1. Thin cross-section slewing bearing with equal ring height and mounting height.
2. Support radial, axial loads, and moment loads at the same time.
3. Surface black oxide treated, provide good anti-rust ability, and extend bearings service life.
4. Processed with high precision CNC and grinding finish, which enable bearings to have less friction, higher rotation precision, and longer service life.
5. BRS only select high-quality raw material, which can ensure bearings hardness and wear resistance.
6. Specially designed lubricating system and sealing method, make sure bearings can operate under severe working environment.
7. Customized mounting holes, easy to install and remove.
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 the final tightening of the bearing.
5. Fastening bolts. Place the bearing onto the connecting structure and align the screw holes. Screw all the bolts in the holes first and follow the order as shown in the diagram when tightening bolts in the 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.
