EADmotors Duraplus actuator is a precision engineered device based on a high performance 1.8° stepping motor with an integrated rotating nut. The nut is fabricated from a wide range of optional engineered polymers or SAE 660 bearing bronze to suit the application requirement. The standard polymer used for the catalog offering is Delrin AF. The actuating screw is made of precision rolled stainless steel designed to minimize tolerances in positioning applications. When combined with the polymer nut, the DuraPlus system provides longer life and smoother, quieter operation than conventional designs. Leadscrew lubrication is not required for polymer nuts; however, it is recommended for maximum life.
