condition Advisor CMAS 100-SL
At the same time, the SKF Machine Condition Advisor’s non-contact
infrared sensor measures the surface temperature of the measurement location and simultaneously displays all three measurement
values.
Depending on the SKF Machine Condition Advisor’s System setting, the front-panel LCD simultaneously displays:
•
•
•
•
Metric or Imperial units
Velocity in mm/s RMS or in./s derived Peak
Temperature in Celsius or Fahrenheit
Acceleration enveloping readings in gE

SKF Machine Condition Advisor CMAS 100-SL
Understanding and using guidelines for
vibration
The SKF Machine Condition Advisor provides a means to evaluate
machine health based on ISO 10816-3 and to evaluate the bearings
according to general guidelines developed from a statistical analysis
of existing databases.
How to choose the correct “Alarm Velocity Group” for your
machinery
The Alarm Velocity Group (G2&4 or G1&3) determines the instrument’s “overall vibration” alarm limits. Therefore, select the Group
that best describes the general size, type, and speed of the machinery being measured. Note that these machine group classifications
are set forth in ISO 10816-3, which rates overall velocity vibration
levels for standardized machinery classifications.
Groups 2 and 4 (default)
ISO Group 2 and 4 classifications define the following type of
machinery:
• Medium-sized machines and electrical machines with a shaft
height between 160 and 315 mm (6.3 and 12.4 in.).
• These machines are normally equipped with rolling element
bearings, but may use sleeve bearings, and operate at speeds
above 600 r/min.
• These machines include pumps with multi-vane impellers and
integrated drivers.
Groups 1 and 3
ISO Group 1 and 3 classifications define the following type of
machinery:
• Large machinery and electrical machines with a shaft height
greater than 315 mm (12.4 in.).
• These machines are generally equipped with sleeve bearings, but
may use rolling element bearings.
These machines include pumps with multi-vane impellers and
integrated drivers.
Rigid or Flexible foundation?
An additional setting allows the specification (when defining the
overall alarm levels) of measurements taken from machinery with
rigid (default) or flexible foundations.
Options are:
G2 and 4R (default)
Alert: 2,8 mm/s (0.16 in./s)
Danger: 4,5 mm/s (0.25 in./s)
G2 and 4F
Alert: 4,5 mm/s (0.25 in./s)
Danger: 7,1 mm/s (0.39 in./s)
G1 and 3R
Alert: 4,5 mm/s (0.25 in./s)
Danger: 7,1 mm/s (0.39 in./s)
G1 and 3F
Alert: 7,1 mm/s (0.39 in./s)
Danger: 11,0 mm/s (0.61 in./s)
How to choose the correct “Enveloped Acceleration
Classification” for your machinery
The Enveloped Acceleration Classification (CL1, CL2 or CL3) you
specify determines the instrument’s “bearing vibration” alarm levels.
Therefore, the Enveloped Acceleration Classification that best
describes the general size and speed of the bearings being measured
should be selected.
Options are:
CL1
Bearings with a bearing bore diameter be-tween 200 and 500 mm
(7.9 and 19.7 in.) and a shaft speed below 500 r/min.
Alert: 1 gE
Danger: 2 gE
CL2 (default)
Bearings with a bearing bore diameter between 50 and 300 mm
(2.0 and 11.8 in.) and a shaft speed between 500 and 1 800 r/min.
Alert: 2 gE
Danger: 4 gE
CL3
Bearings with a bearing bore diameter be-tween 20 and 150 mm
(0.8 and 5.9 in.) and a shaft speed from 1 800 to 3 600 r/min.
Alert: 4 gE
Danger: 10 gE
Note:
As with all commonly published severity guidelines, the above provides target thresholds
for new, refurbished and recently maintained equipment.
In addition, if both lower limits of the guideline are used (for example in CL2, a 50 mm
bearing bore diameter at 500 r/min), the applicable alarm values maybe lower. Note that
bearing bore diameter is equal to shaft height.

