The THK LM Guide is the world's first practical application of rolling linear motion parts. It achieves higher precision, higher rigidity, reduced labor, higher speed, and longer service life of machines.
Features of the LM Guide
Large permissible load and high rigidity
Accuracy averaging effect by absorbing mounting surface error
Ideal four raceway, circular-arm groove, two point contact structure
Superb error-absorbing capability with the DF design
Low friction coefficient
Wide array of options (QZ lubricator, Laminated contact scraper LaCS, etc.)
Caged Ball LM Guide
With the Caged Ball LM Guide, the use of a ball cage allows lines of evenly spaced balls to circulate. This eliminates friction between the balls, resulting in uniform alignment and motion. In addition, grease held in a space between the ball circulation path and the ball cage (grease pocket) is applied on the contact surface between each ball and the ball cage as the ball rotates, forming an oil film on the ball surface. As a result, the oil film is not easily broken.
Full-Ball LM Guide
THK provides series of models suitable for various applications, from miniature to large types for machine tools, and from straight to curved guides.
LM Guide Models for Special Environments
THK created a series of LM Guide models that are suited to use in special environments with high temperature or requiring high corrosion resistance.
Caged Roller LM Guide
The Caged Roller LM Guide is a roller guide that achieves low friction, smooth motion, and long-term maintenance-free operation by using a roller cage. In addition, rollers with optimized lengths and diameters have been utilized as the rolling elements in order to minimize elastic deformation and achieve ultra-high rigidity. Furthermore, the lines of rollers are placed at a contact angle of 45° so that the same rated load is applied in all (radial, reverse-radical, and horizontal) directions.
Full-Roller LM Guide
The roller-type LM Guide is a highly rigid LM Guide because it uses roller as the rolling elements.
LM Guide with Linear Encoder
The global standard Model SHS and THK linear encoder are integrated into one compact unit.
