Slewing ring bearing, also called slewing bearing, is a bearing that can bear large axial load, radial load and overturning moment. Slewing bearings generally have installation holes, inner teeth, outside teeth, lubricants holes and sealing devices, which enable the main frame structural compact, guide reliable, and easy to maintain. Slewing bearings are divided into various specifications including single-row ball slewing bearings with outer teeth or inner teeth, or without teeth, single-row cross roller slewing bearings, double-row different diameter balls slewing bearings, and three-row roller slewing bearings etc, of which, single-row ball slewing bearings have higher static load capacity; while single-row cross roller slewing bearings have higher dynamic load capacity. Slewing bearings are widely used for lifting machinery, excavating machinery, construction machinery, port machinery and ship machinery, as well as other larger rotary devices, such as high-precision radar and missile launchers.
