RADIAL ROLLER BEARING, IN PARTICULAR FOR THE ROLLER BEARING MOUNTING OF SHAFTS IN INTERNAL COMBUSTION ENGINES

摘要

A radial roller bearing, which has an outer bearing ring and a multiplicity of cylindrical roller bodies which roll on the inner lateral surface of the outer bearing ring and the outer lateral surface of an inner bearing ring or a shaft. The roller bodies are held at uniform intervals by a bearing cage with inwardly directed radial rims for axial guidance. Lubricating openings, which lead from the outside into the bearing interior, supply lubricant, and are arranged on the outer or inner bearing ring axially at both sides. The lubricating openings are cutouts which are formed into one or both axial sides of the bearing rings, outside a load zone of the bearing rings, which extend into the outer or inner raceway of the roller bodies and in which the roller bodies are arranged so as to be partially freely accessible for receiving oil form the bearing surroundings.
