Kerk Mini Series Acme Lead Screw Nuts

The Kerk® MINI Series brings Haydon Kerk Motion Solutions quality, precision and value to products that were previously off limits to lead screw technology. To meet a wide range of applications, the MINI Series includes anti-backlash and standard assemblies.

  • Using a patented take-up mechanism, the self-compensating NTB maintains axial stiffness
  • The NTG allows drag torque to be pre-set according to system requirements.
  • The MINI BFW Series is for applications not requiring anti-backlash and wear compensation.

All Mini Series assemblies include 303 stainless steel lead screws, available with Haydon Kerk Motion Solutions proprietary, long-life Kerkote® TFE coating. All the nuts are maintenance free, manufactured with self-lubricating polyacetal, and designed to run smoothly and efficiently on Haydon Kerk Motion Solutions precision rolled acme lead screws. Perfect for demanding applications, the MINI NTB and NTG nuts provide zero backlash with drag torque of less than 1 oz.-in. (some sizes as low as 0.1 oz.-in.)! Kerk Mini Series Leadscrew Assemblies have what it takes for affordable, precision motion control, sized to fit and built to last.
