MISUMI

MISUMI

A ball spline with stepped male threads on both ends. This standard enables highly accurate linear motion and rotational torque transmission. In addition, the contact area between the ball groove machined into the shaft and the steel ball is large, resulting in a large load capacity and long life. Even a single axis can be used as a linear motion guide, allowing for a compact design.
A dustproof seal is attached to the nut, so the ball will not fall off even if the spline shaft is removed.
