Long lead ball screws

The Ewellix range of large high pitch ball screws has been specially developed by Ewellix for fast linear speeds to increase productivity and represent a winning combination of precision roller technology and end cap return. This design is suitable for most positioning applications thanks to the precision ground outer surface of the nut and flange support. The products in this series are designed by Ewellix to provide even greater positioning accuracy, as well as slip prevention. Additionally, Ewellix also offers various types of threaded nuts to minimise the mass inertia torque for high pitch spindles. The spindle is rigidly fixed to the machine frame, while the ball screw nut rotating in a bearing housing is driven by a traction belt and moves along the spindle. Ewellix also offers a range of rotating nut solutions to minimize the inertia phenomenon associated with long rotating shafts. The long lead screw shaft is rigidly fixed to the machine frame while the ball nut, rotating inside a bearing housing and driven via a tension belt, moves along the screw shaft.
