Catalog excerpts

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.

A light duty series RCK 10, a normal duty series RCK 11, and a Heavy duty series RCK 12 for maximum torque applications. *Minimum outside diameter of hubs manufactured in medium carbon steels with yield strength ≥ 320 N/mm .
