The common form of contact fatigue failure is contact fatigue spalling

The main reasons are poor installation, shaft deflection, and low accuracy of journal and housing holes. Take countermeasures to strictly control the manufacturing process. Due to the intrusion of external hard foreign objects, the wear of the cage is aggravated and the abnormal additional load is generated, which may also cause the cage to break.

It should be pointed out that during the manufacturing process of the bearing, the re-inspection of raw materials, the quality control of Wholesale INA Bearing Manufacturers forging and heat treatment, and the control of the processing process can be used to correctly analyze whether the above-mentioned defects exist.

The common form of contact fatigue failure is contact fatigue spalling. Failure of clearance changes During the operation of the rolling bearing, due to the influence of external or internal factors, the original fit clearance is changed, the accuracy is reduced, and even 'seizure' is caused, which is called the clearance change failure. Corrosion failure Some rolling bearings are inevitably exposed to water, water vapor and corrosive media in actual operation, these substances will cause rust and corrosion of rolling bearings. Rust and corrosion The rust and corrosion of the bearing include pit-like rust on the raceway, the surface of the rolling element, and overall rust and corrosion.

When the inclination angle reaches or exceeds the critical state, abnormal sharp wear and peeling may occur early.), improper lubricants, water droplets due to condensation of water vapor, stalls at high temperature and humidity, transportation Poor rust prevention, improper storage condition, improper use, etc. When the bearing is pressed into the larger elliptical housing hole or the two-half separated housing is tightened, the outer ring of the bearing will be elliptical, and the clearance in the minor axis direction will be significantly reduced or even negative clearance.

Although the rolling bearing is small in size and low in cost, once the rolling bearing fails, the loss to the running machinery and the entire production equipment is huge. Bruise The so-called scratches are surface damages that occur on the raceway surface and the rolling surface due to a combination of rolling slippage and micro burns caused by oil film thermal cracking.
