G225-IL High Precision Linear Stage

Positioning Linear Stage

The G225-IL is a high precision linear stage engineered to perform in demanding industrial conditions across a wide range of sectors. Exceptional stiffness and high quality components, including ironless linear motors, heavy duty recirculating ball bearing guides and precision absolute linear encoders, give the series a clear performance advantage. G225-IL stages are optimised with high precision, non-contact absolute linear encoders, protected from debris by the stage sealing system. Precision recirculating linear bearings, combined with careful machining and assembly, deliver excellent geometric performance. The result is a stage offering precision, durability and reliability for industrial applications.

Ironless Linear Motor

The G225-IL series takes full advantage of ironless linear motor technology. The absence of a ferromagnetic core in the stator eliminates cogging and any interaction between the stator and rotor magnetic fields, producing exceptionally smooth and precise motion. This makes the series well suited to applications where high accuracy and precision are essential. Its compact design and high power density also suit installations where space is limited, from semiconductor manufacturing equipment to medical devices and robotics.

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.
