Abstract

PURPOSE: To put reliable and durable sealing in simple structure where a seal is put in a ring groove between the outer ring and the seal reain ring to seal the space between the inner race and the outer race.
CONSTITUTION: An external ring 3 is shaped by projecting a small jaw side end of a bearing inner race 2a axially from the edge 2h of the trace face 2g of a bearing outer race 2b, A ring groove 5 is made between the external ring 3 and a seal retain ring 4 which is fit closely on the side end of the bearing outer race 2b and is fixed in a housing 1. For filling the ring groove 5, the seal 6 is retained in the seal retain ring 4 to seal the clearance between the outer race and the inner race of the bearing. The seal is made up easily, has high reliability and durability, and is easily assembled or disassembled.
