Several years ago in this column I questioned whether linear guideways had become a commodity, noting key engineering differences between various designs and their effect on performance and ...

Lead screws are one of the most common linear-motion devices, thanks to their low cost and reliability (see "A Short History on Ball Screws"). And recent advances in modern machining can make them ...

Ball screws convert rotary motion into smooth, accurate, and reversible linear motion and can often serve as the most efficient and cost-effective choice for linear drive systems. These anti-friction ...

Ball screw models of PHD’s electric actuators are designed for high performance, where as the lead screw design provides lower tier performance at a significant cost savings. Precision ball screw or ...
