Causes of premature failure of angular contact ball bearings

The reason for premature damage of angular contact ball bearings is no outer ring full roller bearing. Some time ago, someone reported that angular contact ball bearings broke down after a short time of use. So what caused such a result? 1. The equipment is not good (about 16%) when the equipment is used, brute force is used, and hitting the bearing directly with a hammer will cause the largest damage to the bearing, which is the primary cause of deformation. The equipment is not in place, the equipment has errors or is not installed in the bearing position, resulting in too small bearing clearance. The inner and outer rings are not in the middle of the same rotation, resulting in non-concentricity. Suggestion: choose appropriate or professional bearing equipment, and use special equipment to test the end of the equipment. 2. Poor smoothness (about 50%) According to the survey, poor smoothness is one of the primary reasons for premature bearing damage. Including: not adding lubricating agent or lubricating oil in time; not adding lubricating agent or lubricating oil in place; improper selection of lubricating agent or lubricating oil; incorrect lubricating method, etc. Suggestion: choose the correct lubricant or oil, and use the correct lubrication method. 3. Pollution (about 14%) Pollution can also cause premature bearing damage. Pollution refers to sand, metal chips, etc. entering the inside of the bearing. Including: opening the bearing package prematurely before use, causing pollution; not cleaning the working environment during equipment, causing pollution; not cleaning the working environment of the bearing, polluting the working medium, etc. Suggestion: It is best not to unpack the bearing before use; insist on cleaning the equipment environment during equipment, and clean the bearing to be used; strengthen the sealing equipment of the bearing. 4. Fatigue (about 34%) Fatigue damage is a common damage method for bearings. Common causes of fatigue damage may be: bearing overload for a long time; not repaired in time; improper repair; equipment aging and so on.
