They may be single-acting (with a spring return) or double-act<br \/>\n<strong>Ball Screws<br \/>\n<\/strong>Ball screws convert rotary motion to linear motion, or torque to thrust, and vice versa. They are primarily a power screw with a train of ball bearings riding between the screw and the nut in a recirculating track.<strong>Ball Slides <\/strong><br \/>\n\t\t\tBall slides are simple linear motion devices that provide smooth linear motion, accurately controlled by the rotation of<br \/>\n<strong>Ball Splines<br \/>\n<\/strong>Ball splines provide nearly friction-free linear motion while simultaneously transmitting torsional loads. The path of the bearing balls is straight, not helical, which allows for a very efficient coupling device suitable for a variety of applications.
