Document Type and Number:
WIPO Patent Application WO/2022/071172
Kind Code:
A1
Abstract:
[Problem] To provide a rolling bearing which uses a highly reliable retainer, wherein: the dimensional stability required for a retainer, especially for an outer ring guided retainer, the ductility required for a crown retainer, and the adhesive power of a grease that uses a poly(α-olefin) oil or the like as a base oil are improved; and deformation at a high speed is able to be prevented. [Solution] With respect to a rolling bearing according to the present invention, said rolling bearing being composed of at least an inner ring 1, an outer ring 3, a synthetic resin retainer 9 and a rolling body 7, the synthetic resin retainer 9 is formed of a polyamide resin composition that is composed of a polyamide 410 and a reinforcing fiber material, the content of which is set within the range of from 0% by weight to 40% by weight.
