Installation Features of slewing bearing
Before the slewing(turntable) bearing is installed, the installation surface of the host must be inspected. The support should have sufficient strength, the connection surface should be machined, and the surface should be flat 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.
The ferrule of the slewing(turntable) bearing has a hardened soft band area. This is marked "S" on the end face of the ferrule. When installing, the position of the soft band should be placed in the non-load area or the non-constant load area (the plug hole is always located in the soft Belt).
When installing slewing(turntable) bearings, first perform radial positioning, tighten the mounting bolts crosswise, and check the bearing rotation. There should be sufficient pre-tightening force when tightening the bolt, and its pre-tightening force should be 70% of the yield limit of the bolt material. Mounting bolts should be equipped with tempered flat washers. Spring washers are strictly prohibited.
