Linear Motion. Optimized.

John B. Thomson Sr. invented the Ball Bushing® bearing and, in essence, anti-friction linear technology, over 75 years ago, and his company has continued to pioneer linear motion innovation ever since. Over the years, the Thomson product range has grown significantly to address the needs of motion designers.

Today, the Thomson brand is globally recognized and trusted as a leading producer of high-quality motion control technology, on-time delivery, controlled costs and reduced risk. Most, if not all, of the credit to the company’s success can be attributed to a long history of dedicated, persevering employees that work together toward a common goal of fulfilling the Thomson brand promise.
