Notes

The service-proven non-contacting bushing seal with low gas consumption. Non contact type carbon rings are segmented rings held together by a garter spring at the outer diameter. A defined minimum radial gap provides a contact- free operation. Robust design and reliable operation provide secure oil sealing even at extreme conditions.

Dimensions on request.
