Motion and precision positioning systems expert PI (Physik Instrumente) released a new catalog of engineered products necessary for precision positioning of medium loads used in industry and research.
The products high-lighted in this catalog are developed to move loads of 10kg to 50kg (22lb to 110lb) over distances up to 300mm. Rotation stages provide rotation angles of 360 degrees. Achieving accuracy in the micron and sub-micron realm is not a trivial matter and stages with ballscrew/servo or stepper drives combinations can be superior to direct drive motors when it is necessary to achieve high holding force, torque or particularly for vertical positioning.
Linear and rotary stages are also available in compact sizes for easy installation into limited space.
