Amerigear O-Ring Seal Gear Couplings Ameridrives Amerigear ORing Seal Gear Couplings were designed in the early 1950s when the Amerigear Fully Crowned Gear Tooth was patented. In contrast with ordinary gear tooth forms, all three working portions of the tooth are crowned. The teeth are capable of sliding freely in the axial direction without digging or gouging the internal mating teeth. This design offers operational benefits of maximum load-carrying capacity with minimum size, maximum reliability and long life.
