Materials and finishes

Selection and application

Installed laterally relative to the shaft axis. For DIN 6799, the ring designation refers to the groove diameter; the compatible shaft diameter is a separate range. Check both before selecting a variant.

Other materials and finishes are available on request. Configuration and supply are confirmed against the specific enquiry.
