Shrink disc 23380

Shrink discs Form A Material: Steel. Version: Bright. Note: Shrink disc to connect a hollow hub to a shaft. They are attached to the outside of the hub and generate pressure on the hub by reducing its internal diameter over tapered surfaces. This creates 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-centring 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 one after the other 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.
