Ball Spline

説明

Ball Spline

– High-Precision Linear & Rotary Motion Component for Robotics

    その Ball Spline, a high-performance motion component designed to transmit torque while enabling smooth linear movement. Combining the functions of a linear guide and a spline shaft, the ball spline allows simultaneous linear motion and rotational torque transmission, making it ideal for advanced robotic mechanisms and precision machinery.

Engineered with a recirculating ball structure, this system ensures ultra-low friction, high rigidity, and exceptional positioning accuracy. The ball grooves on the shaft and nut are precision-ground to guarantee stable motion, minimal backlash, and long service life—even under high-speed and high-load conditions.

Designed for compact integration and high efficiency, ball splines are widely used in robotics, automation equipment, and high-precision industrial systems where both linear and rotary motion are required.
