Long-lasting, whether lubricated or not
These new antibacklash nuts last long with little maintenance. They use Haydon's self-lubricating polyacetal and rolled 303 stainless screw material to offer low drag torque and smooth operation for the life of the assembly, all on a single lubrication. They can even run dry with Haydon screws covered with the company's Black Iceô PTFE coating process, which eliminates the usual flaking problems with other PTFE coatings. Haydon developed its own patent pending method for preloading the threaded-nut halves, maximizing system stiffness and reducing drag torque. Its design compensates for wear and eliminates lockup problems when traveling from worn to unworn areas of the screw. They can work with Haydon's current line of linear actuators or by themselves with Haydon's selection of lead screws.
