ABSTRACT:
The invention contemplates a removable-seal configuration for an axial end of an antifriction bearing wherein seal components are fixedly held by the outer bearing ring and position a seal ring in yieldable circumferentially continuous wiping contact with a seal surface on the inner bearing ring. The component seal parts comprise a stiff annular backing ring, and a stiff removable split ring, with a yieldable annular seal ring compressed between the stiff rings and having the wiping contact with the inner ring. The outer ring has a shouldered groove to retain the component seal parts, the groove having a section of continuously curving contour and being characterized by a convergent ramp with which a similarly sloped bevel of the split ring has wedging contact to derive the indicated compression of the yieldable seal ring.
