Eliminates Backlash, Reduces Friction

The NB Ball Spline is designed for mechanical applications which require both linear motion and torque transmission. The rolling contact of the balls eliminates backlash and reduces friction, helping you to achieve super precision and reliability.

The spline shaft facilitates additional machining and high accuracy because of a round shaft shape. Since the spline shaft is also machined by cylindrical grinding, it has a high sealing performance and a well-balanced structure that reduces the vibration and noise during rotary motion. Moreover, it has great geometrical moment of inertia and high rigidity. This enables a long-term, high precision linear motion.
