Amerigear® Gear Couplings Metal Labyrinth Seal

The all-metal end ring, used exclusively in FAST'S® couplings, eliminates the need for any consumable oil sealing system. The end ring not only provides an escape route for the lubricant but also guides the sleeve during starting and stopping operations. Furthermore, by ensuring that the sleeve teeth are flush with the inner wall of the end ring, it eliminates partial tooth disengagement and the resulting tooth overloads.

This is the only coupling that can use oil lubrication exclusively. To ensure your couplings provide maximum service life, always make sure you choose FAST'S couplings with the all-metal end ring.
