1. The mounting bolts are loose, causing shaking during work. In case of shaking when the slewing bearing is working, firstly check all the inner and outer ring mounting bolts immediately. Check for looseness and tighten as required.

2. The rigidity of the steel structure supporting the slewing bearing is not enough, and elastic deformation occurs during loading, which causes the slewing bearing to shake as a whole, and increases the strength of the steel structure supporting the slewing bearing by 14 times.

3. Check whether the operation is overloaded. Overloading will also cause the slewing bearing to shake. Therefore, it is necessary to operate in strict accordance with the regulations.

4.Long-term overload operation will cause the raceway to collapse and the gap is too large. If such a situation occurs, please notify the after-sales service of the slewing bearing to make adjustments to ensure the normal use of the slewing bearing.
