They are units designed to transform a rotary motion into a linear one by means of a recirculating ball screw, which transmits the motion, and one or more recirculating ball guides to support and guide the load.

All units are designed to give maximum protection to internal components. They can both be used in environments with contaminants and in clean room, where the release of polluting particles is not allowed.

The units are designed to have a high efficiency, the guide sliders have tanks for lubrication which increases their duration and reduces downtime for maintenance.
