Steinmeyer, Inc. has updated UltraThrust ball screw series, with diameters from 32 mm to an enormous 160 mm diameter, pitch ranging from 10 mm to 50 mm, using ball sizes up to 19 mm. This series offers dynamic capacities beyond 1 million newtons.  The new line of large ball screws features a more economic and quieter solution than roller screws. UltraThrust ball screws also offer another significant advantage over roller screws - higher efficiency, typically 90+%. Steinmeyer UltraThrust ball screws are available in several standard as well as custom ball nut configurations complete with precision ground shafts (to 6 meters in length) including finished journals.
