ABSTRACT:
A crown-shaped cage for a radial bearing has a plurality of pockets for receiving balls. The pockets, which have their respective entrances axially on one side of the cage, are spaced from each other at regular intervals in a circumferential direction by partition walls. Each of the partition walls has engagement portions in an inside part thereof at positions opposite the pockets on both sides thereof, the engagement portions on both sides of each of the pockets being to be engaged with each ball so as to stop the ball in radial and axial directions. In each of the partition walls is provided a relief space for allowing deflection caused in the partition walls when the ball is inserted in the pocket. The crown-shaped cage can be made of even a plastic material such as PPS, PEEK or the like which offers excellent heat resistant but low flexibility, due to the presence of the relief space and the engagement portions provided in the inside part of the partition walls.