Dual lasers provides easy aiming and defines the target area. The
target area is highlighted at all distances with two laser dot markers.
Laser 1 indicates one point of the measurement spot on one side of
the target area to be measured and Laser 2 indicates the location of
the diametrically opposed point on the other side of the measurement spot. At the focal point, where the spot size is the smallest, the
dots line up vertically, rotating as the SKF Infrared Thermometer is
moved closer or further from the target.
Description
Emissivity
The non-contact thermometer senses the thermal energy radiated
from an object with an infrared detector. When pointed at an object,
the infrared detector collects energy producing a signal that the
microprocessor translates as a reading on the backlit display. As the
trigger is squeezed, the object temperature is continuously measured by the infrared detector. This allows for fast and accurate realtime readings.
This instrument features an extended temperature range
–60 to +1 000 °C (–75 to +1 800 °F); dual laser sighting; bright large
amber back-light LCD display; Maximum, Minimum, Difference
(MAX-MIN) and “Lock” function for continuous temperature scanning; programmable High and Low audible alarms; selectable temperature units (°C or °F); low battery indicator, and adjustable emissivity for more accurate temperature measurements.
Emissivity is a term used to describe the energy-emitting characteristics of materials. Most organic materials and painted or oxidized
surfaces have an emissivity of 0,95. Inaccurate readings can result
from measuring shiny or polished metal surfaces. To compensate for
this, adjust the unit’s emissivity reading, or cover the surface to be
measured with masking tape or flat black paint (< 150 °C /300 °F).
Allow time for the tape or paint to reach the same temperature as
the material underneath it. Measure the temperature of the tape or
painted surface.

Complements your condition monitoring program
The analog SKF Inspector 400 Ultrasonic Probe is easy to use and
can detect early stages of machine problems.
This small approach to inspection can save money, energy and
time.
Features
•

•
•
Detect pressure and vacuum leaks, including compressed air
Check steam traps and valves quickly and accurately
Detect arcing, tracking and corona in electric apparatus
Test bearings, pumps, motors, compressors, etc.
Description
The SKF Inspector 400 Ultrasonic Probe senses high frequency
sounds produced by operating equipment, leaks and electrical discharges. It electronically translates these signals by a heterodyning
process, making them audible, so that a user can hear these sounds
through a headset and see them as intensity increments on a meter.
The SKF Inspector 400 Ultrasonic Probe can complement your
condition monitoring program by providing you with the following
capabilities:
Pressure/Vacuum leaks
As any gas (air, oxygen, nitrogen, etc.) passes through a leak orifice, it
generates a turbulent flow with detectable high frequency components. By scanning the test area with the SKF Inspector 400
Valve leakage
Ultrasonic Probe, a leak can be heard through the headset as a rushing sound or noted on the meter bar graph indicator. The closer the
instrument is to the leak, the louder the rushing sound and the higher the meter reading. Should ambient noise be a problem, a rubber
focusing probe may be used to narrow the instrument’s reception
field and to shield it from conflicting ultra sounds.
Valve
Valve activity such as leakage or blockage can be accurately checked
while the valve is on line. Properly seated valves are relatively quiet
while leaking valves produce a turbulent flow as the fluid moves from
the high pressure side through the leak to the low pressure side. Due
to a wide sensitivity and ultrasonic frequency, all types of valves even
in noisy environments can be accurately tested.
Valve stems
Valve stems may be quickly tested for leaks to atmosphere.
Pressure/Vacuum leaks

