    摘要： An inner race 5 is retained by a crimped portion 30, so that a pre-load is applied to rolling elements 6. A bearing unit for wheel support 1 is connected to a constant velocity joint 2 through tightening of a nut 24. By regulating the tightening force of the nut 24, at the area of contact between the inside end of the crimped portion 30 and the outside end of the outer ring of the constant velocity joint 14, the load per unit length is controlled up to 125 N/mm, or the surface pressure is controlled up to 1.5×108 Pa. Consequently, a bearing unit for wheel support is realized at a low cost with the pre-load securely applied, preventing unpleasant noise from occurring during operation, and preventing play due to plastic deformation.

    摘要： A wheel drive unit is provided to comprise a bearing unit 3c for wheel drive which is light in weight and low in cost. The components constituting the bearing unit 3c for wheel drive have optimum properties to secure the durability thereof. Of the components constituting the bearing unit 3c for wheel drive, the portions indicated by a diagonal grid harching are quench-hardened with the other portions being not quench-hardened and left as they are, whereby the rolling fatigue life and wear-resistance of the components are improved and cracking is prevented.

    摘要： A constant velocity joint having an inner race, an outer race provided along a periphery of the inner race, a cage sandwiched in between the inner race, the outer race, and balls. A crossing angle between a central axis of the inner race and a central axis of the outer race is bisected, and the balls are disposed within a bisection plane orthogonal to a plane including these two central axes. If a ratio tc/Da is set to rt, there is satisfied a relationship such as: (0.054/rt)·Da≦w≦(0.16/rt)·Da where Da is the major diameter of each ball, w is the circumference-directional width of each of the column members existing between the pockets adjacent to each other in the circumferential direction with respect to the cage, and tc is the diameter-directional thickness of each of the column members of the cage.
