FAST'S® Gear Couplings

Fasts Gear Couplings



The all-metal end ring, used exclusively in FAST'S® couplings, eliminates the need for any type of perishable lube seal. The end ring not only provides an escape route for lubricant, but it also pilots the sleeve during start-up and shut-down operations. It further eliminates partial tooth disengagement with resulting tooth overloads by providing sleeve teeth. The sleeve teeth are flush against the inside wall of the end ring.

It is the only coupling designed to use oil lubrication. To be sure that your couplings provide Maximum Life, always specify FAST'S couplings, with the all-metal end ring.
