Features Linear guide: All directions are having high rigidity: the use of four-row circular arc groove chrome rail sales, with four rows of steel ball contact angle of 45 degrees, allowing the ball to achieve the desired two-point contact structure chrome rail manufacturers, energy withstand the load from the vertical and horizontal direction; if necessary, but also to enhance the rigidity of a preload linear guide is divided into square rails and round rails types. Circular rail is the earliest chrome rail products wholesale, but less accuracy compared to square rail. However, the vertical movement of the circular rail is ideal for heavy-duty applications. Which specific use of linear guides should be determined according to the actual needs of the application guide. Square rail grinding requirements inherent in the design of a variety of leading to its initial cost is several times round the rail, but with the performance of the linear guide rail manufacturing technology superior to a circular rail. In general, the higher the square rail load capacity, rigidity and precision and longer life.
