Series H Gear Couplings
The Series H Advantages:
Larger Bore Capabilities allow the most economical sizeselection for shafts up to 10 5/8". Higher 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. Higher Torque Ratings due to larger tooth pitch diametersthan other
couplings. Versatility in that Series H’s are interchangeable by halfcoupling with competitive
coupling designs. 1 1/2° Curved-Face Teeth are a prime feature of the SeriesH
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.
Crowned Tooth Sizes 1 - 7 Center Flange Bolting:
All
couplings feature precision-drilled flange bolt holes, and
tight tolerance Grade 5 flange bolts to assure a long-lasting
flange to flange and fastener fit. Exposed bolt flanges are
standard. Shrouded bolt flanges can be supplied through size
5. Size #5 1/2 and larger
couplings are only available with
exposed bolt flanges.
Lubrication:
Each sleeve flange is supplied with two pipe plugs 180° apart.
This permits assembly of a full flex
coupling with four lubeplugs positioned every 90°, facilitating lubrication.
The lube seal is a Buna-N O-ring to help retain grease andexclude contaminants. KHP or KSG
coupling greases are
recommended in order to obtain maximum operating life.
Coupling Greases
KOP-FLEX offers greases specifically designed for use in couplingapplications. For proper lubrication and long service life, use KSGStandard Coupling Grease, or KHP High Performance CouplingGrease. See pages 204-206 for detailed specifications. 160
