The robotics industry is an emerging sector, and smart manufacturing is one of the cornerstones of Industry 4.0. The stable and precise operation required in industrial robotics relies heavily on the support of precision robot bearings. Robot bearings are a specialized type of bearing with unique structural designs and performance requirements;其中，柔性轴承、十字轴承-roller bearings, and tapered roller bearings are used in robots, gear reducers, drive motors, and other components. Application areas include RV reducers, harmonic reducers, and robot bodies.