SKF Inspector 400 Ultrasonic Probe CMIN 400-K
Steam trap inspection
Major steam trap manufacturers have recommended ultra sound
inspection of steam traps as one of the most reliable methods available. By converting the ultrasonic elements of a working steam trap
into the audible range, the SKF Inspector 400 Ultrasonic Probe
allows users to hear through headphones and see on a meter the
exact condition of a steam trap while it is on line. Blowby, machine
gunning, oversized traps or line blockage are all easily detected.
The SKF Inspector 400 Ultrasonic Probe markedly reduces confusion from extraneous sounds or from heat transfer, even when traps
are extremely close together.
General mechanical inspection of pumps, motors, compressors,
gears and gear boxes: all types of operating equipment may be
inspected with the SKF Inspector 400 Ultrasonic Probe. Since the
SKF Inspector 400 Ultrasonic Probe works in a high frequency, short
wave environment, problems such as cavitation in pumps, compressor valve leakage, or missing gear teeth may be heard and isolated.
Reciprocating compressor valve analysis has also become successful
with the SKF Inspector 400 Ultrasonic Probe and therefore many
engine analyzer companies now offer instruments with an ultrasonic
input port.
Electrical inspection
Heat exchangers, boilers and condensers
Arcing and corona discharge emit ultra sounds at the site of emission. This electrical discharge can be located quickly by scanning the
area with the SKF Inspector 400 Ultrasonic Probe. The signal is
heard as a frying or buzzing sound in the headset. As with pressure
or vacuum leak detection, the closer the instrument is to the discharge, the more intense the signal.
Test switch gear, transformers, circuit breakers, buss bars, relays,
junction boxes, insulators and other electrical gear.
In-leakage or pressure leakage can be readily located with the SKF
Inspector 400 Ultrasonic Probe. Fittings, valves and flanges are all
easily scanned for leakage. The high frequency, short wave nature of
ultrasound allows operators to pinpoint the location of a leak in high
noise environments.
Condenser tubes and heat exchanger tubes may be tested for
leakage through two methods: vacuum and pressure.
General mechanical inspection
The tube sheet is scanned for the tell-tale rushing sound produced
as the leak draws air into the tube.
The SKF Inspector 400 Ultrasonic Probe can detect the early stage of
a machine’s mechanical malfunction. NASA research has demonstrated that ultrasound monitoring will locate potential bearing deficiencies before they are detected by the traditional heat and vibration
methods. With the SKF Inspector 400 Ultrasonic Probe, users hear
the sound quality of a bearing as well as monitor amplitude changes
on the meter. This complements other monitoring instruments and
adds to the ability to trend, troubleshoot, and confirm potential bearing problems.
General mechanical inspection is easy with the SKF Inspector 400
Ultrasonic Probe and with very little training, users can learn to test
bearings within minutes. Current vibration programs can achieve
enhanced diagnostic ability with the SKF Inspector 400 Ultrasonic
Probe.
Prevent over-lubrication with the SKF Inspector 400 Ultrasonic
Probe by simply lubricating only until the meter reaches a specified
level. Over lubrication is one of the more common causes of bearing
failure.

TMEH1, please see the following.
SKF OilCheck TMEH1
The SKF OilCheck indicates the degradation and contamination level
of oil, and detects increased mechanical wear and loss of the oil’s
lubricating properties.
• Handheld and user friendly
• Numerical readout to facilitate trending
• Shows changes in oil condition affected by:
– Water content
– Fuel contamination
– Metallic content
– Oxidation
The usual contamination found in oils is caused by oxidation and acid
build up, which occur during normal machinery operation and typically show up as a gradual increase in the oil’s “dielectric constant”
readings over a period of time. In addition, excessive wear or
mechanical failure may cause other contaminants to occur (i.e., dirt,
soot, fuel, water, antifreeze, metal particles, etc.). These contaminants also cause an increase in the oil’s dielectric constant.
The SKF OilCheck detects and measures change in an oil’s dielectric constant by comparing measurements obtained from new and
used oil samples. Measuring and trending changes to an oil’s dielectric constant level provides information that helps optimize intervals
between oil changes, and helps detect increased mechanical wear
and loss of the oil’s lubricating properties.

