Adopting a classic optimized gothic arch raceway structure, the 02 series features stable four-point contact between precision steel balls and hardened raceway surfaces. This mature structural design enables the slewing bearing to simultaneously withstand complex combined loads, including axial forces, radial forces and dynamic overturning moments. Different from conventional two-point contact bearings, it delivers uniform stress distribution, enhanced structural rigidity and outstanding operational stability during continuous cyclic rotation and alternating load conditions. The refined internal geometric design effectively minimizes rotational vibration, friction loss and mechanical fatigue, ensuring consistent long-term dynamic accuracy and extended service life.

The 02 series adopts a built-in internal gear configuration machined directly on the bearing inner ring, offering unique structural advantages over external gear slewing bearings. The high-precision involute gear teeth are processed with strict tolerance control and professional heat treatment, realizing low backlash, accurate meshing and stable torque transmission. The internal gear layout greatly optimizes assembly space, effectively protects gear teeth from external impact, dust abrasion and environmental corrosion, and simplifies the overall mechanical drive structure. It can directly mesh with standard drive pinions to achieve quiet, efficient and reliable power transmission, perfectly adapting to compact equipment design and high-precision rotary positioning scenarios.
