Some of the surest, time-tested methods of linear actuation are screw drives. Whether lead- or ball- or roller screws, screw actuation remains a large part of the linear actuation equation, thanks to their reliability, accuracy, and relative simplicity of operation. Recently screw drive developments have included advances in materials as well as manufacturing methods leading […]

New tools, services aid ball screw selection and design
Ball screw performance continues to improve, thanks to advancements in manufacturing methods and materials. Newer generations of ball screws have higher load capacities, which means they’re increasingly being used for applications with higher loads as well as more challenging environmental conditions. Hence, the rise in ball-screw-driven actuators replacing traditional fluid power actuation methods in some […]
Ballscrew repair from Dynatect: New calculator to decide when to buy (or refurbish)
Alternatives to the increasing lead time for precision ground ballscrews (PGBS) are driving plant managers to reevaluate procurement options. OEMs often choose to only purchase new precision ground ballscrews (PGBSs) without evaluating repair options. Other choose to maintain no-stock or low-stock of PGBS due to ease of procurement. But now with lead times of 16 to 20 weeks, […]
