Using the Kerk patented take-up mechanism, the NTB series antibacklash lead screw assemblies maintains axial stiffness while system torque is held to a minimum, providing smooth operation and long life throughout its load and speed range. The NTB series assembly has eliminated the need to highly preload the nut to compensate for load. The series is fl exible in terms of material; customers can choose the material that best suits their particular application, i.e. temperature, chemical compatibility, speed, and product life. The nut is manufactured with a self-lubricating polyacetal designed to run effi ciently on Haydonkerk’s precision rolled shafting. The screws are 303 stainless and are available with long-life Kerkote TFE coating, which eliminates the need for external lubrication and maintenance. Available with a triangular fl ange, round fl ange or thread mount, the assembly is available in a variety of diameters and lengths.
