The "Retainer" technology developed by THK, the first in the world.
THK, which developed the world's first LM guide, created a LM guide with retainers that dramatically improves the performance of conventional products, achieving long life, high speed, and long-term maintenance-free operation, similar to rolling bearings.

basic information
● A silent structure that minimizes metal contact The interference noise between balls has been eliminated thanks to the ball retainer, resulting in a quiet operation. ● A structure that provides aligned motion to the balls The balls are held by a belt-like ball retainer, allowing them to align uniformly and circulate. There is no meandering motion of the balls, and sudden friction fluctuations are eliminated, resulting in stable movement. ● A unique retainer structure that excels in high-speed performance The ball retainer minimizes heat generation due to mutual friction between the balls, enabling excellent high-speed performance. ● Enables long-term maintenance-free operation The grease retention structure (full circumference grease pockets) features grease pockets around the entire circulation area of the balls, ensuring constant lubrication and allowing for long-term maintenance-free operation.
