The compact inverted screws from Ewellix are a unique variety of the planetary roller screws. The design of its inverted screws provides a powerful electromechanical drive when compactness and high load capacity are required.
Compact inverted roller screws operate on the same principle as planetary roller screws, whereby the roller run is synchronised with the threaded spindle via gears. Inverted screws offer an excellent combination of high strength, low pitch and high dynamic performance. performance without any compromise.
