Lead Screw – TFE coated
Standard lead screw nuts are manufactured from self-lubricating plastics. We also offer soft TFE and hard BFE low friction coatings for the lead screw; lubrication to the screw/nut interface occurs by the nut picking up TFE particles from the coating as well as from migration of the internal lubricant from within the plastic nut.
We also supply lead screws with specialist nickel/TFE coatings and offer a choice of coatings used in medium vacuum applications (up to 10-5). Alternatively a BFE coating can be provided. This is a special proprietary hard coating which shares many of the benefits of TFE coating but offers exceptional durability in more aggressive environments and where reduced friction and a permanent coating is desired.
