Our Standard Rack and Pinion Drive system is perfect for larger format machines, 4' x 8', 5' x 5', and larger. This NEMA 34 R&P Drive system features 4 times the torque capacity of our NEMA 23 R&P Drive system by using larger series belts and pulleys.
They are designed to mount directly to one of our Extended Linear Carriages riding on a horizontal cold rolled steel rail (must overhang 1530 or 3030 extrusion by 1/2"), and interface with our Gear Rack that can be mounted using our Rack Clamps.
Multiple lengths of gear rack can be combined to achieve longer travel lengths. Extended linear carriage, gear rack, and rack clamps are sold separately.
The included EZ-tension kit allows for simple adjustment of the mesh force into the rack. It integrates seamlessly with our extended linear carriages and is still compatible with our rack clamps for easy machine setup.
Due to the higher torques of NEMA 34 motors, this system features a 2:1 reduction instead of the 3:1 reduction on our NEMA 23 system for higher speeds. If you prefer a lower reduction for more power and less speed, this is available in our NEMA 34 PRO R&P drives
. The videos below show the system in action.
Our R&P drives interface with 20 pitch, 20 degree pressure angle Gear Rack
, which we offer in convenient spliceable sections:
Simply mount rack to the extrusion underneath the rail using our innovative rack clamps
and combine lengths of rack to get the travel you desire.
