When your design requires precision linear motion – whether it’s retrofit into an existing system or designed into a new one – profile rail linear guides and carriage assemblies are an optimal choice.
Continuing the decades-long tradition of high-quality, innovative and precise linear motion products, Thomson profile rail linear guides are available in a variety of sizes and styles with features that can be matched to your exact application requirements.
When your design requirements call for something outside of the standard Thomson offering, it’s no problem. Our experienced support team can work with you to create the optimal solution for your application.
Thomson provides extensive online resources to help you no matter where you may be in the profile rail purchase decision process:
Performance differences between square rails and round rails are demonstrated, and how these differences impact performance in various applications are discussed. Covered in this video are topics of deflection and alignment and how design application limits help determine the best type of rail for the application.
All linear guides and bearings require application of lubrication. Take a cloth with solvent and remove any old contaminates and lubrication that maybe in place. Once that is done, you can inject the grease fitting directly into the carriage or take a lubricant and apply it directly to the shaft.
Learn the features and benefits of 400 Series profile rails and get an overview of technical specifications.
What is the difference between round rail and square rail? How do you know which one is more appropriate for a given application? How do you size them? Learn the basics of linear guide technology and how to size them for your next application.
This article compares the three most commonly used profile architectures and explores the performance trade-offs that must be considered in finding the optimal configuration for your application.
How to choose between the main types of linear technologies, and how to design automation systems that deliver optimal performance using design requirements, rather than cost, as the primary consideration in selecting linear components.
Advancements in load capacity, life and ease of manufacture allowed an ever-widening range of applications to benefit from nearly friction free linear guidance. Since the introduction of the square, or profile rail, linear guide in the 1970s, the design engineer has been faced with the pivotal question: round or square?
