Since the moveable parts of universal joints with friction bearings DIN 808 are not surface treated, i.e. not case-hardened, the possible applications are much more limited compared to the ones made of steel. Therefore, the guidelines for the selection of universal joints with friction bearing may be applied at a limited extent only. RPM over 200 may become critical.
For stainless steel universal joints, ample lubrication is especially important. This can be achieved by fitting the joint with a grease filled GN 808.1 cover boot.
The “How to order” example refers to universal joints with equal bores d2 or s at both ends.

Cross holes in universal joint shafts and in universal shafts are suitable for making shaft-hub connections using a pin or a grub screw. For bores with keyway or square, they serve to secure the axial position of the universal joint and shaft. The d2 pin hole with H11 tolerance is intended for use with spiral spring pins.
