About THK

THK Co., Ltd. is the Japanese company that invented the linear motion guide: in 1972 it became the first in the world to commercialise rolling-contact linear motion, and its LM Guide remains a standard component inside machine tools, semiconductor equipment and industrial robots. The catalogue built around that invention covers LM Guides, ball screws, ball splines, cross roller rings, electric actuators and complete linear-motion units, giving robot and automation builders precision axes from component to module level. THK also packages its technology as robot-oriented solutions — compact actuators, XY and SCARA-type units and handling modules sold through its Robot Solutions offering — and supplies the transportation equipment sector from separate plants.

Manufacturing is spread across 37 production sites in Japan, the Americas, Europe and Asia, with group sales on the order of JPY 400 billion a year. Because linear guides sit inside almost every articulated robot, gantry and transfer system, THK functions as upstream infrastructure for the wider robotics industry, and it works directly with machine builders on customised motion units. For partners, THK is the reference source for high-precision linear motion components and pre-engineered actuator modules, backed by a global factory and sales network and a five-decade specialisation in rolling-contact motion.

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	9 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	6 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.
