Document Type and Number:
WIPO Patent Application WO/2024/053142
Kind Code:
A1
Abstract:
This roller bearing comprises: an inner race and an outer race; a plurality of rollers; and a holder on which a plurality of columnar parts extending in the axial direction of the central axis are provided along the circumferential direction, and a roller is held between two columnar parts adjacent in the circumferential direction among the plurality of columnar parts. As viewed in the axial direction of the central axis, when a pocket gap is defined as the distance obtained by subtracting the maximum diameter of the rollers from the distance along the pitch circle between a first columnar part and a second columnar part adjacent in the circumferential direction, a pocket gap ratio obtained by dividing the pocket gap by the maximum diameter of the rollers is greater than or equal to 0.005 and less than 0.01.
