About the Producer - THK: Precision in Motion

THK Co., Ltd. is a Japanese company known for its expertise in linear motion systems and precision machinery components. The company takes its name from Toughness, High-quality, and Know-how.

Judging from its name, it is clear that they strive for applying their knowledge and experience to develop tough and high-quality products. As they state it, “we aim to contribute to the improvement of society and development of industry by focusing on these three principles in our technology development and product manufacturing processes.”

THK has been revolutionizing industries for decades. With a relentless focus on innovation and quality, THK has earned a reputation for excellence in precision engineering and reliability.

History of THK Linear Bearings

THK was founded in 1971 in Tokyo, Japan under the initial name of Toho Seiko Co., Ltd. Then, in 1972, THK became the first company to develop and commercialize a system that combined rolling contact with linear motion. This system is what we know as the Linear Motion Guides or LM Guides.

The first plant to build the linear motion guides was THK’s Kofu which started operations in 1977. From then on, the company continued to grow exponentially.

In the 1980’s the company expanded production within Japan just years after expanding distribution operations in the US and Germany.

They reach new lands with their manufacturing operations in the 1990s, establishing its presence in the US and Europe.

With this growth came more development. They developed the first Caged Ball LM Guides in 1996 to offer higher performance, and more recently they have provided solutions to applications that include:

  • Machine tools
  • Industrial robots
  • Semiconductor manufacturing systems
  • Liquid crystal manufacturing lines
  • Railway carriages
  • Assistive vehicles
  • Medical equipment
  • Skyscrapers and residences
  • Amusement devices

Jure Pleško is co-owner of Tuli, a family business that helps innovative mechanical engineers by supplying them with machine elements to assemble machines and devices. As part of a family tradition, he grew up with machine elements from an early age and also completed his studies in mechanical engineering, earning a Master's degree in Mechanical Engineering. As a 2-year-old child he was also the inspiration for the company name, because at that time he was shouting a lot and hence the name Tuli, which in translation means screaming. Jure is an innovative mechanical engineer himself, which he proved during his student years with the construction of an electric vehicle, which was also awarded by the Slovenian Fund for Human Resources Development and Scholarships.
