Yes, you can optimize performance, balance installed costs and extend machine life.
All it takes is the right round or profile rail guide. And expert guidance from Thomson.

We know how to weigh the impact of every variable of your application and lead you to the linear guide that helps you build a better machine, faster. It all starts with the right questions and answers. So, be sure to visit the FAQs page. And test your knowledge with the pop quiz below. Even if you don’t fare well, don’t worry. Our applications engineers have you covered.
