Abstract

PURPOSE: To make the mounting and removing of the bearing to the device easy and to improve the sealing capacity by providing the seal holding ring on the end surface side on the small diameter side of each other ring.
CONSTITUTION: The outer ring 2W5 are constituted by the outer race 12 and the tapered single row inner race which oppose the outer rance 12. On the small diameter end surface side of the outer rings 2W5, the seal holding rings 71W74 to hold the sealing bodies 81W85 are clamped on the step parts of the outer races 2W5. The sealing bodies 81W84 mainly composed of rubber or synthetic resin are held on the inner peripheral side of the seal holding rings 71W74, and the seal lips of the sealing bodies 81W84 are fitted slidable with the outer peripheral surface of the extended cylindrical part 14 of the inner ring.
