<p><P>PROBLEM TO BE SOLVED: To provide an angular bearing capable of improving a filling rate without remarkably increasing a width dimension of the bearing, and improving the load capacity. <P>SOLUTION: This angular bearing 1 comprises balls 10, a ball-cage 12 holding the balls, and inner and outer rings 14, 16. The inner and outer rings respectively have inner and outer raceway faces 14a, 14b kept into contact with the balls at specific contact anglesθ<SB>1</SB>,θ<SB>2</SB>to the radial direction. A zigzag recessed part receiving the balls of a plurality of rows 18a, 18b is formed on a peripheral face of one ball-cage 12, and the balls of the plurality of rows 18a, 18b different from each other in pitch circle diameters d<SB>1</SB>, d<SB>2</SB>are arranged in the axial direction of the angular bearing at intervals (a) less than ball diameters D<SB>1</SB>, D<SB>2</SB>. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
