NB Ball Spline

NB Ball Spline

The NB Ball Spline is a linear motion mechanism that uses the rotational motion of ball elements, which can sustain loads and simultaneously transfer torque. It can be used in various applications, including robotics and transport-type equipment.

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.

NB Ball Spline Feaures: 

High Load Capacity and Long Travel Life

The raceway grooves are machined to a radius close to 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 nuts are available: cylindrical types (SSP/SSPM), flange types (SSPF/SSPT ), and block types (SSPB). The 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.

TYPES OF SPLINE NUT

A wide variety of spline nut designs are available and all spline nuts come with side-seals as a standard feature.
