Self-Reversing machined screws

Self-Reversing machined screws
Traditional lead or acme screws require the driven screw to counter rotate to achieve a bi-directional movement of the nut and importantly, to allow the nut to return to its original start position. The self-reversing screw only requires a rotation of the screw in one direction to achieve a reciprocated bi-directional linear movement....

Precision Ball Screws

Precision Ball Screws
The low friction within ball screw designs means that a high mechanical efficiency is delivered compared to that of lead screw designs. A typical ball screw may be 90 percent efficient, versus 30 percent efficiency of a lead screw of equal size. Ball screw specification is often ...
