Title:
SEAL-ATTACHED BEARING
Document Type and Number:
WIPO Patent Application WO/2022/181437
Kind Code:
A1
Abstract:
In a seal-attached bearing which can cause a gap between a seal lip and a seal sliding surface to be in a fluid lubrication state by means of a plurality of protrusions of the seal lip, the stick-slip phenomenon of the protrusions is suppressed. The protrusions (12) have corner sections (12a, 12b) that are bent from middle portions in the height direction of the protrusions (12) to a base side so that the circumferential widths W of the protrusions (12) gradually widen toward the base side. Accordingly, the stick-slip phenomenon is suppressed by improving the strength near the bases of the protrusions (12).
