Haydon's newest product line of leadscrew assemblies offers a wide selection of leadscrews made from 303 stainless steel, with Haydon's very own precision rolling process and a tight lead accuracy. They range in diameter from .1875 to .375 inches, and are available with Haydon's Black Ice™ coating, that prevents common flaking problems with other PTFE coatings. The new nuts eliminate typical backlash between the leadscrew and nut interface, making them ideal for precise positioning applications. The nuts are made from Haydon's own self-lubricating polyacetal. Coupled with the screws, there is low drag torque and smooth operation. All the nuts need is Haydon's standard lubricant to work for the life of the application without relubrication, and with Haydon's Black Ice™-coated screws, no lubrication is needed. There are three anti-backlash styles and a new, low-profile freewheeling design. The new nuts are available in a number of diameters and leads, come with a thread mount and can be customized with a variety of standard or special flange configurations.
