Slewing Bearing Classification
The rotary bearing is a large bearing capable of withstanding the combined load, which can withstand a large axial, radial load and overturning moment. Rotary support bearing usually has mounting hole, internal gear or outer gear, lubricating oil hole and sealing device, so that the main engine design is compact, easy to guide and easy to maintain. Slewing bearing presence of tooth, tooth and tooth in the four-point contact ball bearing, double row angular contact ball bearing, crossed cylindrical roller bearing, crossed tapered roller bearing and three composite bearings, four row cylindrical roller series, including four-point contact ball bearing has high static load capacity, crossed cylindrical roller with high load capacity, preloaded can make crossed tapered roller bearing bearing has great support stiffness and the rotation accuracy, three rows of cylindrical roller bearing combination height because of the increase to the bearing capacity of bearing, all kinds of power respectively by different race to bear, so under the same stress distribution, the bearing diameter can be significantly reduced, thus make the characteristics of the host more compact is a kind of high bearing capacity of slewing ring bearings. Slewing bearings are widely used in hoisting machinery, mining machinery, construction machinery, port machinery, ship machinery and mechanical precision radar and missile launcher equipment such as large rotary device. It can also design, develop and produce various special structure rotary bearing bearings according to user's specific requirements.
