NB ball splines are designed for mechanical applications
which require both linear motion and torque transmission. The rolling
contact of the balls eliminate backlash and reduce friction, helping
achieve greater 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. It also provides a high degree of geometrical moment of inertia
and high rigidity. This enables long-term, high precision linear
motion.
A wide variety of ball splines are available. Spline nuts are
also available
in variations of cylindrical, flange, and block types. Spline shafts are
available in variations of ground spline, standard spline, and commercial
shafts.
