Product DescriptionRCK71-25x50 Shaft Clamping Element
The RCK 71 is a type RCK 70 with addition of a distance ring to prevent axial movement of the hub during clamping. Due to the additional friction between the element and hub during clamping maximum torques are reduced, but with reduction in surface pressures also. This design can be mounted within the confines of a hub providing a stepped bore is provided to accommodate the flange.
Recommended tolerances for full torque transmission are:-
X = Distance required to remove screws, additional clearance for allen key may be required.