Water in lubricants
Water contamination may cause different problems in different
types of lubricating oil, although corrosion is always directly associated with water ingress. Whatever the equipment, water can
displace the oil at contacting surfaces, reducing the amount of
lubrication and activating surfaces which may themselves act as
catalysts for degradation of the oil. Water is an important contaminant in many lube oil systems because of its potential to
cause failure via a number of mechanisms.
Total Base Number
Total Base Number is a measure of reserve alkaline additives put
into lubricants to neutralize acids, to retard oxidation and corrosion, enhance lubricity, improve viscosity characteristic and reduce the tendency of sludge buildup. Simply put, it is a test to
measure the ability to neutralize corrosive acids that may be
formed during normal operation.
Oil formulations of additives vary drastically between oil companies, so the most important analytical parameter is the change
in base number when compared to the lubricant when new, or
when in service, to the previous sample.
Insolubles
Monitoring of combustion related debris and oxidation products
High insolubles will cause lacquer formation on hot surfaces, sticking
of piston rings, and wear of cylinder liner, and bearing surfaces.
• Detection of insolubles from diesel engine combustion products
such as fuel ash, carbon, partially oxidized fuel, oil oxidation
products, and spent lubrication additive.
• Simple and quick to use, the Insolubles Test Papers provide a

Viscosity
Viscosity is the measure of the internal
friction of a fluid. This friction becomes
apparent when a layer of fluid is made to
move in relation to another layer. The
greater the friction, the greater the
amount of force required to cause this
movement, which is called shear. Shearing
occurs whenever the fluid is physically
moved or distributed, as in pouring,
spreading, spraying, mixing, etc. Highly
viscous fluids, therefore, require more
force to move than less viscous materials.
Insolubles
Insolubles are a build up of combustion related debris and oxidation products. Contamination comes mainly from combustion
products; fuel ash, carbon and partially oxidized fuel, plus a small contribution of oil oxidation products, and spent lubricant additive.
High insolubles will also decrease the
detergent property of oil.

SKF Electric Discharge Detector Pen TKED 1
The SKF Electric Discharge Detector Pen (EDD Pen) is a simple to
use, handheld instrument that provides a unique, reliable and safe
way to detect electrical discharges in electric motor bearings.
Electrical discharges are a result of motor shaft voltages discharging to earth through the bearing, causing electrical erosion, lubricant
degradation and ultimately bearing failure.
SKF Machine Condition Advisor
Electric motors are more vulnerable to suffer electrical erosion in
bearings when controlled by a variable frequency drive. When incorporated in a predictive maintenance program, the EDD Pen can help
detect bearings that are more susceptible to failure, and can help to
significantly prevent unplanned machine downtime.
• Unique remote solution allows operation at a distance from the
motors, which protects the user from touching machinery in
motion

SKF Electric Motor Assessment kit CMAK 200-SL
Since the 1990’s, the use of variable-frequency drives (VFDs) to
control alternating current (AC) motors has become very common, as they can save energy. However, the drawback of using
VFDs is the fact that electrical motors are more vulnerable to
suffer from electrical erosion in the bearings caused by electrical
discharge currents. Electrical erosion can cause bearings to fail
very prematurely, causing motor failure and unplanned downtime.
Until now there has not been an easy, cost effective method to
detect electrical discharge currents in electric motor bearings.
Thanks to the EDD Pen, this is now possible. Operating with only
two buttons, the EDD Pen allows everybody to detect electrical
discharge currents remotely in a safe way.
Unlike other traditional methods, the electrical discharge currents can be directly detected rather than measuring the effects
in later stages when damage has already occurred.
When incorporated into a predictive maintenance program,
the EDD Pen can significantly prevent unplanned machine
downtime.

