THK rolled ball screws are low-priced feed screws that use a screw shaft both rolled with high accuracy and specially surface-ground, instead of a thread-ground shaft used in the precision ball screws.
The ball raceways of the ball screw nut are all thread-ground, thus achieving a smaller axial clearance and smoother motion than the conventional rolled ball screw.
In addition, a wide array of types are offered as standard in order to allow optimal products to be selected according to the application.
