Integral type thrust bearing has flanges, provided on inner-diameter side of inner ring and outer-diameter side of outer ring, which restrict radial gap in bearing to prevent bearing rings and retainer separating from each other

摘要

The bearing includes a retainer (2) formed with pockets for radially housing multiple rollers, and inner and outer rings (3,4) having flanges (4a) on their inner-diameter side and outer-diameter side, respectively. The flanges restrict a radial gap in the bearing, so that both bearing rings and retainer are inseparable from each other. The bearing rings and retainer are assembled together with rollers into a bearing body with the bearing rings and retainer not hardened, thus the bearing body is subjected to carburizing, hardening and tempering.
