Industrial robots, as key equipment in high-end manufacturing, are widely used in various fields such as welding, handling, assembly, spraying, and palletizing. The development of industrial robots tends towards lightweight and high precision. Robot bearings must be installed in limited space, with small volume, light weight, high precision, and high rigidity. As one of the key components of industrial robots, industrial robot bearings are suitable for the joint or rotating parts of industrial robots, as well as the rotating parts of robotic arms. Their performance directly affects the motion accuracy, load-bearing capacity, and service life of robots.

Industrial robots require extremely high bearing capacity, precision retention, and reliability for bearings during long-term continuous operations. Shandong Hangmu Precision Bearing Manufacturing Co., Ltd. specializes in the research and development of cross roller bearings. Its main product series include RAU series, CRBT series, RU series, ZK series, CRBH series, etc., with accuracy levels up to P2, P4, P5. It is widely used in key parts of industrial robots such as arms, rotating joints, and mechanical arm rotating parts, ensuring long-term stable operation of robots in welding, handling, assembly and other operations.
