13” diaphragm style 3250 lb. Pressure plate offers
maximum holding power with easy pedal effort.
ceramic buttons will be facing the center plate. This will
increase the holding power as well as increase the temperature
capabilities to the intermediate plate.
discs are a dampened free travel design similar to the semi
clutch to help reduce gear roll over.
one of a kind dampened center plate was designed to eliminate
rattle when clutch is released.
in the clutch industry! We have developed organic friction
in a button form allowing us to create a multi friction,
dual disc clutch. The organic will be facing the pressure
plate and flywheel for smooth engagement yet still offers
superior holding power.
Bend Clutch heard the call for the organic dual disc clutch
but wanted to offer the best in both durability and drive
ability. How do they achieve that? In our 50 years of experience
we knew that running an all organic dual disc would have it's
problems. The intermediate (center) plate is approximately
½” thick whereas the pressure plate and flywheel
castings are three times that. Running two friction surfaces
on one thin casting will increase the temperature to that
casting. Organic burn point is approximately 550 degrees whereas
ceramic can reach 1,100 degrees. The immediate engagement
points when the clutch is released for takeoff are the outside
points of a dual disc clutch, pressure plate and flywheel.
Being that there is only one friction surface running to these
two points, and the fact that the pressure plate and flywheel
castings are much thicker than the center plate, the temperatures
cannot reach that of the center plate. This is why organic
will work to the pressure plate and flywheel and not to the
Bend Clutch feels they have reached a milestone in the clutch
industry and hope that you will enjoy our hard work at being
the industry leader in research and development of clutches
for the diesel market.
