In stock
Compatible with products and accessories

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.
