A linear guideway facilitates linear movement using ball bearings.
Thanks to the use of ball bearings between the rail and the block, it is possible for a linear guideway to achieve extremely precise linear movement.
In comparison with a conventional guide rail, the friction coefficient is still only one fiftieth.
Due to the restricted guidance of the block on the rail, linear guideways can carry loads in both a vertical and horizontal direction.
* Hiwin has 3 types with ball bearings.
EG, HG, and the miniature type MG
* Hiwin has also a linear guideway with roller
bearings: Type RG
