DFU Series Double Flanged Ball Nuts

Double-nut flanged ball nuts for higher rigidity and adjusted preload.

DFU Series Double Flanged Ball Nuts — DFU1604-4 – DFU10020-4 manufactured by YZXQDFU1604-4 – DFU10020-4

Overview

DFU nuts place two ball nut bodies in one flanged housing so preload can be set between them, raising axial rigidity compared with a single nut. Sizes follow the same diameter and lead code as the SFU range.

Key Features

  • Double nut preload
  • Round flange mounting
  • Screw diameters from 16 mm to 100 mm
  • Higher axial rigidity
