Our rack and pinion system just got a major upgrade. We've collected your feedback and made some significant improvements to the drive. As a result, we have a drive with better accuracy than the originals.
 
Some improvements we have made over the original drives:
  • The pivot interface now has 3 bearings instead of a bushing. These bearings plus a lockdown collar system eliminate plate wiggle and keep the pinion riding straight and true on the rack.
  • The universal mounting plate can accept either NEMA 23 or NEMA 34 motors. To convert between size you only need to change the pulley, belt, and drive spindle.
  • The drive spindle has been upgraded to provide smooth motion. The spindle now uses a ball bearing where the belt attaches and a dry run sleeve bearing where the pinion rides on the gear rack. The bearing ride on a precision ground stainless steel shaft for smooth motion.
  • A belt tensioning cam that allows you to adjust the belt tension without disassembling anything. 
  • A high resolution 3:1 belt drive reduction for both NEMA 23 and NEMA 34 motors.
  • Simple spring tension adjustment for gear pre-loading to rack

What's in the package

NEMA 23
  • Universal Rack and Pinion drive plate for NEMA 23 or NEMA 34 motors.
    • The triple bearing pivot assembly with the collar lockdown system is pre-installed (Bolt has 3/8-16 mating thread).
    • Double bearing drive spindle. Features a 20 tooth pinion gear and 60 tooth timing pulley (3mm pitch). Comes pre-installed on the plate with a precision ground stainless steel shaft.
    • The belt tensioning cam is pre-installed on the plate.
  • 20 tooth timing pulley for motors with 1/4” or 3/8” bore to match your motors shaft size.
  • 3mm pitch timing belt.
  • Motor mounting screws and nuts (motor not included).
  • Spring pre-load assembly. Includes 2 mounting brackets, spring with tensioning bolt.
NEMA 34
  • Universal Rack and Pinion drive plate for NEMA 23 or NEMA 34 motors.
    • The triple bearing pivot assembly with the collar lockdown system is pre-installed (Bolt has 3/8-16 mating thread).
    • Double bearing drive spindle. Features a 20 tooth pinion gear and 64 tooth timing pulley (5mm pitch). Comes pre-installed on the plate with a precision ground stainless steel shaft.
    • The belt tensioning cam is pre-installed on the plate.
  • 20 tooth timing pulley for motors with 1/2” bore.
  • 5mm pitch timing belt.
  • Motor mounting screws and nuts (motor not included).
  • Spring pre-load assembly. Includes 2 mounting brackets, spring with tensioning bolt.
 

Product Notes

  • The motor is not included. Use our 420 oz-in NEMA 23 Motors or 960 oz-in NEMA 34 Motors for better machine performance.
  • The drives mate with our drilled and counterbored gear rack which is available in 29", 41", and 54" sections. These gear racks are 2.5 times the size of normal gear racks and feature drilled mating holes every 4 inches, giving your great stiffness, which leads to longer gear life.
  • This drive mounts directly to our Extended Linear Carriages riding on one of our linear rails. It also mounts directly to our Saturn Series machines. If you need getting these to fit onto your machine, give us a call and we can work with you to make sure they are the perfect fit.
