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

Types of THK Linear Bearings and Linear Motion Products 

THK linear bearings come in a diverse range, each designed to meet the unique needs of various industries and applications:

Ball Bushings

Perfect for applications requiring smooth and precise linear motion. THK ball bushings offer low friction and high rigidity, ensuring optimal performance and reliability. Moreover, these bushings offer reduced installation times and costs, and an energy saving operation.

THK Linear Guide Rails

THK linear guide rails are the epitome of precision engineering, designed to facilitate smooth and precise linear motion in various industrial applications. Crafted with meticulous attention to detail and advanced manufacturing techniques, THK linear guide rails offer unparalleled performance and reliability.

THK linear guides are classified into two categories which are “Caged Ball Type” and “Full Ball Type (without ball cage)”.

The cage ball type includes SSR (radial type) and SHS (4-way equal load type) models.

The full cage type includes SR (radial type) and HSR (4-way equal load type) models.

Linear Carriages/Blocks

Designed for heavy-duty applications, THK linear carriages and blocks provide robust support and stability, delivering superior performance in demanding environments.
