The Isotech Rotary Ball Spline is a linear motion mechanism utilizing the recirculating motion of ball elements. It can be used in a wide variety of applications including robotics and transport type equipment.

The standard 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.

Isotech Rotary Ball Splines can be used for both rotational and linear motion. It can be used in SCARA robots, the vertical shaft of assembly equipment, and tool changers and loaders.
