Tested Tough
Engineers from Baldor’s Advanced Development Laboratory designed and tested the Raptor to perform under the most
extreme conditions. This includes successfully passing the rigorous DIN 740 (reverse cyclic loading) coupling test
standard – not once, not twice, but ten times for a single coupling.
Immediately Increase Life in Existing Applications
Designed to be a drop-in interchange, the Raptor meets or exceeds torque, bore, and speed ratings for these styles of
commonly used couplings. All Raptor components can be used in existing applications without any modifications. This
allows current users of these styles to immediately realize the benefit of longer driven equipment life and improved
reliability by switching to the Raptor.

Baldor•Dodge Raptor Coupling
Longer Driven Equipment Life and
Improved Reliability
Superior Natural Rubber
Element
Leveraging over 50 years of Dodge’s natural rubber
expertise, the Raptor features a natural rubber
flexible element that offers a number of performance
benefits when compared to competitive urethane
designs.
• Static conductive for grounding redundancy,
allowing current to safely pass through the
natural rubber element, preventing the possibility
of arcing during operation
• Exceptional resistance to hydrolysis, for improved
performance in humid environments
• Superior thermal conductivity and ability to
dissipate heat and hysteresis build up
Lower Stiffness, Longer Driven Equipment Life
Because the Raptor element uses a natural rubber compound, it is significantly more flexible than urethane designs.
Natural rubber yields an element with approximately 50% lower torsional and bending stiffness, resulting in longer
life for all types of connected driven equipment – including motors, pumps, compressors and gearboxes.
•Reduced bearing loads yield up to a 16.7 times increase in L10 bearing life in connected equipment
•Less vibration transmission to connected equipment
•Better shock damping capabilities
Results based on tested bending stiffness
values applied to a motor and centrifugal pump
arrangement with 4° angular misalignment.

Industry Leading Misalignment Capabilities
Over time foundations settle, vibration occurs, and some level of misalignment may occur. While competitive urethane
couplings can handle pure angular or parallel misalignment, their capabilities are greatly diminished in applications
with combined angular and parallel misalignment. Unfortunately for the competition, combined misalignment is reality.
When an elastomeric coupling is misaligned during operation, cyclic stresses are created, generating heat in a
phenomenon known as hysteresis. The Raptor’s natural rubber element has superior heat dissipating capabilities
versus competitive urethane elements. Additionally, the Raptor has a lower angular stiffness, allowing it to be
more forgiving in misaligned conditions.
These two features combined allow the
Baldor•Dodge Raptor to offer industry
leading misalignment capabilities.
The Raptor provides accommodation of
shaft misalignment during installation,
operation, and replacement better than
competitive urethane elements.
Attention to Every Detail
Baldor highly engineered every aspect of the Raptor for
performance, including specification of high-strength
Grade 8 flanged head cap screws. This robust hardware
gives a 40% increase in proof strength versus competitor’s
standard head Grade 5 fasteners. Serrations under the
flanged head help to resist loosening and minimize the
potential for stripping. This attention to detail provides a
more reliable connection between elastomeric element and
shaft hubs.

Baldor•Dodge Raptor Coupling
Easier Installation and Reduced
Maintenance
Improved Features, Easier
Installation
Raptor’s slotted clamp rings offer more clearance
at the bolt holes, for an easier installation than
competitive designs.
The Dodge Raptor has everything needed for easier
installations and reduced maintenance costs.
• Split element for easy replacement without moving and
re-aligning connected equipment
• Slotted clamp ring holes offer 187% extra mounting
hardware clearance versus competitor’s circular through holes.
• Approximately 50% lower torsional stiffness makes the
element significantly easier to manipulate by hand during
installation
• Maintenance free non-lubricated natural rubber element
for trouble-free operation
Easy as 1-2-3
Installation for Dodge Raptor couplings are quick and easy. The Raptor’s horizontally split element doesn’t require
locking shafts during installation, meaning a faster installation, requiring fewer tools and eliminating shaft damage.
Simply fasten the shaft hubs, install the element, and tighten the hardware.

Suited For Any Application
A Practical Solution to
Spacer Couplings
The innovation behind the Raptor coupling also extends to
applications requiring additional space between shaft ends.
• One spacer element fits all standard ANSI and ISO
spacer lengths
• Spacer elements can be replaced with standard closecoupled elements, resulting in lower replacement costs
and reduced inventory
• Eliminates the need for high-speed rings, resulting in
easier installation, while also reducing purchase costs
and inventory requirements
Armored Elements for Extra Protection from Harsh Environments
Raptor elements are available with an optional Armored
Element. This allows users to benefit from the increased
performance and longer driven equipment life of standard
Raptor elements, while providing an added layer of protection
from ozone, petroleum oils, and some chemical environments.
Raptor Armored Elements exceed ASTM 1149-07 rubber
deterioration standards, as determined through third-party
testing.
Third-Party ATEX Certified
When it comes to applications in hazardous environments,
there’s no reason for customers to assume any risk by using
a product which is self-certified. That’s why all Raptor
couplings are third-party ATEX certified for worry-free use
in hazardous environments. All required product markings
and documentation are included with each coupling
at no additional charge. When it comes to hazardous
environments, you can trust Baldor•Dodge.

Selection Methods:
TORQUE METHOD:
Step 1: Obtain required service factor from Service
Factor Tables on pages 14 and 15
Step 2: Determine torque required for application.
Torque (In - lbs) = 63025 x HP x SF
Coupling RPM
Step 3: From Rating Tables, find a rating equal to or greater than the torque. Note coupling size from left hand column.
Step 4: Check maximum RPM capability
Step 5: Check maximum bore capacity. If maximum bore is exceeded, move to larger size with adequate bore. Be
sure maximum RPM of coupling is not exceeded
Notes: 1. If system peak torque is known and is non-reversing, start at Step 3. If system peak torque is known and reversing,
multiply by 2.0 and start at Step 3.
2. If ambient temperature of the application is above 180°, a high temperature adjustment must be made
to the system service factor. See page 29 (or 28, if the current page 28 is removed) for high temperature
adjustment factors.
3. If spring set motor brake is used, and brake HP is greater than prime mover, use brake HP in place of motor HP.
HP/100 METHOD:
Step 1: Obtain required service factor from Service Factor Tables on pages 14 and 15
Step 2: Determine the application HP per 100 RPM:
HP / 100 RPM = Motor HP x 100 x Service Factor
Coupling RPM
Step 3: From Rating Tables, find a rating equal to or greater than HP design. Note to or greater than the HP/100 RPM.
Note coupling size from left hand column.
Step 4: Check maximum RPM capability.
Step 5: Check maximum bore capacity. If maximum bore is exceeded, move to larger size with adequate bore. Be sure
maximum RPM of coupling is not exceeded.
