The ES is designed to facilitate the use of the linear ball bearing. The obtainable stroke depends on the allowed deflection of the shafts with respect to their length, to their diameter and to the considered load, as well as the relative position of the elements composing on it.
It can be used with mobile shafts (according to drawings), or with fixed ones. These elements
are manufactured for shafts with a diameter from 6 to 80 mm.
The ball-bearing supports and shaft supports are made of grey cast iron, ground on all sides.
The distance between the shafts is constant within 5 μ m. The parallelism between the fixing bases and the shafts is guaranteed to 10 μ m, according to the quality of the chosen shafts and ball bearings.
