Materials

Rings:
Basically RHD rings are made from vacuum degassed chrome steel 100Cr6, which is heat stabilized for temperatures up to 150° C (302° F). On request, an additional heat stabilization can be carried out for working temperatures between 150° C and 300° C (572° F). Bearings for working temperatures up to 500° C (932° F) are made of high temperature tool steel.

Balls:
Standard material for balls is vacuum degassed chrome steel 100Cr6. For the increase of speed value and lifetime, all bearings can be delivered with ceramic balls.

Further special materials are available on request.
