Abstract
A rolling bearing according to the present invention comprises an inner race 29, an outer race 31 and a plurality of balls 37 disposed therebetween. The inner race 29 has a raceway surface on its outer peripheral surface. The outer race 31 includes a raceway surface on its inner peripheral surface. The balls 37 are rotatably interposed between the raceway surfaces of the inner and outer races. A lubricant is enclosed in a space 41 formed between the raceways of the outer and inner races by an amount of 0.3% to 3% of the capacity of the space.
