It can be solved by proper preloading, improving the lubricant and lubrication method, and improving the accuracy of the shaft and bearing box. The main cause of overload is the sudden failure of the host or improper installation. Electric current corrosion The so-called galvanic corrosion refers to when the current flows in the contact part of the rotating bearing ring and the rolling element, sparks are emitted through the thin lubricating oil film, and local melting and unevenness of the surface appear.

Under the action of load, the inner ring rotates to produce circumferential peeling marks, and the outer ring only produces peeling marks at symmetrical positions in the minor axis direction. Rust and corrosion of rolling bearings will cause pit-like rust, pear-like rust on the surface of the rings and rolling elements, as well as pit-like rust with the same interval between the rolling elements, overall rust and corrosion. The cause is that the bearing is not installed in place or the axial overload is sudden during operation.

The solution can be by improving the lubricant or improving the lubrication method, enhancing the sealing mechanism and so on. As the spalling expands, the spalled foreign matter enters the cage pockets, causing the cage to block operation and generate additional loads, which intensifies the wear of the cage.Poor lubrication mainly means that the bearing is running in an oil-lean state, which is easy to Wholesale Wheel Bearings suppliers form adhesive wear and deteriorate the working surface.

When the lubrication conditions are severely deteriorated, local friction generates heat, which can easily cause local deformation of the friction surface and friction microscopic welding. The main ones are: the intrusion of water and corrosive substances (paint, gas, etc. Stuck The so-called seizure is a surface damage caused by a collection of minute burns on the part of the sliding surface damage.

Due to the gradual expansion of the exfoliation surface, it will slowly expand to the deep layer, forming deep exfoliation. Contact fatigue spalling occurs on the working surface of the bearing and is often accompanied by fatigue cracks. When the external load exceeds the strength limit of the material and the part breaks, it is called overload fracture.
