Pivoting roller bearing with seals

摘要

The bearing has inner (1) and outer (2) rings. The outer ring has a spherical running groove (2a), whose centre of curvature is located in the centre (0) of the bearing. A sealing element (7) is fixed onto one bearing ring. Its lip (9) is in contact with a sealing surface (10) which is integrated with the end of the other bearing ring. The sealing surface is spherical, and its centre of curvature is located in the centre of the bearing. It may also be a conical surface, which is similar to a spherical surface whose centre of curvature is located in the centre of the bearing.
