Wide type, for maximum moment loads. The HIWIN linear guideways of the WE series with four ball tracks are designed for high loads and rigidities. The wide profile rail used in the WE series ensures maximum moment load carrying capacity, particularly in the MX direction. The models of the QW series with SynchMotion™ technology offer all the advantages of the standard WE series. Controlled movement of the balls at a defined distance also results in improved synchronous performance, higher reliable travel speeds, extended lubrication intervals and less running noise.
