About Thomson

Thomson Industries, Inc. is a US manufacturer of linear motion control solutions, part of Regal Rexnord Corporation, with its published corporate address in Downers Grove, Illinois and a long-standing manufacturing base in Radford, Virginia. The business grew out of a wartime project to reduce friction in airplane propeller motion, which led to the invention of the ball bushing bearing — Thomson is credited with inventing the linear ball bushing more than 60 years ago and remains a recognised leader in the field. Thomson marked its 75th anniversary in 2021. Its catalogue is among the broadest in mechanical motion: linear ball bushing bearings and RoundRail guides, profile rail guides, ball screws and lead screws (combining the Thomson, Warner, BSA and Neff screw lines, with 70+ years of ball screw R&D), ball splines, linear actuators, gearheads, clutches and brakes, and complete linear systems, supported by LinearMotioneering design tools and online CAD downloads.

Thomson passed through Danaher Motion ownership and a 2018 merger into Altra Industrial Motion before Altra combined with Regal Rexnord in 2023. Its ball screw application history runs from the Boeing B-29 to modern missile seeker gimbal stabilisation, alongside factory automation and medical markets. For robotics builders, Thomson supplies the linear axes — screws, guides and actuators — behind gantries, stages and machine slides.

GlobleMatch Trust Signals

A directory that doesn’t sell stars. Trust Signals are built only from verifiable facts — never from anonymous ratings, and never for sale. There is no single hidden score.

Public information coverage	8 of 9 fields on the standard profile could be filled from public sources. This counts how much public information exists about the company — not how good the company is. The nine fields are listed in the methodology. Claiming the profile lets the company complete the remaining fields itself.
Last verified	9 November 2026 — facts on this profile were checked against the sources listed below. Profiles are re-checked on a published 90-day cycle; this date is never quietly refreshed.

Claim this profile to unlock response record, directory tenure and peer endorsements. The full methodology — what each signal measures and how it is calculated — is published in the Trust Signals methodology, including a change log.
