POWER SCREWS & NUTS

Lead screw and nut combinations are often chosen from standard ranges to convert the rotary motion of the screw into a linear movement. However sometimes the nut design can be adapted to deliver more than one advantage.One big advantage is that nuts can be manufactured in just about ...

Ground Ball Screw accuracy, rolled screw pricing

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 a ...
