Series H and Fast's Gear Couplings
SERIES H Features & Benefits
- Misalignment Capability - Sizes 1-7 compensate for up to ±1 1/2° static angular misalignment per gear mesh.
Minimizing operating misalignment will maximize the life of the coupling. Refer to the Installation and Alignment Instructions for alignment recommendations. - Large Bore Capabilities allow for economical size selection for shafts up to 10 5/8".
- High Torque Ratings due to large tooth pitch diameters.
- Versatility in that Series H’s are interchangeable by half coupling with other coupling designs.
- 1 1/2° Curved-Face Teeth are a prime feature of the Series H coupling, sizes 1-7. The crowned hub teeth are a 20° full-depth involute tooth form with flank, tip, and root curvature. When used with the straight-faced sleeve teeth, these 1 1/2° curved face hubs offer increased shaft misalignment capability.
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.
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.
