Manufacturing process due to slewing bearing inevitably produce a soft zone, which requires the use and selection of slewing device user to install its software with a reasonable position to improve bearing life. The general principle is to try to be flexible with position mounted slewing small changes in load and carry the force minimum position.
Usually turn on the device with mounting ring soft pitching rotation perpendicular to the surface projection line location, such as loading, or stacker-reclaimer slewing ring soft tape on the device to be installed perpendicular to the centerline of the cantilever cutting through the center of the rotation , which stands on the center of rotation of the left or right side face of the cantilever 90 degree position.
The mechanical design is usually soft belt at this position does not exist slewing roller bearing device maximum force state. The next ring of soft rotary device with the device according to the installation location of the center of gravity of the situation and to determine the rotation angle range. If the rotation angle is about 100 degrees, the maximum rotation center of gravity of the portion above the front, it is recommended to lower ring mounted on the rear of the soft belt, or 180 degree position. If the rotation center of gravity of the section above the front and rear position change position are equal, you can optionally install the next soft belt loop angular position.

Slewing loss and storage
slewing bearing loss factor mainly refers to the use of installation and adjustment, use and maintenance, repair and other maintenance meets the technical requirements. Installation conditions are the primary factors that one of the factors, slewing ring often due to improper installation of the parts of the entire slewing between the force status changes, slewing ring in the abnormal state of operation and losses. According slewing installation, use, maintenance, maintenance of the technical requirements for operation of the rotary bearing to withstand load, speed, temperature, vibration, noise and lubrication condition monitoring and inspection, abnormal should immediately find reasons to be adjusted to normal. Moreover, the quality of the grease and the surrounding medium, and the atmosphere is also very important for analytical testing.
Slewing oiled at the factory and used film wrapped, the packaging rust generally valid 3-6 months. Their storage temperature should be 20 ± 10 ℃, with relative humidity less than 60%, more than valid, it should be timely maintenance. Slewing inventory should be greased after one year, and check its rotation flexibility.
Slewing bearing factory generally fixed on pallets or containers, with a single piece packaging and packaging into groups of two forms. Transport and storage should be kept level, not collision and extrusion, not rain, storage should be smooth. Slewing ring should be stacked flat between isolation.
Slewing lifting holes generally can be screwed into safe lifting eyebolts.
