Standard Ball Spline

The 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. 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.

Wide Variety of Configurations

16 shaft sizes with diameters from 4mm to 100mm are available. Seven different types of nuts are available: cylindrical types (SSP/SSPM), flange types (SSPF/SSPT), and block types (SPA/SPA-W/SSPB). Material option of Stainless steel(440C or equivalent) is also available. They can be specified to suit various applications.

Transmission of Torque

NB ball splines can sustain loads in several directions simultaneously . They can be used as a single shaft system and can transmit (or resist) torque.

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.

High-Speed Motion and High-Speed Rotation

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