SKF Machine Condition Detector Pro IS
CMVL 3600-IS
Intrinsic Safety (IS) rated
The SKF Machine Condition Detector Pro IS
(MCD Pro IS) is a rugged, handheld analysis
tool that captures and displays temperature,
velocity and enveloped acceleration (vibration) and alarms.
The SKF MCD Pro IS is certified Intrinsically Safe (IS) for use in hazardous environments that require either a Zone I or Class I,
Division I rating.
The MCD Pro IS collects and displays
velocity, acceleration enveloping and temperature data with general
alarm capabilities.
Features
• Multi-parameter measurements
• Simple machine monitoring
• Alarm capabilities for enhanced user confidence
Go/No Go machine monitoring
The MCD Pro IS is designed to provide a straightforward approach to
machinery monitoring. The instrument’s sensor affixes to a machine
point via a SKF MARLIN QuickConnect (MQC) stud or magnetic base
for automatic collection of vibration and temperature data. Green,
yellow and red LEDs provide easy to interpret indications of machine
status, so operations or maintenance personnel can quickly identify
the need for more in-depth analysis on a particular machine.
Multi-parameter monitoring capabilities
The MCD Pro IS operates as a stand-alone device or as an integral
component of the complete SKF MARLIN System.
By pairing the MCD Pro IS with the SKF Microlog Inspector / SKF
MARLIN handheld device, important machinery and process information may be stored for trending review. Data can also be transferred with the SKF system from the MCD Pro IS to @ptitude Inspector software for further detailed analysis.
ATEX and North America hazardous conditions
approvals – the SKF Machine Condition Detector
Pro IS provides for velocity, enveloped
acceleration and temperature monitoring with
general alarm capabilities.
Vibration monitoring
When performing measurements, the MCD Pro IS’s sensor input signal is processed to produce two vibration measurements for each
measurement POINT. Velocity vibration identifies phenomena that
are observable in the low to mid frequency range and indicates such
structural problems as misalignment, unbalance, mechanical looseness and more.
Events that occur in the higher frequency ranges, such as bearing
and gear problems, can also be detected by the MCD Pro IS with its
“acceleration enveloping” capability, a signal processing technique
that focuses on enhancing the repetitious vibration signals that characterize such problems.
Temperature
Temperature measurements enhance the “early warning” benefit of
the instrument by offering a useful indication of mechanical condition or the load applied to a specific component, since as a bearing or
its lubrication fails, friction causes its temperature to rise.
25
SKF Machine Condition Detector Pro IS CMVL 3600-IS
General alarm capabilities
When used as a stand-alone tool, the MCD Pro IS may be easily programmed for six alarm settings, which include the “alert” and “danger” levels for each of the three measurements.
When measurements are taken, current measured values are
automatically compared to six user-defined settings, and the MCD
Pro IS’s alarm indicator and LEDs react appropriately. An “alert” condition provides the user with an early warning of impending problems for which immediate in-depth analysis should be performed. A
“danger” alarm indicates that a problem has escalated to a point
where actions must be made quickly to avoid a serious failure.
When used with the SKF Microlog Inspector / SKF MARLIN, data is
logged for trending and percent change from last measurement and
baseline data.
SKF MARLIN QuickConnect
studs for quality, repeatable
data collection
Specially designed mechanical and computerized studs enable users to collect consistent, accurate and repeatable data from each measurement point. Engineered to work exclusively with the MCD Pro IS, the MQC mechanical and computerized
studs provide for a fast, quarter-turn connection that temporarily
fastens the probe to a measurement point. This reduces the possibility of errors and inconsistencies often resulting from data collected
by using varying methodologies.

Need to boost your plant’s
availability and reliability?
Start with operator driven reliability from SKF
For today’s power plants, optimizing output in the face of rising operating costs, reduced manpower and stringent regulations is a constant challenge. By enabling operators to take the lead in monitoring
and maintaining equipment, the proven operator driven reliability
(ODR) program from SKF is helping plants meet this challenge.
Why operator driven reliability?
Because of their proximity to equipment, operators are usually the
first to detect even the smallest changes in process conditions and
machinery health, including leaks, abnormal readings, excessive
heat, vibration or pressure.
In a successful ODR program, operators perform process parameter inspections, record and communicate observations on machine
performance, and make minor adjustments. Using technology to
automate these tasks facilitates consistency, accuracy and plantwide information sharing, all of which can enhance your production
and maintenance strategies.
With ODR, operators become an integral part of an overall reliability-based asset management strategy that can result in increased
productivity and reduced unplanned downtime.

