Ameridrives Amerigear O'Ring Seal Gear Couplings were designed in the early 1950's 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.

The FAST'S^© Coupling was the standard in the metals industry for decades. Ameridrives now offers the labyrinth/metal ring seal option for your coupling needs. This coupling is a part for part "Drop-In" replacement for the FAST'S^© coupling.

Amerigear Class I High Performance Gear couplings with fully crowned gear teeth are designed for higher torque, higher speed, and higher misalignment to accommodate the increased performance demands of modern, rotating equipment. Standard and custom designs are manufactured to precision tolerances to meet weight, size, temperature, speed and misalignment requirements.
