We've taken our hugely popular rack and pinion drive and made it even better! All of the important interfaces in the system have gotten an overhaul to make these drives easier to use and more accurate than before, and the Nema 34 version features a new massive 64 tooth timing pulley. Changes and updates include:- Gear drive spindles now feature super oilite bearings with matched precision ground shafting for higher accuracy.
- The new spindles also now feature a 64 tooth pulley, offering higher resolution and incredible low end torque via a 3.2:1 reduction. With two of these drives and our Nema 34 960 oz-in motors, your machine will put out over 600 pounds of force at low speeds.
- We've replaced the plain bronze bushings at the pivot with a larger 3/4" diameter needle roller bearing and matched ground shaft to eliminate backlash and provide precision alignment with the gear rack.
- We've replaced the older Nema 34 tensioning options with our new PRO tension system, which moves the tension spring further out on our carriages for easier access and greater control.
Package includes:
- Rack and Pinion drive plate
- Needle roller bearing pivot and precision ground shaft
- 1/2" bore Motor pulley
- Super Oilite bearing drive spindle, with 20 tooth gear and 60 tooth timing pulley and matched precision ground shaft