SKF’s CMSS 93X-XX cables are premium sensor cables providing
superior performance in demanding environments.
CMSS 932 is a single or double shield, twisted pair cable with the
conductors individually insulated with a fluorine based polymer, a
braided shield with drain wire and an outer insulated jacket also
made of a fluorine based polymer. Two insulated conductors are
cabled together with one uninsulated drain wire and two glass cord
fillers. The double shielded option adds an inner shield of aluminum
polyester foil with drain wire.
The CMSS 933 has the same characteristics as the CMSS 932
cable, except the CMSS 933 is a three wire version for use with dual
temperature and vibration sensors. This cable does not have a double shielded option.
There are two wire colors (jackets) available:
• Yellow: For high visibility in the often dusty and debris laden industrial environment
• Blue: For use in intrinsically safe circuits in the Oil/Gas and Hydrocarbon processing industries
Recommended uses
The single shield cable is recommended for use with sensors in normal industrial applications where these cable types have been previously used and installed.
The double shield cable is highly recommended for use with sensors in industrial installations where there is a high noise field, such
as machine tools and power generating facilities. Double shielded
versions include:
• Inner shield = Isolated
• Outer shield = Non-isolated

Industrial cable connector assemblies for
vibration sensors
CMSS 932-68
The CMSS 932-68 are rugged cable connector assemblies designed
for use with piezoelectric vibration sensors, which require high specification shielded cable to maximize the quality of the signal transmitted to the monitoring system. The assemblies are ingress protection
rated (IP 68): allow no ingress of dust and are suitable for continuous
immersion in water. The CMSS 932-68 are two-wire assemblies
using a single or double shield, twisted pair cable with the conductors
individually insulated with a fluorine based polymer, a braided shield
with drain wire and an outer insulated jacket also made of a fluorine
based polymer.
The double shielded option adds an inner shield of aluminum
polyester foil with drain wire. There are two wire colors (jackets)

Industrialized cable connector assemblies for vibration sensors CMSS 932-68
Connectors
Ordering example
MIL-style stainless steel connectors are designed for use with SKF
sensors. There are two different styles of IP 68 connectors:
CMSS 932-68TLI-SY-10M
• Two-wire, IP 68 connector, twist lock, isolated, single shield,
yellow, 10 m (32.8 ft.) length
CMSS 932-68LCN-SY-20M
• Two-wire, IP 68 connector, locking collar, non-isolated, single
shield, yellow, 20 m (65.6 ft.) length
CMSS 932-68TLX-SY-XXM: IP 68 sensor/connector/cable
assembly with twist lock.
The fluoroelastomer boot and a quarter twist locks the assembly into
a tight fit.
Note: Isolated connectors cannot be selected with double shielded
cables (e.g., part number CMSS 932-68LCI-DY-XXM is not valid). As
such, if a double shielded cable is required (shield = D), select a nonisolated connector (non-isolated = N); for example:
• CMSS 932-68LCN-DY-5M
If an isolated connector is required (isolated = I), select a single
shielded cable (shield = S); for example:
• CMSS 932-68LCI-SY-5M
CMSS 932-68LCX-XX-XXX: IP 68 sensor/connector/cable
assembly with locking collar.
The locking collar is a threaded connector that threads onto an
accompanying sensor adapter. It is recommended to secure the sensor adapter to the accelerometer connector using thread lock (Loctite). The locking collar features an O-ring and metal locking ring and
is therefore more suitable for applications under water.
Double shielded cable should be grounded on both sides: the instrument side and the sensor side (through the machine). If an isolated
connector is selected with a double shielded cable, the sensor side
will be cut off and never connected to the sensor ground.

