THK Celebrates 50 Years of Providing Innovate Linear Motion Products

Schaumburg, IL – As the pioneers in linear motion products, THK has introduced innovations in high-quality, precision motion components for the past five decades, setting the benchmark for the industry.

In 1971, THK was established in Meguro-ku, Tokyo, under its first name, Toho Seiko Co., Ltd. In 1972, THK became the first company in the world to develop a method of linear motion with rolling contact and began manufacturing and selling the commercialized result: Linear Motion (LM) Guides. In 1977, THK's Kofu Plant, the first full-scale LM Guide production plant, was established. This was THK's first step in expanding production facilities. From there, THK took operations worldwide and expanded to North America and Germany. As THK set out on growing globally, it did so with a spirit of innovation and the determination to solve customer dilemmas with cutting-edge solutions. The product line expanded to include Ball Splines and Ball Screws, LM Guides, Actuators and Cross-Roller Rings. A commitment to innovation led to the development of THK’s patented Caged Ball design. Consisting of a plastic structure that provides a pocket in which the metal balls roll and stay separated, this design reduces wear and friction, retains lubricant that provides longer service life for the bearings and gives the customer superb noise reduction during operation.

Innovative products, along with knowledgeable sales, engineering and mechatronics departments, have made THK the world leader in linear motion components. In fact, in the last ten years alone, THK has sold enough LM Guides that if lined up would circle the globe at the equator.

Pioneers in linear motion guides since 1971, THK continues that same spirit in 2021. Recently, THK introduced a variety of innovations to meet the needs of customers in an ever-changing world. Their products can be found in robotics, manufacturing machinery, medical/surgical devices, packaging, semi-conductor manufacturing and much more. “We are proud of all we have accomplished over the past 50 years,” commented Ed Johnson, vice president of sales, THK America, Inc. “We are the components that go inside of what you build, and we are pleased that so many of our customers have honored us as a valued partner. We all have the need to move forward and whether you measure that movement in sub-microns or in meters, THK will continue to listen to your needs and provide the solutions to exceed them. The only limitation is your imagination, because if you can think it, we can assist you in designing and building it.”

THK manufactures the widest range of linear motion products, including LM Guides, Ball Screws, Mechanical Actuators and Ball Splines, Cross-Roller Rings and more. All THK products have been designed and manufactured to meet the strictest requirements. THK’s experienced Global Engineering Team can provide customized linear motion solutions from their standard linear motion products as well as from mechatronics products for the most demanding applications.
