1. The deformation or broken teeth of revolving supporting gears cause stuck or inflexible movement. Corresponding solutions: repair gears and re-weld gears.
2. The sealing system of slewing bearing has some problems, which will cause the entrance of debris, such as stones, sand, etc. to cause stuck or insensitive movement. Corresponding solution: Clean up all the debris.
3. Overload operation makes the motion of slewing support inflexible. Corresponding solution: need to reduce the workload.
4. The position of slewing support is not flat. Corresponding solutions: Platform position needs to be changed to work in a flat position.
5. The lack of lubricating oil in slewing support will result in increased friction and resistance, which will result in insensitive motion. Corresponding solutions: add the same specifications of lubricants or replace all lubricants.
Knowing the reasons and solutions for the inflexibility of slewing bearings, we need not worry about this situation in the future. For users, besides these knowledge, they also need to know the matters needing attention in the use of slewing bearings and related maintenance methods.
