CAD Library

Helix Linear Technologies’ CAD Library provides engineers, designers, and automation professionals with free, ready-to-use 3D models and CAD files for our precision linear motion components. Whether you’re working in mechanical design, robotics, factory automation, medical devices, aerospace systems, or semiconductor equipment, our CAD resources streamline your product development process and reduce design time.



Our extensive library includes detailed 3D CAD models, dimensional data, and technical specifications for a wide range of motion components, from lead screws and ball screws to linear actuators, electric cylinders, and precision torque splines. These files are provided in multiple native formats to support seamless integration with popular CAD systems, enabling engineers to validate clearances, fit, and mechanical performance early in the design cycle.



Accessing the right CAD model early in your product workflow can significantly improve accuracy and efficiency. By downloading Helix’s CAD models, you gain access to precise geometry you can insert directly into assemblies, simulate system behavior, and optimize performance before physical prototyping. Our CAD Library is continually updated with new models and expanded support for additional formats to meet evolving engineering needs.



In addition to the downloadable CAD files, our team of application engineers is available to help clarify specifications, suggest alternative components, and support your selection of linear motion products that best fit your design requirements. Leveraging these resources helps design teams reduce development risks, accelerate time to market, and ensure the highest levels of mechanical accuracy.
