Abstract

PURPOSE: To eliminate the sled of the retainer for a ball bearing due to the centrifugal force when the bearing rotates at high speed by increasing the weight of the annular portion of the retainer and decreasing the total weight of a post to thereby increase the ratio therebetween.
CONSTITUTION: A retainer 4 consists of posts 6 for partitioning a pocket for retaining and guiding balls 3, and an annular portion 7 for coupling the posts 6 with an escape 12 in the boundary between the side surface 10 of the annular portion 7 and the outer peripheral surface 11 of the inner guide surface. Thus, when the bearing is assembled with seal, it prevents the retainer 4 from interfering with the seal. The outer peripheral surface 13 of the post 6 facing with the side of an outer race 1 is formed in tapered state to reduce the thickness toward the end 15 from the root 14 of the post so as to thereby lighten the total weight of the posts. The axial width size l of the annular portion 7 is increased to thereby increase the weight of the annular portion 7. Accordingly, the ratio of the annular portion 7 in weight to the posts 6 in total weight becomes larger to thereby eliminate the sled of the retainer 4 due to the centrifugal force when the bearing rotates at high speed.
