Product Description

Positioning Linear Stage

Introducing the G115-IL, the latest Compact high-precision linear stage from Gorman Dynamics. This linear stage is designed to withstand even the most demanding industrial conditions, making it ideal for use in a variety of industries. Its high stiffness and use of high-quality components, such as high-performance ironless linear motors, heavy-duty recirculating ball bearing guides, and precision absolute linear encoders, set it apart from the competition. The G115-IL series stages are optimized with high-precision, non-contact absolute linear encoders that are protected from debris by the stage sealing system. Precision recirculating linear bearings, along with machining and assembly , enable excellent geometric performance specifications. At Gorman Dynamics, we pride ourselves on delivering high-quality, reliable solutions for our clients. The G115-IL is no exception, offering unparalleled precision, durability, compact, and safety for a wide range of industrial applications. 

 

Ironless Linear Motor

The G115-IL Series is a cutting-edge solution that leverages the advantages of ironless linear motors. One of the key benefits of these motors is their high precision and accuracy, which are critical factors in many industrial applications. The absence of a ferromagnetic core in the stator eliminates cogging and any interaction between the stator and rotor magnetic fields. This produces incredibly smooth and precise motion, making it an ideal solution for applications where high accuracy and precision are essential. The G115-IL Series delivers unparalleled performance, making it a reliable and efficient solution for applications requiring a high degree of accuracy and precision. Additionally, its compact design and high power density make it ideal for use in applications where space is limited. Whether it is for semiconductor manufacturing equipment, medical devices, or robotics, the G115-IL Series delivers the precision and accuracy that these industries demand.

 

Applications for Linear Stages

Precision linear stages play a critical role in various applications that necessitate high levels of accuracy and precision. These stages are frequently utilized in industries such as laser cutting, scanning, digital printing, and electronics assembly and inspection. They are also deployed in processes such as AOI (Automatic Optical Inspection) and laser micro-machining, which demand ultra precision and accurate scan motion. In medical and scientific equipment, precision linear stages are pivotal in ensuring accuracy and repeatability. In any industry or application, utilizing precision linear stages is crucial for achieving desired outcomes and delivering top-quality output.
