摘要

The hub seal system for hubs fitted with ball bearings comprises a locking ring (16) and a sealing ring (19) mounted on its inner side. A second ring (10) is mounted on the inside of this and is supported axially by the ball bearing. The sealing ring is supported by the outer surface (44) of the second ring and has an outer diameter which is greater than the inner diameter of the locking ring.
