The ballspline

The ball spline is a linear motion mechanism utilizing the rotational motion of ball elements. It can be used in a wide variety of applications including robotics and transport type equipment

Structure and advantage:

The 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 surface results in high load capacity and long travel life.

Wide Variety of Configurations:

A total of 16 shafts with diameters ranging from 4mm to 100mm are available. Seven different types of nuts to 100mm are available. Seven different types of nuts are available:
- cylindrical types (SSP/SSPM),
- flange types (SSPF/SSPT),
- block types (SPA/SPAW/SSPB)
- Rotary ball-spline (SPR)
