1. Custom design four point contact ball slewing bearing with external gear. With mounting holes on both inner and outer ring.
2. With 3.68inch mounting height, provide extremely high loading capacity, and resistant to impact loads and tilting moment.
3. All bearing surface including gear teeth after grinding finish. Make sure BRS-EQ652 slewing rings high dimensional accuracy and rotational accuracy.
4. BRS only select high quality raw material, which can ensure bearings hardness and wear resistance.
5. Hardened external gear teeth, makes bearing more reliable and duarable.
6. 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 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.
