Precision Universal Joints

Precision universal joints are mechanical components used to transmit torque between two shafts that are not in a straight line, while allowing angular misalignment. Compared with standard universal joints, precision types offer tighter tolerances, reduced backlash, and better rotational concentricity, making them suitable for high-speed, high-accuracy motion systems. Their structure typically includes yokes, a cross pin, and precision-machined bearing sleeves, all engineered for durability and consistent performance.

Precision universal joints are generally classified into single-joint and double-joint types. Single-joint designs are compact and suited for small angular deviations. Double-joint types accommodate larger angles while maintaining a more uniform rotational speed. They are widely used in automation systems, machine tools, optical instruments, inspection devices, and medical equipment where precise, low-backlash torque transmission is essential.
