Roller bearing, particularly single row ball bearing, has two bearing rings, roller body and cage which leads roller body, where surface of roller body forms rolling contact with track of two bearing rings

摘要

The roller bearing (1) has two bearing rings (2,3), a roller body (4) and a cage (5) which leads the roller body. The surface of the roller body forms a rolling contact with a track of the two bearing rings. The cage is formed of a temperature-resistant plastic. A solid lubricant is embedded in the plastic of the cage. The solid lubricant is graphite, particularly, lamellar graphite. The solid lubricant is present as particles (6) with a diameter of certain micrometer. The reinforcing fibers (7) of carbon are arranged in the plastic.
