Material: Stainless steel 1.405 (AISI 431).
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, 32, 38 and 48 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.
Temperature range: -30° to +85°C. * with coated surface
