Proportionally effects size of the clamping force and the clamping torque and it is a constant for each specific pressure connection. It depends on the sliding friction factor, such as, shape deviation, material heterogeneity, method of creating the pressure connection, and others.
The clamping factor is affected when it is greater:
- At nonlubricated pressure connections.
- In the longitudinal direction than in the circumferential.
- For loosening than for sliding.
- For a pressure connection made by shrinkage than for pressure connection made by expansion and pressing.
