Mill Ball Screw XYZ-Axes Retrofit Kit
The Mill Ball Screw XYZ‑Axes Retrofit Kit is a retrofit upgrade for Sherline milling machines that replaces the standard X and Y axis lead screws with precision ball screws to reduce backlash and improve smooth, accurate motion. It includes rolled ball leadscrews with BSH nuts (10 mm × 2 mm lead, C7 accuracy), high-torque stepper-motor couplings and mounts, and ball screw mill saddles assembled at the factory for easy installation. Why it matters:
  • Better positional accuracy and smoother CNC motion on the X and Y axes
  • Fully assembled components ready to install
  • Works with high-torque stepper motors for improved performance
  4 week lead time When ordering your new Ball Screw Retrofit Kit, you will need to supply the following information for your current machine so we can ensure you receive the correct length of the ball screw for each axis:

Mill Ball Screw Z-Axis Retrofit Kit

The Mill Ball Screw Z‑Axis Retrofit Kit is an upgrade kit for Sherline milling machines that replaces the standard Z-axis leadscrew with a precision ball screw assembly to reduce backlash and improve smoothness and positional accuracy. It includes a rolled ball screw with BSH nut, stepper-motor coupling and mount, and modified saddle components, and is ready to install with all key parts assembled at the factory.

Why it matters:
• Stronger, smoother Z-axis motion and better CNC performance
• Tight tolerances for increased precision
• Some loss of max travel due to the new saddle design
