Robot Joint Bearing Housing Assembly

As a core support unit for AGV mobile robots and automated production line joint modules, this assembly achieves precise positioning and load transmission of the rotating shaft through built-in bearings. The main body features a cylindrical cavity structure with a high-precision bearing seat at the center. The top is equipped with an output shaft interface featuring a keyway, while the side walls integrate multiple threaded mounting holes to adapt to external flanges or connectors, ensuring structural stability under frequent start-stop conditions.

The machining focus lies in controlling the coaxiality between the inner bore and outer diameter, as well as maintaining dimensional tolerances on bearing mating surfaces to prevent operational runout and extend service life. For the irregular side cutouts and bottom stepped surfaces, four-axis machining centers are utilized for single-setup machining, guaranteeing positional accuracy across all feature surfaces. Made from high-strength aluminum alloy, the component undergoes T6 heat treatment followed by blue hard anodizing, balancing lightweight requirements with wear and corrosion resistance.

Leveraging our mature non-standard parts manufacturing system at our Changzhou factory, we are equipped with multiple four-axis and five-axis machining centers from brands such as Shenyang Zhongjie and Tuobang. This allows us to efficiently handle the mass production of such complex rotational parts. From raw material cutting to final assembly and inspection, we implement strict quality control throughout the entire process, making it particularly suitable for industrial robot drive module projects with stringent requirements for concentricity, flatness, and appearance consistency.
