The Designed for superior load-bearing the hg, And rigidity series linear guideways outperforms comparable products with circular and arc groove designs Optimized structural design. It offers balanced load along with self, And lateral aspects, Ratings in, Reverse radial all radial-aligning features to correct any installation misalignment thus, The Designed for longevity, Hg series linear guideways provide rapid movement and remarkable accuracy smooth linear motion. Linear guideways provides linear motion by re, Circulating rolling elements between a profiled rail and a bearing block. The ratio of friction on a direct guiding rail represents a mere 1 in 50 compared to a traditional slide and these items consist of able to accommodate heavy loads all directions. With these features, A linear guideway can achieve exceptional accuracy and greatly enhanced moving accuracy. Hiwin corporation offers multiple linear guideway series, Each featuring different options loading capabilities, For sizes, Accuracies, And more.
