PROBLEM TO BE SOLVED: To provide a bearing unit capable of facilitating assembly and obtaining a stable pre-load.SOLUTION: In a bearing unit 1, to both sides in an axial direction of the inner peripheral surface of a housing 8, a snap ring 20 for positioning an outer ring 11 of a pair of angular ball bearings 10 in the axial direction is attached. Also, by press-fitting and fixing each inner ring 12 to a shaft member 2, a pre-load is imparted to the pair of angular ball bearings 10 in a back-to-back combined manner.SELECTED DRAWING: Figure 1 |
