Description
Material
Stainless steel 1.4057.
Version
Bright.
Note
Shrink disc to connect a hollow hub to a shaft. They are mounted on the OD of the hub and generate pressure on the hub wall by reducing the ID with wedge-formed rings, creating a press fit between the hub and shaft. They are suitable for static, dynamic and shock loads.
- for extremely high torques
- no axial shaft/hub offset when assembling
- self-centering
The version 23380-01-4072 has high tensile ISO 4762 screws.

Assembly
Remove existing transportation locks. Clean and lightly oil shaft, internal and external hub diameters. Do not use MoS2 or grease. Slide shrink disc onto hub. Then slide unit (shrink disc/hub) onto shaft and position correctly. Gently tighten clamping screws one after the other by hand. Then use a torque wrench to tighten the clamping screws crosswise in several increments to the defined tightening torque MS.
1st increment approx. 33% MS
2nd increment approx. 66% MS
3rd increment 100% MS
Dismantling: Gradually loosen all screws one after the other but do not fully remove from the thread. The shrinking disc usually loosens itself.
