How to store the correct slewing ring bearings

slewing ring bearings, it can withstand a large axial load, radial load and overturning moment large bearings. Generally with mounting holes, internal gears or external gears, lubricants holes and sealing devices, which enable the host compact design, guide reliable, and easy to maintain. However, because the user does not pay attention slewing transportation, and other storage, installation and maintenance details, resulting in performance degradation host phenomenon can not be ignored. Slewing rings coated with anti-rust oil at the factory, and with the film wrapped, the packaging rust usually valid for 3-6 months, it should be raised year after inventory grease and check rotation flexibility, not collision and squeeze, not rain, storage should be smooth. It should be stacked flat isolation between slewing ring. Slewing ring generally have lifting holes, you can secure the lifting eyebolts screwed.
