Our Standard Rack and Pinion Drive system is perfect for larger format machines, 4' x 8', 5' x 5', and larger.
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.
The system provides a 3:1 belt reduction (2.73:1 with 22 tooth pulley), putting NEMA 23 stepper motors in an optimal range for speed and power. 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 Rack Clamps
and combine lengths of rack to get the travel you desire.
