ABSTRACT:
To provide a ball bearing that insures reasonable endurance and which reduces the necessary torque for rotation while causing less fluctuations in torque, a synthetic resin cage of the ball bearing for retaining a plurality of balls so as to roll freely is impregnated with a lubricating oil having a viscosity of 10 to 150 mm.sup.2 /s at 40.degree. C. in an amount of 0.1 to 1.0% by weight of the cage, a film of the lubricating oil is formed in a thickness of 0.03 to 20 .mu.m on the surfaces of an inner race, an outer race, balls and the cage, and the amounts of the oiliness agent and the rust inhibitor that are to be contained in the lubricating oils are limited to the specified ranges.
