发明名称 RADIAL NEEDLE BEARING
摘要 PROBLEM TO BE SOLVED: To provide a radial needle bearing in which even in a case where the raceway surface of a support shaft is inclined, the raceway surface of the support shaft and a needle, which is at least in the negative area of a radial load, evenly contact with each other, and it is not necessary to increase the size of the bearing itself.SOLUTION: In a free (before press-fit to a housing) state, inner diameter dimensions of an outer ring 1 that are raceway surfaces are identical in an axial direction (a lateral direction of a paper surface), and outer diameter dimensions of the outer ring 1 are different in the axial direction. When the outer ring 1 is press-fitted to the housing, a raceway surface 1c of the outer ring 1 is inclined at a proper angle, and corresponds to the inclination of a support shaft to be the raceway surface of a bearing, and a needle and the raceway surface of the support shaft evenly contact with each other.
