KOYO bearing cage damage

Everyone should know the role of the KOYO bearing cage. I will not go into details here. Today I will introduce you to the damage of the bearing cage. Under what circumstances will it be damaged? How to prevent it? This requires us to master and learn.

The quality of KOYO bearings. During the dismantling of the bearing housing, it is firstly checked whether the lubricating grease has deteriorated, agglomerated, and impurities. This is an important basis for judging the cause of bearing damage. Second, check the bearing for bite and wear; check the bearing inner and outer rings, rolling elements, cage surface finish and whether there are cracks, rust, peeling, pits, hot discoloration defects such as measuring the bearing clearance is excessive; check the sleeve With or without wear pit peeling If the above situation should replace the new bearing.

KOYO bearing cooperation. When the bearing is mounted, the inner diameter of the bearing and the fit of the shaft, the outer diameter and the housing are very important. When the fitting is too loose, the mating surface will produce a relative slip called a creep. Creep, once created, will damage the shaft or housing on wear mating surfaces and wear powder can invade the bearing interior causing heat, vibration, and damage. If the interference is too large, the external diameter of the outer ring becomes smaller or the inner diameter of the inner ring becomes larger, which reduces the internal clearance of the KOYO bearing. In order to select the fit for the purpose of use, the nature of the bearing load, the size, the temperature conditions, and the various conditions of rotation of the inner ring outer ring should be taken into account.

After it is damaged, it will be deformed, broken, worn, etc., and the main column will be damaged. Deformation of the face. Recessed surface wear. The wear of the guide surface.

The main causes of damage are:

1, poor installation (non-linear bearing).

2, bad use. Large moment load. Shock, vibration. The speed is too large, rapid acceleration and deceleration. Poor lubrication. The temperature rises.

So to take some measures for this, first check the installation method. Check the load, rotation and temperature conditions. Reduce vibration. Correct cage selection. Then change the lubricant and lubrication method. It is best to have relevant professionals to operate.
