Maintenance

-Checking mounting bolts
While SOCARE® slewing ring bearings (Slewing Bearing,Slewing Drive) require minimal attention, what little they are given will pay big dividends in long life, high performance, and trouble-free service.
To compensate for possible settling, it is necessary to retighten the bolts to the prescribed torque. This shall be done after no more than 100 hours of operation and without external load applied to the bolt connection
The inspection shall be repeated after every 700 hours in operation or at least every 6 months. The inspection period shall be reduced under special operating conditions. In case of loose bolts, nuts and washers, replace all bolts, nuts and washers with new ones.
-Checking the tilting clearance
Raceway wear leads to increased tilting clearance. It is therefore necessary to check the tilting clearance after 700 operating hours, or at the latest after 6 months.
-Lubrication
Lubrication of the bearing is recommended every 100 operating hours for relatively slow rotating or oscillating applications such as backhoes, excavators, and cranes or as specified by the designer. In more rapidly moving or continuously rotating machinery such as trenchers, borers, and material distributors, the bearing should be lubricated every day, or every 8 hours of round-the-clock service.
-Raceway system
1.Inject grease into all cleaned grease nipples one after the other while rotating the Slewing Ring, until a bead of fresh grease forms at least on one sealing lip or at the bearing gap.
2.Ensure that old grease can flow out of the Slewing Ring freely.
3.If possible continue to rotate the Slewing Ring.
