Why premature failure of imported bearings First, the improper installation of imported bearings (about 16%) 1, the use of imported bearings in the installation of brute force, with a direct impact on the bearing with a hammer bearing damage to the bearings; is caused by the deformation of the imported bearings main reason. 2, the installation of imported bearings is not in place, the installation of a deviation or not installed in the bearing, resulting in bearing clearance is too small. Inside and outside the ring is not in the same center of rotation, resulting in different hearts. Recommendation: Choose the appropriate or professional bearing installation tools, installation is completed to use special equipment testing. Second, poor lubrication of imported bearings (about 50%) According to the survey, poor lubrication is one of the main causes of premature bearing damage. The main reasons include: Failure to replenish lubricants or lubricants in time; non-filling of lubricants or lubricants; improper lubricant or lubricant selection; incorrect lubrication methods, etc. Recommendation: Choose the correct lubricant or lubricant and use the correct lubrication method. Third, the pollution of imported bearings (about 14%) pollution can lead to premature bearing damage. Pollution refers to the dust, metal debris into the bearing inside. The main reasons include: pre-use to open bearing packaging premature, causing pollution; installation of the working environment is not clean, causing pollution; bearing the working environment is not clean, the working medium pollution. Recommendations: It is best not to open before using the imported bearings packaging; installation to keep the installation environment clean, the bearings to be used to clean; enhance the bearing seal.
