1. The type of smooth oil or smooth grease is not correct, /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
2. Sleek lack (oil level is too low; oil or grease is leaking through the seal),
3. The clearance of the bearing is too much. The bearing is mixed with impurities such as sand carbon particles; it acts as an abrasive.
5. Water is mixed into the bearing; dirt such as acid or paint; it has a corrosive effect.
6. The bearing is flattened by the seat hole (the roundness of the seat hole is not good; or the hole is not straight),
7. The horn of the bottom of the bearing housing is not flat (causing the deformation of the seat hole and even the crack of the bearing housing),
8. There are debris in the housing bore (residues are left; dust particles, etc.)
9. The seal is too painful (touching adjacent parts and causing conflicts),
10. The bearing is subjected to a rated load (the bearing is axially tightened; or there are two fixed end bearings on one shaft),
11. The cooperation between the bearing and the shaft is too loose (the diameter of the shaft is too small or the adapter sleeve is not tightened),
12. The clearance of the bearing is too much. The bearing is noisy (the end of the roller or the ball is slipping),
14. The thermal elongation of the shaft is too large (the bearing is subjected to static and axial load);
15. The shoulder is too large (the seal of the bearing is encountered and the conflict occurs)
16. The shoulder of the seat hole is too large (the seal of the bearing is misinterpreted),
17. The gap of the labyrinth seal is too large. ㄓ胫岱(5) Σ18. The tortuous turns of the lock washer (which hits the bearing and conflicts)
19. The orientation of the oil slinger is not suitable (the flange cover is encountered and the conflict occurs).
20. There is a crater on the steel ball or roller (the hammer is used to hit the bearing when the device is installed),
twenty one. The bearing is noisy (with external source disturbance)
twenty two. The bearing is discolored and deformed by heat (formed by the spray gun to disassemble the bearing),
twenty three. The shaft is too thick to make the practice cooperation too tight (to form a bearing temperature too high or a noisy noise),
twenty four. The diameter of the seat hole is biased. The diameter of the bearing housing hole is too large; the practice cooperation is too loose (the bearing temperature is too high - the outer ring is slipping),
26. The bearing housing hole becomes larger (the housing hole of the non-ferrous metal is enlarged; or it becomes larger due to thermal expansion),
27. The bearing is noisy (the bearing has fretting abrasion).
