The core structural advantage lies in its unique crossed roller arrangement. Cylindrical rollers are arranged alternately at 90 degrees inside the raceway, forming a stable linear contact system with precision-hardened raceway surfaces. This special layout enables the bearing to comprehensively bear axial loads, radial loads and overturning moments from multiple directions. Compared with conventional ball slewing bearings, the linear contact design features smaller deformation, higher rigidity and stronger impact resistance. It effectively reduces rotational clearance and running jitter, maintaining consistent rotary accuracy even during long-term repeated start-stop operation and variable load fluctuations.

Designed with external involute gear teeth on the outer ring, the bearing integrates load-bearing and driving functions into one unit. The externally exposed gear structure allows direct meshing with driving pinions, bringing simple assembly, intuitive transmission structure and convenient daily inspection and maintenance. After fine machining and standardized heat treatment, the gear teeth achieve uniform tooth profile, low backlash and outstanding wear resistance, ensuring smooth torque transmission and accurate angle positioning during continuous equipment operation.
