Teflon Coating

If customer's applications require greaseless screw and nut combination, DINGS' offers 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 in DINGS' and all types of linear actuators such as External, Non-Captive, Electric Cylinder and Kaptive.

In addition, anti-backlash nut also can be combined with teflon coated lead screw too.
