Swing Bearing transport, maintenance
1, Swing Bearing must be very careful handling
2, Transportation and storage to the level of placement is appropriate, must be placed in dry storage room.
3, Lifting screw rings is preferred, a standard way, it and do not impact, in particular the collision radial direction
4, Rotary bearing surface topcoat with rust inhibitor, the anti-rust normally for 6 months, for more than 6 months of storage (such as for accessories) should be re-packaged anti-rust or take other storage measures.
Swing Bearing installation:
1, the requirements of mounting brackets
2,Installation and support the general use of tubular structures, aligned with the center wall and the track is better.
3,In order to prevent the rotary bearing partial overload, ensure flexible operation, installation of supporting the shelf should be conducted after all the welding process to eliminate the stress treatment, and the installation plane for machining, the flatness (including an angle of deviation) should be controlled within a certain range.
