Key Features & Benefits
Duff-Norton has been manufacturing Acme screws and nuts for actuator products for decades and is now applying those years of experience to bring you an expanded assortment of Acme screws and nuts for your application requirements.
Centralizing class screw and nut assemblies – Excellent lead accuracy. Centralizing Acme Screws have limited clearance at the major diameter of screw and nut
and are used extensively for feed screws. The limited clearance enables a
bearing at the major diameter to maintain alignment of the thread axis
preventing wedging on the flanks and part sagging.
