ABSTRACT:
The end surface 2e of the press-fit portion 2c of the axle 2 is machined with high precision to serve as a reference surface for measuring the negative bearing clearance upon completion of the assembly. The inner ring 3 is press-fitted on the press-fit portion 2c of the axle 2 and is fixed in position by the nut 6 screwed on the threaded portion 2d of the axle 2. In this axle bearing assembly, the inner ring 3 abuts against the shoulder portion 2d of the axle 2 with no clearance defined therebetween, and the negative bearing clearance is assured.
