The process of applying pressure on the Du surface of the inner ring end of the bearing to sleeve it to the bearing stop of the rotating shaft is called cold assembling process. The pressure equipment includes oil (or gas or screw) press, special sleeve, etc. Before assembly, put some lubricating oil on the bearing… Read more Precautions for bearing cold assembly process

Factors affecting the volume of retained austenite
From the composition, original structure to quenching and tempering process, many factors affect the content of retained austenite after quenching and tempering. Quenching cooling rate. Without non martensitic transformation, the slower the cooling rate is, the more the retained austenite content is. For example, the retained austenite content of GCr15 steel quenched at 850 ℃… Read more Factors affecting the volume of retained austenite
