Cage of rolling bearing fault belongs to the occasional non-normal failure mode, we come from the following five aspects analysis of Timken bearing cage fracture cause. 　　
1, the issue of poor lubrication of rolling bearings: operation of rolling bearings in a lean, easy to form adhesive wear, surface deterioration, adhesive wear tore into cages, cages produce an exception loading, it is possible to keep breaking. 　　
2, the creep of rolling bearings: creep sliding phenomenon of rings, in the case of lack of mating surfaces of interference, due to sliding of the load to move around, ring shaft or casing circumference of location deviation. 　　
3 rolling bearing cage materials: crack, hetero metal inclusions and shrinkage cavity blocks, bubble and riveting defects short nails, pads nail or half cage with gaps, serious damage may cause, such as cage fracture. 　　
4, and scroll bearing maintained frame exception load: installed does not in place, and tilt, and had Ying volume had large, easy caused tour gap reduced, increased friction health hot, surface softened, premature appears exception peeling, as peeling of extended, peeling foreign body entered maintained frame Pocket Hole in the, led to maintained frame running block and produced attached load, increased has maintained frame of wear, so deteriorated of cycle role, will may caused maintained frame fracture. 　　
5, Timken bearings hard foreign body penetrated foreign hard foreign body penetration of retainer wear with the exception of additional load, may also cause the cage fracture
