THK Co., Ltd., commonly known as THK, is a Japanese multinational company that specializes in precision mechanical components and systems, with a focus on linear motion technology. The company designs and manufactures products that enable precise, smooth linear motion, including linear guides, ball bushings, ball screws, actuators, vibration isolators, and precision bearings. These components are used across automation, robotics, and machinery applications to improve accuracy, speed, and reliability.

THK was established in Japan in the early 1970s and developed rolling-element linear guides that became widely adopted in industrial equipment. The company expanded its global footprint through international manufacturing and sales networks, establishing facilities and distributors across Asia, Europe, and North America. This globalization supported a broad range of industries and enabled THK to serve customers with localized supply and support.

In addition to core linear motion products, THK offers related systems and solutions, including actuator assemblies, cross-roller guides, and sensing or control components that integrate with automation and robotics platforms. The company emphasizes precision engineering, quality control, and service to support customers in demanding environments such as automotive manufacturing, electronics and semiconductor production, medical devices, and packaging lines.

THK operates as part of a competitive landscape with other suppliers of linear motion and precision bearing components. Its global presence and comprehensive product line position it as a major provider of motion-enabled technology in modern manufacturing and automation.
