Abstract

PURPOSE: To prevent the penetration of water or alien substances by fitting the elastic seal bodies on the inner surfaces of the inner rings which are adjoined to each other.
CONSTITUTION: The single row outer ring 3 has the end surface sealing mechanism which is constituted of the holding ring 5 fitted on the end surface on the small diameter side and the oil seal 51. On one end of the inner peripheral surface of the small flange on the end surfaces side, which are opposit to each other, of the inner ring 1, the expanded part 61 for fixing is fixed in the groove 142, and on the other end side, the elastic seal body 6 with the sliding seal lip 62 which contacts the other groove is provided to seal between the opposing surfaces.
