Thomson® A&D

Licensed brand of Linear Motion LLC

A legendary name in the Aerospace industry

Thomson® Aerospace & Defense*, a licensed brand of Linear Motion LLC, is a legendary name within the US and global aerospace industry.

As early as 1936, the company, at the time a division of General Motors headquartered in Saginaw, Michigan, was pioneering the field of ball screws for use in automotive power steering systems.

At the beginning of the 1940s the Company reached a new historic milestone by successfully developing the first ball screw used for the legendary B-29 "Superfortress" bomber, the aircraft used at the end of the Second World War which helped to change the global geopolitical balance.
