1.1 Description
1.1.1 The Airflex WCB water-cooled tensioner is
designed for constant tension applications. It is
exceptionally well suited for high inertia stop-
ping and rapid heat dissipation. The design of
the WCBtensioner permits midshaft or
endshaft mounting. The rugged construction
ensures long, trouble free service. Several
models are available having single and multiple
friction discs. The tensioner model number
identifies the number of discs and the disc
diameter. For example, 114WCBmeansone
14" diameter disc. When size, such as 14WCB,
is referred to in this manual, it means that the
information given applies to all models using
the 14" diameter disc; i.e., 114WCB, 214WCB,
etc.
1.1.2 Standard 8 and 14 WCBmodels have parts list
numbers ending with "B". These units have
riveted friction lining and no stop tubes or wear
rings.
1.1.3 Standard 18, 24 and 36 WCBmodels have
screwed on friction lining, stop tubes and wear
rings. These units have part list numbers
ending with "E".
1.1.4 Some earlier 18, 24 and 36 WCBunits have
riveted friction lining and no stop tubes or
wear rings. These units have part list numbers
ending with "B".
1.1.5 Tensioners can be used for either closed loop or
open loop water systems.
1.1.6 This manual includes metric equivalents
usually shown in (#) following the U.S.
measurement system value. Be sure to use
thecorrect value.
1.2 Specials
1.2.1 WCB models with high coefficient lining are
designated with the following alphanumeric
designators:
1.2.2.1 Models ending with "C" (146XXXC)are
WCB’s with riveted linings and no stop tubes.
8 and 14 WCB’s are current HI-CO elements
and 18,24 & 36 models are discontinued.
1.2.1.2 Models ending with "D" (146XXXD) are
WCB’s with screwed on linings and stop tubes.
18, 24 & 36 modelsarecurrent HI-CO
elements.
1.2.2 214WCBModels with an "A" (146XXXA)
designator are elements with a machined
cylinder face to accept a mounting flange to
accept a108 WCBfor dual purposeoperation.
The only difference between the "A" model
and the "B’ model is the Cylinder (19) part
number. "A" modelsuse P/N513398 for item
(19). All other parts on the part list is the same
as a "B" model element.
1.2.3 WCB Models with "G" (146XXXG)
designator have bonded standard lining.
To replace see table 12 in section 6.2 and order
