*Structure and Features Balls roll four rows of raceways precision-ground on a rail and a block, and endplates incorporated in the carriage allow the balls to circulate. Since retainer plates hold the balls, they do not fall off even if the rail is pulled out. This model is an integral type of linear guideway that squares an internal structure similar to other model, which has a proven track record and is highly reliable, with another and uses two rails in combination. It is machined with high precision. The two rails are also machined with high precision in relative straightness. As a result, extremely high accuracy in orthogonality is achieved. Since an orthogonal linear guideway system can be achieved with model MSH alone, a conventionally required saddle is no longer necessary, the structure for X-Y motion can be simplified and the whole system can be downsized.*Four-Way Equal Load The four trains of balls are allocated to a circular contact angle at 45°,thus each train of balls can take up an equal rated load in all four directions. Moreover, a sufficient preload can be achieved to increase rigidity, and this makes it suitable for any kind of installation.*High Rigidity Since balls are arranged in four rows in a well-balanced manner, this model is stiff against a moment, and smooth straight motion is ensured even a preload is applied to increase the rigidity. The rigidity of the blocks is 50% higher than that of a combination of two carriages secured together back-to-back with bolts. Thus, MSH is an optimal linear guideway for building an X-Y table that requires high rigidity.Applications Swiss-type lathe and Biaxial operation of the machine.
