Abstract
A lubrication film 5 is formed of a solid lubricant including PTFE (polytetrafluoroethylene) having a mean molecular weight of not more than 25,000 and a mean particle size of not less than 5 .mu.m and less than 10 .mu.m. The films 5 adhere to balls 3, raceway tracks 1a, 2a and a retainer 4 of a bearing assembly. The solid lubricant thus adhered to each portion has a property that PTFE particles are dispersed without a binder.
