Our Rack and Pinion system is a cost-effective way to get the accuracy and performance you need in your CNC application. The system uses a tensioned spring to pull the pinion gear up into the rack teeth. With our system:

The pivot interface 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 pinion drive gear now uses a ball bearing on the timing gear portion where the belt attaches and a dry run sleeve bearing where the pinion rides on the gear rack. The gear rides on a precision ground stainless steel shaft for smooth motion.
A belt tensioning cam 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.

- 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 at least a 380 oz-in NEMA 23 motor or 500 oz-in NEMA 34 Motor for better machine performance.
The drives mate with our drilled and counterbored gear rack which is available in several sizes. These gear racks are 3/4in thick by 1.25in wide (2.5 times the size of normal gear racks!) and feature drilled mating holes every 4 inches. This configuration gives you much greater stiffness, which leads to longer gear life.
This drive is the same drive we use in our Saturn 3 machines. The mounting hole pattern is (2) 3/8-16 tapped holes spaced 6in apart. If you need these to fit onto your machine, give us a call and we can work with you to make sure they are the perfect fit.
