SUPER-THIN-WALLED ROLLING BEARING AND ITS RETAINER

摘要

PROBLEM TO BE SOLVED: To surely control a gap in a radial direction of a segment forming a retainer of a super thin-walled bearing and to improve work efficiency for combining respective segments. SOLUTION: A cylinder-shaped connecting surface 45A and spherical connecting surface 46A are formed at one of a connecting portion A of the segment 40. These connecting surfaces 45A and 46A are respectively connected with a cylinder-shaped connecting surface 45B and spherical connecting surface 46B formed in a connecting portion B of a counter-segment 40 in a radial direction at a concavo-convex connecting state, and pulling-out of respective segments 40 can be prevented in a radial direction accordingly.
