Roller Screw Technology
Linear Motion is produced by the action of a screw turning in a nut
The key to the technology is a set of rollers connecting the nut and screw and transferring force between them with very low friction.
Each roller has a large contact area between nut and screw. This gives very high force ratings and low wear / long travel life.
The Roller Screw has a large contact area between rolling components.
A Ballscrew of comparable size will have a lower force rating than a Roller Screw .
