Four-point contact ball slewing bearings can withstand torque loads, both the single row angular contact ball bearings and double row angular contact ball bearings features. Only four-point contact ball bearings in contact to ensure the formation of two normal work. It is generally applied to those of pure axial load or axial load large synthetic loads where contact was two, four point contact ball bearings high speed limit, but also for those high-speed operation of the occasion. Slewing Bearing / Slewing Ring Bearing      Slewing bearing is a kind of special structure of large bearings which can withstand large axial load, radial load and overturning moment, integrating supporting, rotation, transmission, fixed and other functions. Under normal circumstances, slewing bearings have their own mounting holes, lubricants and seals, which can meet various of host need  under different  working conditions; On the other hand, slewing bearings themselves are compact, easy to guide the rotation,easy installation and easy maintenance, so they widely used in material handling equipments, mining machines, construction machinery, port machinery, wind power generation, medical equipments, radar and missile launchers and other large rotating devices. According to different structure, slewing bearing can be divided into the following types:1, the four-point contact ball slewing bearing2, double row different diameter ball slewing bearing3, crossed cylindrical roller slewing bearings4, three-row cylindrical roller combined slewing bearing. 011.75.4000 Dimensions:4226*3772*174 material 50Mn/42CrMo/other
