Gear Couplings?

The FAST’S design, with its lifetime all-metal end ring ,provides up to 300% greater lubricant capacity. This meansthat longer periods between relubrication may be scheduled.

vs. O-ring StyleWhy Is The Design Unique? FAST’S Gear Coupling Size 1 1/2 - 7What Tooth Form Is Used?

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 shut- down 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.It is the only coupling designed to use oil lubrication. To be sure that your couplings provide Maximum Life, alwaysspecify FAST’S The Straight-Faced involute hub tooth form featured in theFAST’S
® coupling is virtually unique in the industry today. It isthis 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.
