A structure with a wide rail and low center of gravity. It is thinner than HSR and is advantageous when Mc moment stiffness is required.
[Features]
· LM rails and LM blocks feature 4 precision-ground raceways that the balls travel along. The end plates embedded in the LM block circulate the rows of balls.
· Compact heavy load: A high number of effective balls makes it possible to obtain high rigidity in all directions. Has a wide rail width and can adequately withstand moments with a single shaft.
There is a high rigidity in the horizontal direction and there is no need of reinforcement such as horizontal pressing due to large secondary moments being incurred on the rail cross-section.
· The self-aligning capability: The self-adjusting power effect of the front-facing combination (DF set) of unique circular arc groove allows to absorb mounting errors even if preload is applied, resulting in highly accurate, smooth linear motion.
