ニット。A crown-shaped retainer is interposed between a pair of inner raceways formed on the shaft at intervals in the axial direction and an outer raceway of an outer ring fitted at positions corresponding to the inner raceways on the inner periphery of the housing. A ball is arranged between the bearings and an elastic member is interposed between the outer and outer surfaces for applying a preload to the pair of bearings,
The outer ring of one of the bearings has a counterbore with a maximum inner circumference diameter of S + 2 A spindle unit formed to have a diameter Rd, and characterized in that the outer peripheral side of the cage pocket of the cage is formed as a pressing part for the balls when inserting the balls between the inner and outer raceways.
