THK manufactures the widest range of linear motion products, including LM guides, ball screws, mechanical actuators, ball splines and more. THK’s creative ideas and unique technology made the company a worldwide pioneer in the development of the Linear Motion (LM) Guide mechanism. Today, its LM Guide devices are an indispensable component utilized in high-performance applications in industrial robots, fiber optics and photonics, vision systems, machine tools, assembly, semiconductor equipment, medical component laser machining, electronic manufacturing, and other industrial automation applications
LM GUIDE
A Linear Guide, or Linear rail, is a system which helps with the movement and supporting of the load of a piece of equipment in a linear fashion, either vertically or horizontally. We have high load, high precision, Caged ball and Non Caged assemblies in stock. Miniature versions of this system are also stocked in hardened stainless steel.
- Four way equal load in all directions
- Automatic self adjusting
- Low centre of gravity and torsional rigidity
- High precision and high speed
- Miniature ranges down to 2.5mm high
- High load capacity
- Compact and low circular guides
