|1. (WO2017150544) BEARING WITH SEAL|
|Title:||BEARING WITH SEAL|
A protrusion (152) is formed in a sealing lip (151). An oil passage (170) is formed between the sealing lip (151) and a seal sliding surface (112) that slides in a circumferential direction relative to the protrusion (152), the oil passage communicating across a bearing interior space (160) and the exterior and not allowing foreign substances of a predetermined particle size pass through. As the bearing rotates, lubricating oil in the oil passage (170) is drawn into between the sealing lip (151) and the seal sliding surface (112), and forming of an oil film is facilitated. To prevent burrs from being generated in a distal end (153) of the sealing lip (151), a flat surface (155) is placed between the protrusion (152) and the distal end (153) of the sealing lip (151).
