Anti-friction bearing for motor vehicle, has fixed channel with downstream end emerging in lateral space, and rotating channel with upstream end emerging in space for realizing air passage between air passage module and rotating unit

摘要

The bearing has a lateral space (28) sealed by a front sealing device (35), and a sealing device (36) between an air passage module (22) and a rotating unit (1), where the spacing is formed in a lateral housing . A fixed channel (26) has a downstream end emerging in the space, and a rotating channel (27) has an upstream end emerging in the space so as to realize an air passage between the module and the unit across the space.
