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 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.
External Anti-Backlash Nut
* According to different screw lead code selection, length of Anti-Backlash nut can be changed.
Non-Captive Anti-Backlash Nut
