Rotary classification and application of Slewing bearings

Slewing bearings are extremely important in today's heavy industry large bearing diameter ranging from 10cm to 10 meters, almost all of the large equipment reciprocating circular motion is essential, it is able to withstand a large-scale integrated load bearing, can bear large axial, radial load and overturning moment. Slewing ring bearings are generally installed with a hole, the internal gear or the external gear, lubricants holes and sealing devices, which enable the host compact design, the guide is simple, easy to maintain. Slewing bearings commonly used classification of a single row of five four-point angular contact ball slewing bearings, Single row crossed roller slewing bearing, double-row ball slewing bearing, three-row roller combination slewing bearings and slewing bearings light. Slewing ring bearings are widely used for lifting machinery, mining machinery, construction machinery, port machinery, ship equipment and high-precision radar and missile launchers and other mechanical equipment of large rotary device. But also according to the user's specific requirements and design, development and production of special structures slewing ring bearings.
