The Kerk NTB Series anti-backlash assembly is designed for higher load applications than the ZBX or KHD series units. Using Kerk's patented take up mechanism, it maintains axial stiffness throughout its life while system 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 assembly.

The nut is manufactured with a self-lubricating polyacetal designed to run efficiently on Kerk's precision rolled shafting. Screws are 303 stainless and are available with Kerk’s 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.
