How to properly store bearing

How to properly store bearing

  1, to keep the original packaging, not arbitrarily open, and if found damaged packaging shall be open carefully cleaned and re-oiled packaging.

2, relative humidity not exceed 60% of the storage compartment, the temperature difference is not too large, bearing in original packaging can be stored for several years. Sealed bearings or bearings with dust cover, after long-term storage, the lubricating properties of the bearing is filled with grease may be reduced.

3, anti-vibration and storeroom should also be shaken. Bearings not stored in the original packaging should be kept strictly forbidden bearing and corrosive things together, to protect against corrosion and contamination.

4, only flat when storing large rolling bearing, inner and outer rings of the best side all be supported. If stored upright, since the inner and outer rings and rolling components heavier, and inner and outer rings are relatively thin wall, it may cause permanent deformation.

Cause of abnormal noise bearing

      1. Grease impurities; 2. insufficient lubrication (oil level is too low, save improper seal leakage by oil or grease); 3. bearing clearance is too small or too large (plant issues); 4. Bearing mixed impurities such as sand or soot, played abrasive effect; 5. bearing mixed with water, acids and other dirt or paint, play a corrosive effect; 6. bearing housing bore clamp is flat (bad seat hole roundness or housing bore distortion is not straight); 7. bottom surface of the horn bearing uneven (resulting in deformation of the housing bore even bearing cracks); 8. bearing hole with debris (residual chips, dust, etc.); 9. eccentric ring (across adjacent parts and friction); 10. subject to additional load bearing (bearing by the axial limp tight, or a shaft has two fixed end bearings); with 11 bearings and shaft too loose (smaller diameter shaft or adapter sleeve not tighten); 12. The bearing clearance is too small, too tight (tight sets tightened too overdone) rotates;
