Material: high-quality steel

The clamping bush consists of a double-walled steel sleeve filled with a pressure medium, and a flange part. Inside the flange there is a screw and a piston with seal to build up compression.

Function: When the thrust screw is tightened, the sleeve expands uniformly against shaft and hub, creating a rigid connection through frictional force. When the thrust screw is loosened, the bush returns to its initial position and can be easily disassembled.

Concentricity: 0,02 mm.
Tolerances:
Shaft h7 for d = 15 mm.
Shaft k6-h7 for d = 19, 22, 24, 28 and 38 mm.
Shaft h8 for the other diametres d.
Hub H7.

MN = transmittable torque at load of 0. If the screws are fastened with Manz.
Fa = transmittable axial force at torque of 0. If the screws are fastened with Manz.
Fr = Maximum transmittable radial force.
Manz = required fastening torque for the screws.
