Fast’s ® Gear Couplings
Why Specify Fast’s ® Gear Couplings?
The Fast’s ® design, with its lifetime all-metal end ring,
provides up to 300% greater lubricant capacity. This means
that longer periods between relubrication may be scheduled.

Why Is The Design Unique?
The all-metal end ring, used exclusively in Fast’s ® couplings,
eliminates the need for any type of perishable lube seal (o-rings,
lip seals, cork gaskets, etc.). The end ring not only provides the
dam over which lubricant must flow to escape, but it additionally
pilots the sleeve with respect to the hub during start-up and shutdown
operations. It further eliminates partial tooth disengagement
with resulting tooth overloads by providing sleeve teeth which
are flush against the inside wall of the end ring.

What Tooth Form Is Used?
The Straight-Faced involute hub tooth form featured in the
Fast’s ® coupling is virtually unique in the industry today. It is
this tooth form that distributes tooth contact pressures across
the full length of the hub tooth, best developing the needed
hydrodynamic lube film, minimizing tooth wear and extending
coupling life. It is the only hub tooth form available in the
standard Fast’s ® coupling line.
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!
