Title:
BEARING WITH SEAL
Document Type and Number:
WIPO Patent Application WO/2022/202545
Kind Code:
A1
Abstract:
This bearing with a seal makes it possible to achieve a hydrodynamic lubrication state between a seal sliding surface and a seal lip of a sealing member through use of a plurality of protrusions of the seal lip. Even when oil is not supplied from the outside, the bearing with a seal is prevented from running short of oil between the protrusions and the seal sliding surface. A seal lip (10) comprises a grease storage (15) formed in a recessed shape so as to retain grease (G). The grease storage (15) is formed in a connection portion (14) being a portion between the protrusions (12) adjacent to each other in the circumferential direction.
