Abstract

A bearing cage assembly comprises multi-group rollers (2), each group has multiple rollers, and each roller is a barrel roller, multiple rollers are stacked together to form a group of rollers, and the end surfaces of each two adjacent rollers contact with each other. Multiple groups of pockets (11) are formed in the cage, and each group of pockets has multiple pockets. The pockets in any group are distributed along the circumference direction of the said cage, and a group of rollers is disposed in each pocket. Multi-group rollers can roll in circumferential direction of the cage. During the rolling process, a great number of contact points are distributed on the raceways, thus the load capacity of the bearing is improved, the friction resistance is low, suitable for the fields where high speed operation is necessary. A planar thrust bearing, a radial bearing and a conical radial-thrust bearing are provided.
