Precision Ground High Lead Ball Screw, 20mm Thread Dia, 40mm Lead, 45-1/2" Thread Length is listed under Ball Screws & Lead Screws — rolled and ground ball screws, acme lead screws and nuts. Ball screws and lead screws convert rotary motion into linear motion, or vice-versa, with high precision and efficiency. Ball screws utilize recirculating ball bearings between the screw shaft and the nut, providing low friction, high efficiency (typically >90%), and minimal backlash.
