Kaixuan Slewing Bearing Installation Features

Before each set of Kaixuan slewing bearing is installed, it is necessary to inspect the mounting surface of the main machine, and the supporting piece shall have sufficient rigidity. The connecting surface shall be machined and the surface shall be smooth and free of debris and burrs. For those that cannot be machined to achieve the required flatness, special plastics with high injection strength can be used as fillers to ensure the accuracy of the mounting plane and to reduce vibration.

Kai Xuan slewing bearing rings have quenched soft band, which are marked with “S” on the end face of the ring. When installing, the soft band should be placed in the non-loaded area or non-recurrent area (the plug hole is always Located in a soft band).

When installing the slewing bearing, radial positioning should be performed first, cross-tighten the mounting bolts, and check the rotation of the bearing. When tightening the bolt, there should be enough pre-tightening force, and the pre-tightening force should be 70% of the yield limit of the bolt material. The installation bolts should be equipped with flat washers and spring washers are strictly prohibited. The fastening bolts of the slewing ring bearings must meet the requirements for pre-loading during installation. The pre-loading of different bolt diameters requires detailed values!
