Clamping Elements RCK 10-120 pages

Clamping Elements Type RCK 10 to 12
These shaft clamping elements provide maximum torque transmission from a single
unit, but, due to their large clamping surfaces clamping pressures are kept to
reasonable levels. The design enables automatic centring between shaft and hub,
and axial positioning of the hub does not change during clamping. Suitable for
applications with high bending loads.

For thin walled hubs, such as Conveyor Drums, the surface pressure on the hub can
be reduced by reduction of the clamping torque applied to the Clamping Screws
down to a minimum of 50%; the pressure on the outer hub and torque transmitted
being reduced proportionaly, so that wall thickness of 12% of the internal diameter
can be used.
Recommended tolerances for full
torque transmission both shaft and
hub should be within the following
tolerances:
Shaft
Hub

Clamping surfaces to be finished to
Rz ≤ 15 µm.
These units ideal for mounting of
wheels and belt conveyor pulleys.
X = Distance required to remove
screws, additional clearance for alan
key may be required.
