Haydon Switch & Instrument Inc. announced the release of a new detailed technical catalog for the leadscrew assemblies product line. Haydon’s new line of leadscrew assemblies includes an offering of acme leadscrews, advanced coatings and anti-backlash nuts. According to the company’s press release, these patent-pending designs not only eliminate backlash between the screw and nut, they also maximize system stiffness and minimize lost motion. Haydon offers five different nut styles, ranging from free wheeling non anti-backlash nuts to a user adjustable anti-backlash nut. Leadscrews are available in diameters ranging from 1/8" to 5/8" and leads as fine as 0.012" up to fast leads as high as 1.25". All Haydon leadscrews are rolled from precision ground 303 stainless steel.Lead screws are also available with Haydon’s unique Black Ice coating, a specially developed PTFE coating process, which eliminates the flaking that commonly occurs with other PTFE coatings used in today’s marketplace. Haydon’s anti-backlash nuts are made from a self lubricating polyacetal thermo plastic. Haydon’s high strength freewheeling nut is made from a glass fiber reinforced polyester that offers high load carrying capability and very high mechanical strength. In addition to the standard nuts custom designed nuts and flanges are available.
