Four series of slewing ring bearings

Slewing ring bearings, a comprehensive load to bear a large bearings,can bear larger axial and radial load and overturning moment at the same time. Slewing ring bearings are generally installed with a hole, internal or external gear lubricants hole and sealing devices, which enable mainframe, design guide is simple, compact structure, easy maintenance.

  Slewing ring bearings have four series, four point contact ball bearing of no tooth type, external gear and the internal gear type ,double row angular contact bearing ,cross cylindrical roller bearing, crossed tapered roller bearing and three row cylindrical roller combined bearing .

  Four point contact ball slewing bearings have higher static load capacity, cross cylinder the roller has a higher dynamic load capability, crossed tapered roller bearing preloaded can make bearing with large supporting rigidity and rotation accuracy, three row cylindrical roller combined bearings due to highly improving the carrying capacity of the bearings, a variety of power by different raceway bearing, so in the same under the condition of stress, the bearing diameter can be greatly reduced.Thus the characteristic make  host more compact is a kind of slewing bearing of high bearing capacity.

  Slewing ring bearings are widely used for hoisting machinery, mining machinery, construction machinery, port machinery, ship machinery ,large rotary device, high precision radar mechanical and missile launchers on the equipment. At the same time,  design according to the specific requirements of users,development and production of various special structure of slewing bearing.
