The out of service of the mining bearing

The reasons for the out of service of the mining bearing are generally classified as fracture and wear.

The main reasons for the fracture of the mining bearing are classified as defect and overload of it. When the load from the outside exceeds the limitation that the material could suffer, the components of the mining bearing may fracture, and that is called overload fracture. The overload fracture is mainly caused by the gusty fault or incorrect installation of the mining bearing.

When the defects for the components of the mining bearing, such as little crack, bubble, sundries, shrinkage cavity and burn, are shocked by the overload, it could also cause fracture of the mining bearing, and that is called defect fracture.

There are also many cases of the worn fracture. The worn fracture of the mining bearing mainly refers to the abrasion by the hard particles from the outside to the working surface of the mining bearing, and the hard particles would scratch the surface of the mining bearing. The metal in the surface may even melt if the scratch is serious and cause the adherence. Slight adherence wearing is called scratch, and serious adherence wearing is called occlusion.
