A Linear Guideway allows a type of linear motion that utilizes rolling elements such as balls or rollers. By using re- circulating rolling elements between the rail and the block, a Linear Guideway can achieve high precision linear motion. Compared to a traditional slide, the coefficient of friction for a Linear Guideways is only 1/50th. Because of the restraint effect between the rails and the blocks, Linear Guideways can take up loads in both the up/down and the left/right directions. With these features, Linear Guideways can greatly enhance moving accuracy, especially, when accompanied with precision Ball Screws.
