THK SR Series, SR20-1240L(GK), Linear Guide Rail 20mm width 1240mm Length

The THK Radial Type LM Guide Model features balls roll in four rows of raceways precision ground on an LM rail and an LM block, and endplates incorporated in the LM block allow the balls to circulate. Since a retainer plate holds the balls, they will not fall off even if the LM block is removed from the LM rail. The low height of the LM block makes it highly rigid, achieving stable, high precision linear motion.
