How is the quality of Linfen slewing bearing 133.40.3150.402?

Linfen slewing bearing... 3. How is the quality! / - When installing the slewing bearing (slewing bearing), you should first perform radial positioning, cross-tighten the mounting bolts, and check the rotation of the bearing. In order to ensure smooth bearing transmission, the gear meshing should be checked before the mounting bolts are tightened. Sufficient pre-tightening force should be used when tightening bolts, and the pre-tightening force should be the yield limit of the bolt material. Mounting bolts should be equipped with quenched and tempered flat washers, and spring washers are strictly prohibited. After the slewing bearing (slewing bearing) is installed and put into operation, after several hours of continuous operation, a comprehensive check should be made to see if the pretightening torque of the mounting bolts meets the requirements. The above inspection should be repeated every hour of continuous operation.
