MOTION CONTROL: Steinmeyer Inc. has announced a new product to its extensive line of miniature ball screws. These 5-mm diameter screws are the perfect solution in applications such as micromanipulators, miniature robotics and compact actuators. Available in four nut styles: series 1112 single nut with connecting thread without wipers; series 1412 is a single nut with double flange and wipers on both ends; series 1214 is a cylindrical nut without wipers; and series 2422 is the company’s “quiet line” series, with a single nut that uses end-cap ball returns manufactured from plastic rather than metal tubes, making the screw virtually noiseless. All are available with leads ranging from 0.5 3 mm and offer a maximum speed of 4500 RPM.
