Why does the slewing support freeze during use?


Why does the slewing bearing support get stuck and abnormal noises during use?


1 If it is used for a long time, the contact points of the steel balls may be worn out. The way to solve this problem is to replace the steel balls.

2. If it hasn't been used for a long time, the clearance is generally a bit large, which requires adjustment of the clearance. 

The smaller the clearance, the higher the precision of the slewing support. Different products have different clearance requirements. 

Some require negative clearance, some have zero clearance. In addition, if the product requires flexible rotation, 

some larger clearances are required. Meet the demand.

3. If there is a pinion driven by a positive and negative pulling, there will be problems with the meshing. 

The meshing of the bearing and the teeth must be correct, the slewing support and the matching gear must have the same modulus, 

and the displacement coefficient must be changed differently to be able to mesh normally.

4. There are foreign objects in the raceway, which can easily cause jams. If jams and abnormal noises occur,

 the method is to disassemble the bearings for investigation.
