6. Maintenance of slewing support bearings (Notes for slewing type)
After the slewing bearing installed and put into operation for 100 hours of continuous operation, it should be fully checked whether the pre-tightening torque of the mounting bolts meets the requirements.
If required, repeat the above inspection every 500 hours of continuous operation. When the slewing bearing is installed, it has been filled with an appropriate amount of grease.
After the bearing works for a period of time, it will inevitably lose a part of the grease, so every interval of the slewing bearing in normal operation is necessary.
