THK Full-Ball LM Guide Radial Type

Balls roll in four rows of raceways precision-ground on an LM rail and an LM block, and end plates incorporated in the LM block allow the balls to circulate. Since a retainer plate holds the balls, they will not fall out even if the LM block is removed from the LM rail. The low height of the LM block makes this model highly rigid, achieving stable, high-precision linear motion.

Compact with Large Load Capacity


Since it is a compactly designed model that has a low cross-sectional height and a ball contact structure that is suited to large loads in the radial direction, this model is optimal for horizontal guide units.

Mounting Accuracy can Easily be Achieved


Since this self-adjusting model is capable of easily absorbing accuracy error in parallelism and level between two rails, it achieves highly accurate and smooth motion.

Low Noise


The end plate installed at each end of the LM block is designed to ensure the smooth and quiet circulation of the balls at the turning areas.

High Durability


Balls do not undergo differential slip even under a preload or excessive biased load. Due to the product’s high wear resistance, it maintains long-term accuracy.

Stainless Steel Type also Available


A special type whose LM block, LM rail, and balls are made of stainless steel is also available.
