Abstract

A bearing for oscillating angular movement including inner and outer bearing parts with rollers therebetween, and with one or more swivel members between at least some of the adjacent rollers. Each swivel member comprises a central part of smaller diameter than a roller, and inwardly and outwardly extending portions having supporting faces which engage the inner and outer bearing parts. Because each swivel member occupies a smaller space circumferentially of the bearing than does an individual roller, the total number of members available to transmit loads between the inner and outer bearing parts is increased, thereby improving the capacity of the bearing. The bearings are particularly useful for Hookes universal joints.
