Hardness is one of the important indexes of rolling bearing

Hardness is one of the important indexes of rolling bearing. And contact fatigue strength, wear resistance, it has close relation with the elastic limit, directly affects the service life of rolling bearing, bearing of hardness is usually based on the mode of axial load and large hardness is one of the important indexes of rolling bearing. And contact fatigue strength, wear resistance, it has close relation with the elastic limit, directly affects the service life of rolling bearings, bearing hardness is usually according to the style and size of axial load, bearing size and wall thickness of the overall situation to decide. With the hardness of the steel rolling bearing to be suitable, too big or too small will affect the service life of the bearing. It is well known that the main failure form of roller bearing is contact fatigue damage, and the wear resistance is poor, or the size is not stable, which makes people lose bearing accuracy; Bearing parts, if the lack of a certain toughness, when under high impact load and would occur due to brittle fracture and lead to the destruction of the bearing. So, must according to the actual circumstances of the bearing and to determine the hardness of bearing damage. For wearability due to fatigue spalling or errands bearing precision loss, bearing parts should choose high hardness; For larger under impact load bearing ( Such as rolling mill bearing, railway bearing and some auto bearing, etc. ) , should decrease the hardness to improve the toughness of the bearing is very necessary.
