NXR-30-522 Custom Crossed Roller Slewing Bearing Detail Specifications:

NXR-30-522 Crossed Roller Slewing Bearing Features:

1. Single row crossed cylindrical roller slewing bearing with split inner ring and solid one-piece outer ring. Its structure is similar to XR crossed tapered roller bearing.
2. Accommodate radial, axial loads and tilting moment.
3. Processed with high precision CNC and grinding finish. BRS crossed roller slewing bearings can provide high dimensional accuracy and rotational accuracy.
4. BRS only select high quality raw material, which can ensure bearings hardness and wear resistance.
5. Specially designed lubricating system and sealing method, make sure bearings can operate under severe working enviorenment.
6. Customized mounting holes, easy to install and remove.

BRS Crossed Roller Slewing Bearing  NXR-30-522 Mounting 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.
