Lead screw Teflon coating

Teflon Coating

If your application requires a greaseless screw and nut combination, DINGS’ offers Teflon coated lead screws for stepper linear actuators.

Teflon coated lead screws can improve life cycle and thrust force generation compared with conventional SUS lead screws.

Teflon coating can be applied across the lead screw option range and actuator types including External, Non-Captive, Electric Cylinder, and Kaptive. Anti-backlash nuts can also be combined with Teflon coated lead screws.
