Inverted roller screw ISR

planetaryhigh rotational speed

• High load capacity, rigid axial and fast rotational speed • Exceptional sealing performance • Compact and light weight • Reduced number of components in the overall customised design Features: • Very small lead down to 2,4 mm • High rotational speed depending on screw nominal diameter: N.d0 max = 160000 • Compactness, low weight with guiding and sealing functions integrated • Available with axial play or backlash elimination The compact inverted roller screws from Ewellix are a unique variety of the planetary roller screws. Their design 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. They offer an excellent combination of high strength, low pitch and high dynamic performance. performance without any compromise.
