The 5 Start Acme Nut assembly from CNC Router Parts features a new compact design with threads running through the entire nut, providing high load capacity and miles of backlash-free linear travel, along with a rugged aluminum housing, securing the drive nut to your moving axis at a convenient right angle.

These nuts are backwards compatible with our older Acme nuts, and are a drop-in replacement.

When used with our Standard Linear Motion system, this assembly will line up perfectly with our NEMA 23 or NEMA 34 motor mount and bearing blocks.
