Why does the bearing stop working?
As one of the most common components in modern industrial machinery and equipment, bearings connect rotating parts (shafts) and fixed parts (housings) with minimal friction. With bearings, various rotating equipment such as automobiles, aircraft, generators, conveyors, and printing machines can operate smoothly.
For those who frequently work with industrial equipment, it is essential to better understand how bearings work and the causes of their premature failure during operation.
Main Reasons for Bearing Removal
1.Excessive noise
2.Abnormal temperature rise
3.Seizure
4.Recurrent failure
5.Short service life
6.Increased rotational torque
7.Excessive shaft endplay
8.Excessive vibration
Common Causes of Primary Bearing Damage
1.Poor lubrication: Lubrication-related issues may include insufficient lubrication, use of incorrect lubricant, lubricant contaminated with moisture or other fluids, and deterioration of lubricant performance.
2.Lubrication contamination: Contamination-related causes may involve particle intrusion during assembly or maintenance, particle pollution from wear of mechanical components (such as gears), seal failure, and inadequate filtration.
3.Improper bearing application (unsuitable operating conditions)
4.Improper bearing installation (mating issues)
5.Improper handling
