MATICE NTB
NTB SERIES ANTI-BACKLASH NUTS - Full Range, Flexible Designs
The NTB Series anti-backlash acme lead screw assembly is designed for higher load applications than the ZBX or KHD series units. Using the patented take up mechanism, it maintains axial stiffness throughout its life while system drag torque is held to a minimum. The need to highly pre-load the nut to compensate for load has been eliminated with the Kerk NTB Series nut assembly.
The nut is manufactured with a self-lubricating polyacetal designed to run efficiently on the precision rolled acme lead screw. Kerkite® Composite Polymers are also available as standard options. Screws are 303 stainless and are available with our proprietary, long-life Kerkote® TFE coating. The NTB's simple, compact design can be easily modified for custom applications.
The NTB assembly provides low drag torque, high system stiffness, smooth operation, and long life throughout its load and speed range.
