02 0820 00 four point contact ball bearings installation instructions

1. Make sure the mounting surface is flat and clean, and free from burrs or

rough edge.

2. The unhardened zone is marked with an “S” on the slewing ring, it must be positioned outside the main load-carrying areas.

3. Commissioning of the slewing ring under sufficient load.

4. Adjust the backlash of gear and recheck it after final tightening of the bearing.

5. Fastening bolts. Place the bearing onto connecting structure and align the screw holes. Screw all the bolts in the holes first and follow the order as shown in diagram when tightening bolts in diagonally opposite sequence. Do not tighten bolts randomly.

6. Check the installation by rotating the assembled bearing arrangement. The torque should not show any excessive variation or “tight spots” during rotation.
