Kop-Flex Industrial Coupling Product Catalog - Form 8887E

Series H Gear Couplings
Full Flex Coupling Size 8-30
Series H coupling sizes 8-30 feature an all-metal
end ring which can be easily removed to inspect
the hub and sleeve teeth without removing the hub
from its shaft.
All end rings have gaskets and are bolted to the
sleeves. Non-critical surfaces are as-cast, or asforged.
Sleeves have mating male and female
rabbets at the center and end flange joints to
simplify installation. The sleeves have two lube
plugs in the body.
Standardized center flanges allow flex-half
substitution regardless of design or vintage. All
bolts are special with respect to body length, thread
length, and bolt body tolerance.
Sizes 8 - 30 are available with exposed bolts
only.
