Turntable bearing basic maintenance knowledge

1. After the large-scale slewing bearing installed and put into operation, after 100 hours of continuous operation, it should be fully checked whether the pre-tightening torque of the mounting bolt meets the requirements. The above inspection should be repeated every 500 hours after the cumulative operation.

Second, find problems in time and solve them in time. After the slewing bearing is installed in place, it should be filled with an appropriate amount of grease. When filling the grease, the bearing should be rotated while being added to make the grease evenly distributed.

3. After the slewing bearing has been working for a period of time, some grease will inevitably be lost. Therefore, for normal operation, the slewing bearing should be filled with grease once every 50-100 hours of operation, and the high temperature environment or dust is more. The slewing bearing working under the working condition should be filled with grease once for 30-40 hours.

4. When the slewing bearing is running for 1000 hours, the bearing should be fully maintained. It is necessary to thoroughly clean the bearing. Please remove the bearing seal and clean the internal grease and dirt. It should be cleaned with kerosene or gasoline, and diesel can be used instead. After cleaning, restore the installation and add a proper amount of new grease. When a machine using a slewing bearing needs to be shut down for a long period of time, a sufficient amount of grease must be added to prevent corrosion inside the slewing bearing.

Proper maintenance is critical to extending the life of the bearing, and proper maintenance allows the bearing to operate more reliably.