SKF – the knowledge engineering
company
From the company that invented the selfaligning ball bearing more than 100 years
ago, SKF has evolved into a knowledge
engineering company that is able to draw on
five technology platforms to create unique
solutions for its customers. These platforms
include bearings, bearing units and seals, of
course, but extend to other areas including:
lubricants and lubrication systems, critical
for long bearing life in many applications;
mechatronics that combine mechanical and
electronics knowledge into systems for more
effective linear motion and sensorized solutions; and a full range of services, from design and logistics support to condition monitoring and reliability systems.
Though the scope has broadened, SKF
continues to maintain the world’s leadership
in the design, manufacture and marketing of
rolling bearings, as well as complementary
products such as radial seals. SKF also holds
an increasingly important position in the
market for linear motion products, highprecision aerospace bearings, machine tool
spindles and plant maintenance services.
The SKF Group is globally certified to ISO
14001, the international standard for environmental management, as well as OHSAS
18001, the health and safety management
standard. Individual divisions have been
approved for quality certification in accordance with ISO 9001 and other customer
specific requirements.
With over 120 manufacturing sites worldwide and sales companies in 70 countries,
SKF is a truly international corporation. In
addition, our distributors and dealers in
some 15 000 locations around the world,
an e-business marketplace and a global
distribution system put SKF close to customers for the supply of both products and
services. In essence, SKF solutions are available wherever and whenever customers
need them. Overall, the SKF brand and the
corporation are stronger than ever. As the
knowledge engineering company, we stand
ready to serve you with world-class product
competencies, intellectual resources, and
the vision to help you succeed.

Evolving by-wire technology
SKF has a unique expertise in the fast-growing bywire technology, from fly-by-wire, to drive-bywire, to work-by-wire. SKF pioneered practical flyby-wire technology and is a close working partner
with all aerospace industry leaders. As an example,
virtually all aircraft of the Airbus design use SKF
by-wire systems for cockpit flight control.
SKF is also a leader in automotive by-wire technology, and has partnered with automotive engineers to develop two concept cars, which employ
SKF mechatronics for steering and braking. Further by-wire development has led SKF to produce
an all-electric forklift truck, which uses mechatronics rather than hydraulics for all controls.

Harnessing wind power
The growing industry of wind-generated electric power provides a source of
clean, green electricity. SKF is working closely with global industry leaders to
develop efficient and trouble-free turbines, providing a wide range of large,
highly specialized bearings and condition monitoring systems to extend equipment life of wind farms located in even the most remote and inhospitable
environments.
Working in extreme environments
In frigid winters, especially in northern countries, extreme sub-zero temperatures can cause bearings in railway axleboxes to seize due to lubrication starvation. SKF created a new family of synthetic lubricants formulated to retain
their lubrication viscosity even at these extreme temperatures. SKF knowledge
enables manufacturers and end user customers to overcome the performance
issues resulting from extreme temperatures, whether hot or cold. For example,
SKF products are at work in diverse environments such as baking ovens and
instant freezing in food processing plants.
Developing a cleaner cleaner
The electric motor and its bearings are the heart of many household appliances. SKF works closely with appliance manufacturers to improve their products’ performance, cut costs, reduce weight, and reduce energy consumption.
A recent example of this cooperation is a new generation of vacuum cleaners
with substantially more suction. SKF knowledge in the area of small bearing
technology is also applied to manufacturers of power tools and office
equipment.
Maintaining a 350 km/h R&D lab
In addition to SKF’s renowned research and development facilities in Europe
and the United States, Formula One car racing provides a unique environment
for SKF to push the limits of bearing technology. For over 60 years, SKF products, engineering and knowledge have helped make Scuderia Ferrari a formidable force in F1 racing. (The average racing Ferrari utilizes around 150 SKF
components.) Lessons learned here are applied to the products we provide to
automakers and the aftermarket worldwide.
Delivering Asset Efficiency Optimization
Through SKF Reliability Systems, SKF provides a comprehensive range of
asset efficiency products and services, from condition monitoring hardware
and software to maintenance strategies, engineering assistance and machine
reliability programmes. To optimize efficiency and boost productivity, some
industrial facilities opt for an Integrated Maintenance Solution, in which SKF
delivers all services under one fixed-fee, performance-based contract.
Planning for sustainable growth
By their very nature, bearings make a positive contribution to the natural
environment, enabling machinery to operate more efficiently, consume less
power, and require less lubrication. By raising the performance bar for our
own products, SKF is enabling a new generation of high-efficiency products
and equipment. With an eye to the future and the world we will leave to our
children, the SKF Group policy on environment, health and safety, as well as
the manufacturing techniques, are planned and implemented to help protect
and preserve the earth’s limited natural resources. We remain committed to
sustainable, environmentally responsible growth.
