Bearing chamfering effect

Bearing chamfering effect

1. Bearing steel must be chamfered during rough machining before heat treatment. This plays a very important role in releasing stress during heat treatment of the material, redistributing the internal organizational structure, making cracks less likely to occur, and reducing deformation. Chamfering can solve the problem of stress concentration.

2. Chamfer and remove burrs so that the product is not sharp and will not cut the user.

3. It plays a guiding and positioning role during assembly.

Usually the outer chamfer of the outer ring of the bearing and the inner chamfer of the inner ring are rounded corners. In addition to effectively avoiding contact stress, the most important thing is to facilitate installation. Rounded corners ensure a good transitional fit.

Especially during the bearing process, the matching positioning surface of the shaft and the shaft hole, that is, the shaft shoulder and the bearing seat shoulder part, the chamfer size of this part directly affects whether the bearing can be installed correctly.
