Rolling bearing e.g. clutch release bearing has rings and abutment element which are connected with contact portion, and coefficient of thermal expansion material having layers is different from ring fixed with sealing element

摘要

The bearing has rings (2,3) which are provided between rings shifting rolling element. The assembled position of the ring is rotated relative to the ring. A sealing element (5) is in contact sealing in the gap between the rings. The rings and an abutment element (7) are connected with an annular or sleeve-like peripheral contact portion (9). The coefficient of thermal expansion material having layers (10,11) is different from the ring fixed with sealing element. An independent claim is included for method for keeping moderate temperature of rolling bearing.
