Bi-Directional Ball Screw Assemblies

(SD Series)


SD Series bi-directional ball screws are the choice when you need to move two ball nuts in opposing directions via one motor screw arrangement.   These assemblies consist of a high quality ground screw with a left and right hand thread mated with two ball nuts.  Accuracy grades of C3 and C5 are available.   Screw ends are not quenched hardened to allow for additional machining to be done on your end for coupling and bearing arrangements.   The product ships as one assembly (i.e., with two ball nuts installed on the screw).  The products in the table are typically readily available in small quantities.
