Rollvis Satellite Roller Screws are precision machine elements for converting rotary movements to linear movements and vice versa. Rollers are interposed between the screws and nut threads as rolling elements.

Due to the high number of contact points, these lead screws can accept very heavy loads. Together with the different type of nuts, Rollvis can therefore supply satellite roller screws for all applications in which rotational speed, forces and shock loads occur alone or in combination.
