1, the use of brute force equipment; hammer directly hit the bearing damage to the bearing is the biggest cause of deformation.
2. The equipment is not in place; the equipment has errors or is not loaded into the bearing position; the bearing clearance is too small. The inner and outer rings are not in the middle of the same rotation;
Advocate: Select appropriate or professional bearing equipment; equipment should be tested with special equipment.
Second, poor smoothness (about 50%)
According to the survey; poor smoothness is one of the main reasons for the formation of premature bearing damage. The main reasons include: the smoothing agent or smooth oil is not added in time, the smoothing agent or smooth oil is not filled in place, and the smoothing agent or smooth oil is not properly selected. , the smooth method is not correct, etc.
Advocate: Pick the right smoothing agent or smooth oil; use the correct smooth filling method.
Third, pollution (about 14%)
Pollution will also lead to premature bearing damage; pollution refers to sand dust, metal shavings, etc. into the bearing interior. The main reasons include: prematurely open the bearing packaging before use; form pollution, equipment is unsanitary; the formation of pollution, bearing The working environment is unsanitary; the working medium is contaminated.
Advocate: Before use, it is best not to disassemble the packaging of the bearing, and adhere to the sanitation of the equipment environment when the equipment is used; remove the bearing to be used and enhance the sealing equipment of the bearing.
Fourth, tired (about 34%)
Weak damage is a common method of damage to bearings. The common cause of fatigue damage may be: the bearing is overloaded for a long time, not repaired in time, repair is not proper, equipment is aging, etc.
Proposition: Pick the right bearing type; replace the fatigue bearing in time.
