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.

All are available with leads ranging from 0.5 3 mm and offer a maximum speed of 4500 RPM.
