摘要

PROBLEM TO BE SOLVED: To reduce noise and a carrier air amount, and to prevent variation in bearing temperature due to oil retention with less amount of air. SOLUTION: A slant part 2b connected to rolling surface 2a of an inner ring 2 rolls is provided to an outer diameter surface of the inner ring 2 of the rolling bearing 1, and a nozzle member 6 along the slant part 2b with a gapδis provided. The slant part 2b of the inner ring 2 is provided with a circumference groove 7. A discharge hole 8 for an air oil opening opposite to the circumference groove 7 is provided.
