Rolling bearings in the course of a certain impact toughness


Many rolling bearings in the course of the subject will be affected by the impact load, the bearing steel requires a certain degree of toughness, to ensure that the bearing is not damaged due to impact. For bearing a greater impact load bearings such as rolling bearings, railway bearings and other materials required has a relatively high impact toughness and fracture toughness, some of these bearings with bainitic quenching heat treatment process, and some with carburized steel, that is Ensure that these bearings have good impact toughness.
