Hiwin Corporation is a global manufacturer of Linear Motion Control products including Ballscrews and Linear Guideways. 

Ralph W. Earl Company is a stocking distributor of Hiwin linear guideways and ballscrews, and has the ability to cut linear guideways in-house to meet your specific length requirements.


Linear guideways provides linear motion by re-circulating rolling elements between a profiled rail and a bearing block. The coefficient of friction on a linear guideway is only 1/50 compared to a traditional slide and they are able to take loads in all directions. With these features, a linear guideway can achieve high precision and greatly enhanced moving accuracy. Hiwin Corporation offers multiple linear guideway series, each featuring different options for sizes, loading capabilities, accuracies, and more.
