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.Where can you get started?
Thomson provides extensive online resources to help you no matter where you may be in the profile rail purchase decision process:
Proper installation and alignment are critical for profile rail linear guides to function. Watch this video to learn about Thomson's four categories of mounting tolerances for profile rail and how they can help you avoid misalignment.
With three families of profile rail (each available in two configurations), Thomson has optimized its portfolio to simplify the sizing and selection process for you. Watch this video to determine how to align your application's needs with the ideal profile rail solution.
VIDEO: Round vs. Square Rail Technology
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.
VIDEO: Tech Tips – Lubricating Linear Rail
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.
