ATTENTION! In the area of the position of the external clamping set the external surface of the hub (outside hollow shaft) can be greased. CAUTION! Before tightening the clamping screws install the shaft. • Slightly tighten the clamping screws manually. • Afterwards tighten the clamping screws evenly and successively in several revolutions (see picture 5) until the front, screw head-sided surfaces of the outer and the inner ring are flush. Thus the correct clamping of the outer and the inner ring can be visually checked (see picture 6). When tightening the clamping screws the max. screw tightening torque indicated (see table 1) must not be exceeded. ) ATTENTION! Subject to the QPQ coating the internal ring may protude by up to 0,5 mm. picture 3: push the clamping set onto the hollow shaft picture 4: push onto the shaft picture 5: tightening of the clamping screws picture 6: visual check Table 1: type of clamping set screw size M tightening torque TA [Nm] Schutzvermerk ISO 16016 beachten.

Loosened or falling drive parts can cause injuries to persons or damages to the machines. Safe the drive parts before the disassembly. • Detach all clamping screws evenly and successively in several revolutions.Do not unscrew the clamping screws completely from the thread. ! CAUTION! To reduce the tension forces the clamping screws must not be unscrewed completely. • Detach the outer taper ring by means of the pull-off threads and some clamping screws, quantity dependent on the pull-off threads in the inner ring. The outer taper ring must be pulled as long as this is completely detached. • Remove shaft from the hub/hollow shaft. • Draw the clamping set KTR 620 off the hub/hollow shaft. ! CAUTION! In case of non-observance of these hints or in case of non-considerance of the operating conditions regarding the selection of the clamping set, the function of the clamping set can be influenced. Disposal of waste: Defective clamping sets must be cleaned and scrapped. Remark for the use in explosive applications according to ATEX 95 For the use in explosive applications the type and size of clamping set (applying for category 3 only) has to be selected in a way that starting from the peak torque of the machine including all operating parameters to the rated torque of the clamping set there is a service factor of at least s = 2. CLAMPEX® clamping sets are not part of the standard 94/9/EG, since • this product is a torsionally rigid, backlash-free, frictionally engaged connection with one or more taper clamping ring(s) by means of several screws. (Clamping screws have to be secured, e. g. by means of a medium strength adhesive). • due to the design of clamping sets a fracture/failure does not have to be expected (frictional heat is only caused by improper assembly/tightening torques, i. e. not in case of proper use).

Frequently asked questions
The CLAMPEX 620 is designed for cylindrical shafts without feather keys.
Ensure the front, screw head-sided surfaces of the outer and inner ring are flush. This visually confirms the correct clamping.
The maximum tightening torque for the clamping screws varies depending on the screw size. Refer to Table 1 in the manual.
