The cause of early damage of the non-standard bearings

A, improper installation, Accounts for about 16%) 1, use brute force, when installation directly with a hammer percussion non-standard bearings for non-standard bearing damage; Is the main cause of deformation. 2, installation does not reach the designated position, install a deviation or failure to non-standard bearing, non-standard bearing clearance is too small. Inside and outside the circle is not in the same center of rotation, resulting in different heart. Proposal: select the appropriate or professional non-standard bearing installation tools, installed with a special instrument to detect. Second, the poor lubrication ( Accounts for about 50%) Is caused by poor lubrication of non-standard bearing one of the leading causes of premature failure. Main reasons including: failure to refill lubricant or lubricating oil; Lubricant or lubricating oil filling in place; Lubricant or improper lubricant selection; Lubrication method is not correct, and so on. Suggestion: to select the correct lubricant or lubricating oil, use the correct lubrication filling way. Third, pollution, Accounts for about 14%) Pollution can also cause premature failure of non-standard bearing, pollution is refers to the dust, metal scraps into the non-standard bearings inside. Main causes include: early open before use non-standard bearing packing, cause pollution; When installation work environment is not clean, cause pollution; Non-standard bearings working environment is not clean, working medium pollution, etc. Suggestion: before use it is best not to unpack the non-standard bearing; Keep the installation environment clean, when installation to use non-standard bearings for cleaning; Strengthen the non-standard bearing sealing device.
