Индастриал Технолоджис www.industrial‐technologies.com.ua +38 044 498 21 94Features of Each ModelWide Rail Model HRWStructure and FeaturesBalls roll in four rows of raceways precision-ground on an LM rail and an LM block, and endplatesincorporated in the LM block allow the balls to circulate.Since retainer plates hold the balls, they do not fall off even if the LM rail is pulled out. (except modelsHRW 12 and 14LR).Each row of balls is placed at a contact angle of 45° so that the rated loads applied to the LM blockare uniform in the four directions (radial, reverse radial and lateral directions), enabling the LM Guideto be used in all orientations. In addition, the LM block can receive a well-balanced preload, increasingthe rigidity in four directions while maintaining a constant, low friction coefficient. In a low centerof gravity structure with a large rail width and a low overall height, this model can be used in placeswhere space saving is required or high rigidity against a moment is required even in a single axisconfiguration.[Compact, Heavy Load]Since the number of effective balls is large, this model is highly rigid in all directions. It can adequatelyreceive a moment even in a single rail configuration.Additionally, since the second moment of inertia of the rail is large, the rigidity in the lateral directionsis also high. Accordingly, it does not need reinforcement such as a side support.[Self-adjustment Capability]The self-adjustment capability through front-to-front configuration of THK's unique circular-arcgrooves (DF set) enables a mounting error to be absorbed even under a preload, thus to achievehighly accurate, smooth straight motion.LM GuideIndustrial TechnologiesA1-177
