Some of the host construction machinery in harsh conditions, in order to improve the slewing bearing gear strength, gear hardness, gear wear resistance and gear toughness, we usually take the slewing ring gear teeth surface quenching process, otherwise the slewing ring gear will wear resistance, broken teeth and other failure problems. But after tooth quenching treatment, there will be deformation, gear tooth deviation usually hit the design requirements, in order to ensure that the standard, we usually use slewing ring.

On the basis of the basic crossed roller slewing bearings, many structural differences in the crossed roller slewing bearings are derived, so that they can be used for different requirements of the occasion. From the general category, it can be divided into: basic crossed roller slewing bearings, high rigidity crossed roller slewing bearings, ultra-thin crossed roller slewing bearings; 

without the mounting holes on both inner ring and outer ring, its requires a presser flange and housing for the installation. In addition, because it has an integrated inner/outer ring structure and is equipped with washers, the installation has little impact on its performance, which can achieve the stable rotation accuracy and torque. This series bearing can be used in the rotation areas of both outer ring and inner ring while dimensions of the bearing are smaller.

It has smaller sectional dimensions. Its outer ring is separable while the inner ring is integrated with the main body through three fixed rings. Since the inner ring and outer ring do not have the mounting holes, its requires a presser .
