Generally speaking, bearings in reasonable working conditions cage will not be damaged, but in the daily production of the wrong operation will reduce the bearing cage life, we look at the following, prompting bearing cage fracture causes. 1. bearing lubrication problem Bearing operation in a poor oil state, easy to form a sticky wear, so that the work surface state deterioration, sticky wear generated by the tear easy to enter the cage, so that the cage generated abnormal load, may cause the cage fracture. 2. bearing creep phenomenon Creep refers to the sliding phenomenon of the collar, in the case of insufficient interference with the surface, due to sliding and the load point to move in the surrounding direction, resulting in the collar relative to the shaft or shell to the circumferential direction position deviation phenomenon. 3. Abnormal load of bearing cage The installation is not in place, tilt, interference is too large, etc. easy to cause clearance reduction, intensify friction heat, surface softening, premature abnormal spalling, with the expansion of spalling, spalling foreign body into the cage pocket hole, resulting in cage running block and generate additional load, intensify the cage wear, so the deterioration of the cycle of action, it may cause the cage fracture. 4. bearing cage material defects Cracks, large foreign metal inclusions, shrinkage, bubbles and riveting defects lack of nails, pad nails or two halves of the cage surface gaps, serious riveting injuries may cause the cage fracture. 5. bearing hard foreign body intrusion The intrusion of foreign hard foreign body or other impurity things, intensify the wear of the cage. We understand the causes of bearing cage fracture, in the future use of imported bearings to try to avoid these problems, to ensure that the equipment can operate normally.  

We have rich experience on precision bearing manufacturing and are ranked NO.1 in China and NO.3 all over the world.

We can tailor the overall solution for the use of precision bearings.
