First, the equipment is not appropriate (about 16%)
1. Use brute force when equipment is used; directly hitting the bearing with a hammer will cause the greatest damage to the bearing, which is the primary 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 36%)
According to the survey; poor smoothness is one of the primary reasons for the formation of premature bearing damage. The main reasons include: no smoothing agent or smooth oil is added in time, smoothing agent or smooth oil is not filled in place, 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 dust, metal scraps, etc. into the bearing interior. The primary reason is: 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%)
Weakness damage is a common method of damage to bearings. The common cause of fatigue damage may be: excessive bearing overload, no timely repair, improper repair, equipment aging, etc.
Proposition: Pick the right bearing type; replace the fatigue bearing in time.
The above are the most common reasons for the early damage of the bearing. The reason for the early damage of the bearing is multi-faceted; the above is the primary reason for thinking; sometimes it may be the reason for the induction. If the bearing is selected correctly; the equipment method is in place; the smooth method And the smoothing agent is selected correctly; the bearing is able to work normally for very often.
