In addition, the <strong>LM</strong> block can receive a well-balanced preload, increasingthe rigidity in the four directions while maintaining a constant, low friction coefficient. With the lowsectional height and the high rigidity design of the <strong>LM</strong> block, this model achieves highly accurate andstable straight motion.[4-way Equal Load]Each row of balls is placed at a contact angle of 45° so that the rated loads applied to the <strong>LM</strong> blockare uniform in the four directions (radial, reverse radial and lateral directions), enabling the <strong>LM</strong> <strong>Guide</strong>to be used in all orientations and in extensive applications.[Self-adjustment Capability]The self-adjustment capability through front-to-front configuration of <strong>THK</strong>'s unique circular-arcgrooves (DF set) enables a mounting error to be absorbed even under a preload, thus to achievehighly accurate, smooth straight motion.[Global Standard Size]SHS is designed to have dimensions almost the same as that of Full Ball <strong>LM</strong> <strong>Guide</strong> model HSR,which <strong>THK</strong> as a pioneer of the linear motion system has developed and is practically a global standardsize.[Low Center of Gravity, High Rigidity]As a result of downsizing the <strong>LM</strong> rail section, the center of gravity is lowered and the rigidity isincreased.<strong>LM</strong> <strong>Guide</strong><strong>Industrial</strong> <strong>Technologies</strong>A1-113
