INA bearings retainer there are several major causes of damage, respectively, described below:
1, foreign object stuck
Fragmentation of the part or particle-free between may be stuck in the cage and the rollers. Impede the scroll scroll. This results in broken retainer. If he can prevent the large foreign objects INA bearings, despite the heavy load of occasions, cage also safe;
2, speeds exceed design requirements
If the bearing is running faster-than-keeping material can bear, rupture of inertial force causes the retainer. High speed bearings INA manufactured specifically for such occasions;
3, wear
Improper lubrication or hard foreign objects make INA bearing retainer wear. Run most bogey when sliding friction of rolling bearings. But the sliding contact between roller and cage usually cannot be eliminated, so if poor lubrication, retainer to bear the brunt of wear parts. And retainer is made of a softer texture material, so wear is quite fast. Retainer clearance will gradually make cage soon broke down. When hard particles into the INA bearings, also have the same situation occurs;
4, vibration
When INA bearings in vibrating condition, bearing internal forces may cause fatigue cracks at the cage. Gradually, this rift is keeping rupture. To prevent this behavior, INA bearings can be equipped with a special retainer.
