he NB BALL SPLINE consists of a spline shaft with raceway grooves and a spline nut. The spline nut consists of an outer cylinder (main body), retainer, side rings, and ball elements that are designed and manufactured to achieve a reliably smooth motion.

High Load Capacity and Long Travel Life

The raceway grooves are machined to a radius close to that of the ball elements. The large ball contact area results in high load capacity and long travel life.

Ease of Additional Custom Machining

Since a round shaft with raceway grooves is used, NB BALL SPLINE shafts can be machined easily to customized specifications.


Wide Variety of Configurations

Spline shaft sizes with diameters from 4mm to 100mm are available. Several types of spline nut are available: cylindrical types (SSP/SSPM), flange types (SSPF/SSPT ), and block type (SSPB). Material option of Stainless steel (SUS440C or equivalent) is also available. They can be specified to suit various applications.

High Accuracy Torque Transmission

Due to the effective contact angle between the raceway grooves and the balls, the NB BALL SPLINE can transfer large torque. By adjusting preload it is possible to give a higher rigidity and a higher positioning accuracy.



High-Speed Motion and High-Speed Rotation

The outer cylinder is compact and well balanced, resulting in good performance at high speed.
