| The NB 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. The NB rotary ball spline can be used for both rotational motion and linear motion. It can be used in scalar robots, the vertical shaft of assembly equipment, and tool changers and loaders. |

| The NB's 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.And, Depending on the application requirements, either a fully machine ground spline shaft or a commercial grade spline shaft can be specified. | ||||||||||||

| The NB's ROTARY BALL SPLINE consists of a spline shaft and a nut. The nut has a spline portion and a rotating portion. In additopn, the use of cross roller elements keeps the housing thickness to a minimum, making the ball spline light and easy to install.Moreover, Because of the single-body construction consisting of the rotating portion which is equipped with cross roller elements and the spline portion, the number of parts is reduced and the cumulative installation error is reduced. | ||||||||||||
