Two common bearing damage phenomena and reason

Phenomenon one: end of the roller and guide the concave flange abrasion reasons and treatment advice: in the end of the roller and guide the concave edges with notch and local color. May be under heavy load, sliding or insufficient lubrication. This damage can choose proper lubricant, that is, the higher viscosity, to avoid the phenomenon of two: the roller and raceway bruises reason and treatment advice: beginning with the roller in the raceway stress area, there are the marks of score and local color. May be a roller in the bearing area, caused by the sudden acceleration. There are two feasible way: one is the replacement of a proper lubricant, viscosity high, Asked 2 it is to reduce the bearing gap phenomenon three: orbital plane with a roller spacing of bruises reason and treatment advice: axial scar as the distribution of the roller spacing. Possible reasons: for cylindrical roller bearing, may be a ring with skew roller installation, for spherical roller bearings, may be a knock when installation or load overload on the incorrect ring. Sufficient lubrication surface; When installation should pay attention to rotate. Install four cylindrical roller bearing can be used to guide sleeve phenomenon: thrust bearing abrasion reasons and handling suggestion: race with Angle of the scratch. May be out of proportion to the load caused by the high rotational speed. Such damage can increase the preloading method to avoid them. If equipped with spring, when installation, please make sure to reach the minimum axial preloading phenomenon 5: the surface abrasion reasons and treatment advice: inner ring inner hole and outer surface is scored and local color. May be a relative bearing outer ring and the bearing chamber caused by the rotation. This damage only intensify car bearing outer ring and the shaft or the bearing chamber to cooperate to stop their relative rotation. Axial braking or clamping phenomenon of bearing outer ring cannot solve this problem 6: surface frustration causes and treatment advice: small and shallow finger, and the destruction of the crystalline form. May be, for example, caused by improper lubrication oil or excessive heat loss caused by the viscosity change, causing the oil film cannot separate contact, there will be a moment of contact surface. Lubrication phenomenon needs to be improved 7: deep corrosion or corrosion reason and treatment advice: colored stripe across race, most present roller spacing distribution. May be the inside of the bearing water or corrosive substances, caused by the surface depressions. Check whether the oil seal is effective, or use a better anti-rust lubricant
