WAS-80 is a
clutch facing material
having a non – metallic
woven asbestos base
impregnated with an
infusible bond which
gives it good durability and
resistance to fade. It
possesses a medium
coefficient of friction and
is capable of satisfactory
permormance under
reasonably high clutch
temperatures.
It is recommended for
general engineering
requirements where
exigencies of exceptional flange width or other dimensions force the
adoption of facings in two or more segments. It is intended for use
under dry conditions of operations. It is available in flat sheet form.
APPLICATIONS
INDUSTRIAL CLUTCHES: General engineering application. Tractor main engine clutches.
TECHNICAL DATA:
Friction

CLUTCH DESIGN:
The applied load in a clutch is not transmitted as efficiently as in a brake
and the full effective torque radius is not always developed. It is usual,
therefore, to use a lower design friction value for a clutch than for a
brake with similar torque characteristics. The coefficient of friction for
design should be based upon severity of the application and the maximum
anticipated operating temperature. Normal engineering practice should
be followed in applying an appropriate safety factor to the torque
requirements of the unit.

Maximum temperature : 3500c
Maximum continuous temperature : 1250c

CLUTCH DESIGN:
A friction clutch should be capable of transmitting without slip, the
maximum torque that can be applied to it once the clutch is fully engaged.
The applied load in a clutch is not transmitted as efficiently as in brake
and the fully effective torque radius is not always developed. This
should be borne in mind when selecting the design co-efficient of friction,
also taking into account the severity of the application and maximum
operating temperatures of clutch surface. Normal engineering practice
should be followed in applying an appropriate safety factor to the torque
requirements of the unit.
