Cage plays an equidistance in import bearings rolling bearing isolation and prevent fall roller, roller guide and drive roller rotation.
NMB rolling bearing cage can be divided into punching cage and entity cage.
Rolling bearings NMB at work, heat and wear caused by sliding friction bearing, especially under the condition of high speed, due to the effect of centrifugal force, accelerate the friction and wear with fever, a bracket will be caused serious burns and fracture, the bearing cannot be used properly.
Cage damaged occupy large proportion in the bearing failure modes.
In the failure reasons of cage, cage material quality is one of the main reasons.
Rolling bearing in the work, caused by sliding friction NMB bearing heat and wear and tear, in the process of operation, due to the effect of centrifugal force, accelerate the friction and wear with fever, a bracket will be caused serious burns and fracture, the bearing cannot be used properly.
Cage damaged occupy large proportion in the bearing failure modes.
Affect the copper spherical roller bearing cage is the main reason of the damaged: (
1)
Cage strength is not enough,
2)
Maintains a material is not pure, impurities (
3)
Keep the rack installation is not correct,
4)
Cage pocket hole is too large, cause skew roller, extrusion damage cage measures to prevent damage of cage can from bearing product design, manufacture, installation and so on various aspects to consider.
And see if it was damaged, often advised to maintain frame, the thickness of the beam size is too thin.
