Turntable bearing structure, as follows:

Wheel bearings, a can withstand the special structure of the large axial load, radial load and overturning moment load a large bearing.

Normal ci rcumstances, the turntable bearing itself with the mounting holes, lubricants hole and sealing device to meet a variety of working conditions, the different needs of various types of host; the other hand, wheel bearings with compact structure, and guide rotation, easy installation and easy maintenance and so on, are widely used for hoisting and conveying machinery, metallurgical machinery, mining machinery, construction machinery, port machinery and automated assembly line and other medium and large rotary device. slewing bearing

PRS Germany turntable bearings depending on the structure can be divided into different forms of the structure of the four-point contact ball slewing bearing, double Reducing ball slewing bearings, cross cylindrical roller slewing bearings and three-row cylindrical roller combination of turntable bearings, etc.; the above type of bearing their toothed t oothed distribution site is divided into the different structure of the toothless, external tooth and tooth type. slewing bearing manufacturers

The turntable bearings depending on the structural characteristics, respectively, to meet the needs of the host under various load conditions. Among them, four point contact ball slewing bearings with high dynamic load capacity, cross-cylindrical roller slewing bearing has a high static load capacity, the combination of the three-row cylindrical roller slewing bearings to improve the carrying capacity of lead bearing the height direction various loads, respectively, to bear by the raceway and roller group, under the same loading conditions, the diameter of the bearing can be greatly reduced, and thus has a more compact so that the host, is a high carrying capacity turntable bearings. the roller bearing company
