The Series 1510 by Steinmeyer Inc. is equipped with a spring preloaded double nut that compensates for torque variations due to inaccuracies in the ground thread. According to the company’s press release, this results in motion with near-constant idling torque.

The Series 1510 is available in diameters from 3 to 16 mm and features a cylindrical body with attaching thread. The spring preload feature provides the ability to compensate for any wear that occurs over time. Applications for the Series 1510 ball screw include semiconductor machines, inspection equipment, microscope stages, medical scanning devices, miniature robotics and analytical equipment.
