In the world of machine tools, precision is everything. The quality of every machined part — its dimensional accuracy, surface finish, and repeatability — is directly tied to the performance of the linear motion system guiding each axis of movement. THK has long been a trusted partner for machine tool manufacturers, providing LM Guides, Ball Screws, and linear encoders that deliver the rigidity, smooth motion, and positional accuracy that high-performance machining demands. Whether the application involves high-speed milling, precision grinding, multi-axis turning, or EDM, THK components are engineered to maintain tight tolerances under the cutting forces, thermal loads, and high-cycle demands that machine tool environments impose. THK's products support both the speed required for productive throughput and the precision required for exacting part quality — enabling machine tool builders to design systems that meet the needs of the most demanding manufacturing applications. With a comprehensive lineup of preloaded guides, precision-ground screws, and integrated motion systems, THK gives machine tool engineers the building blocks to achieve best-in-class performance in every axis.

Ball Screw
The Ball Screw is a high-efficiency feed screw with the ball making a rolling motion between the screw axis and the nut. Compared with a conventional sliding screw, this product has drive torque of one-third or less, making it most suitable for saving drive motor power.
Cam Follower
The Cam Follower is a compact bearing with a high-rigidity shaft and a built-in needle bearing. Most suitable as a guide roller for cam mechanisms and linear motion of automated machines and dedicated machines
Cross Roller Ring
With the Cross-Roller Ring, cylindrical rollers are arranged crosswise, with each roller perpendicular to the adjacent roller, in a 90ã‚œV groove, separated from each other by a spacer retainer. This design allows just single bearing to receive loads in all directions including, radial, axial and moment loads. Since the Cross-Roller Ring achieves high rigidity despite the minimum possible dimensions of the inner and outer rings, it is optimal for applications such as joints and swiveling units of industrial robots, swiveling tables of machining centers, rotary units of manipulators, precision rotary tables, medical equipment, measuring instruments and IC manufacturing machines.
Linear Actuators
Actuators simplify the design and construction of systems by combining separate components, including Linear Motion Guides, drive system (ball screw, belt, or rack & pinion), and base frame, into one part.
This simplification results in a very compact design as well as significant cost savings. Actuators are a very easy way to quickly build up multi-axis systems, streamlining design time, and allowing to focus on performance instead of implementation.
Linear Motion Guide
The LM Guide (Linear Motion Guide) is our main product, incorporating a part with a linear rolling motion into practical usage for the first time in the world. It realizes the development of high-precision, high-rigidity, energy-saving, high-speed machines with long service lives.
Lubrication
An assortment of lubrication associated products is available to maintain sufficient lubrication of machines.
Roller Follower
The Roller Follower is a compact and highly rigid bearing system. It contains needle bearings and is used as a guide roller for cam discs and straight motion. Since its outer ring rotates while keeping direct contact with the mating surface, this product is thickwalled and designed to bear an impact load.
Slide Rail
Slide Rail model FBL is a thin, compact, lightweight and ultra-low price slide unit for finite motion. It has two rows of balls placed between an inner rail (made of a steel sheet roll-formed with precision) and an outer rail. The balls are evenly spaced by a cage press-molded with precision, thus eliminating friction between balls and achieving a smooth slide mechanism.
