Teflon Coating
If customer's applications require greaseless screw and nut combination, we offer teflon coated lead screw of stepper linear actuator.
Teflon coated lead screw stepper linear actuator enables it's longer life cycle and better thrust force generation against conventional SUS lead screw.
Teflon coating can be applied in the whole range of lead screw options and all types of PM linear actuators such as External, Non-Captive and Kaptive.
