G115-B/5 Precision Ball-Screw Stage

Positioning Linear Stage

The G115-B/5 is a high precision ball-screw linear stage with a 115 mm width, designed to withstand demanding industrial conditions across a wide range of sectors. As the most compact model in the range, it is ideal where space is limited. High stiffness and quality components, including a high precision ball-screw, heavy duty recirculating ball bearing guides and a motor fitted with a high resolution multi-turn absolute rotary encoder, set it apart. The ball-screw is protected from debris by the stage sealing system, while precision recirculating linear bearings, combined with careful machining and assembly, deliver excellent geometric performance.

Applications for Linear Stages

Precision linear stages are central to applications demanding high levels of accuracy and repeatability. They are widely used in laser cutting, scanning, digital printing, and electronics assembly and inspection. They also feature in processes such as Automatic Optical Inspection (AOI) and laser micro-machining, where ultra precision and accurate scan motion are required. In medical and scientific equipment, precision linear stages are relied on for accuracy and repeatability across every cycle.
