Abstract
A rolling bearing as a ball bearing comprising an inner ring; an outer ring having the same axial width as said inner ring; balls arranged between said inner ring and said outer ring; and a sealing member having a roughly channel-shaped configuration in cross section projecting from both end faces of said inner ring and said outer ring. A relation between a diameter A of said ball and an axial width W of said inner ring and said outer ring satisfies A/W≧0.4, and a relation between a bearing volume V of said ball bearing and an internal space capacity C of said ball bearing satisfies 0.35≦C/V≦0.55.
