THK NS-A Ball Screw/Spline

THK NS-A is a precision ball screw/spline that combines ball screw and ball spline grooves on one shaft. This allows the unit to perform rotary, linear and spiral motion. It is designed for equipment that requires accurate positioning and combined rotary and linear movement.

The NS-A has a large lead and preload for smooth, accurate motion. Its rotary nut supports rotary movement, while the integrated ball spline provides linear guidance and torque transmission. The compact structure also helps reduce installation space.

The THK NS-A is available with screw shaft diameters from 8 to 40 mm. The series has a DN value of 70,000 and is available in several size and lead combinations.
