7075 T6 Aluminum and 4140 Steel pinions reduce weight and rotational inertia of your gearbox. The VEXpro teflon infused ceramic coating greatly reduces the friction of your gearbox at the initial motor reduction (where drag has the most effect on the system).

20 DP Pinions will allow you to create the same exact reduction you’ve been creating with the VEXpro 32 DP gears but in a smaller, more compact space.

VEXpro offers 20 DP gears specifically sized for some of the most popular motors in FRC, including the Falcon 500, CIM, BAG, RS550 and RS775.

  • 14.5 degree pressure angle
  • Mounts to various sized FRC motors
  • Mounts to other motors or gearboxes using a similar shaft

Note: Tight Fit Falcon Pinions are slightly out of tolerance, resulting in a tight fit on the Falcon Shaft. They have been re-kitted into 6-packs, and are sold at a discount. Tight Press Falcon Pinions may require some shaft sanding to become a slip fit.

This image shows the amount of space that can be saved by using 20 DP gears over 32 DP gears. These assembly on the left is using an 6T and 50T gear, while the assembly on the right is using a 12T and 100T. This equates to the same gear reduction, in a fraction of the space!
