VEXpro offers an assortment of gear types, chosen to provide the greatest versatility of gearing options to users. Our sizes were specifically chosen to provide a wide spread of ratio options useful for robot designers. Larger size VEXpro gears are available so designers can accomplish their entire reduction in a single stage where otherwise they would have used more than one!

All VEXpro gears are 20 DP with 14.5 degree pressure angle, and have the same overall width -- this means it is easy to interchange VEXpro gears in your design to change a ratio without modifying the overall system; true versatility.

  • 3/8" hex bores for use on hex shafts
  • Made from 7075-T6 aluminum with a teflon infused ceramic coating or 4140 Steel with a black nitride finish
  • Overall width 0.500"

Note: Hex bore and/or Versakey patterns are not keyed to gear teeth.
