Slewing Bearing

Specifications

  LYJW specializes in various slewing bearings and wind turbine bearings, the process range covers φ500—φ7000mm. Products consist of 4-point contact ball slewing bearing, double-row different diameter ball slewing bearing, cross roller slewing bearing and roller & ball combination slewing bearing. They are widely used in wind power industry, port equipments, heavy machinery, metallurgical industry and radar equipments.
Slewing bearings
    Usually, slewing bearings have a special structure and large size, that they can simultaneously take load from axial, radial directions, as well as overturning moment. These bearings are designed with mounting holes, lubricating holes and sealing devices, which can meet different requirements under various applications. Besides, slewing bearings also have other characteristics, like compact structure, easy rotating guide and maintenance.
Structural classifications
    Commonly used structures include single/double row four points contact ball, double row angular contact thrust ball, crossed cylindrical/tapered roller, triple row cylindrical roller, ball and cylindrical roller combined structure, and etc. All these structures mentioned here can be designed with gear and without gear. There are two types for slewing bearings with gear, with inner gear and external gear.
Loading capacity
   Slewing bearings can be designed into different structures to meet the requirements under various loading conditions.
