Dura-Belt rough green
round urethane belts are made from 88A durometer urethane cord.
The hard, rough surface is texturized to provide a lower coefficient
of friction (0.4) so that belts can slip a little in pulleys
without overheating and abrading. Rough green round belting is
also ideal for use on slider beds or where accumulation occurs.
Rough green urethane cord is often used in paper moving, printing,
and postal applications because the rough surface can catch the
edge of a sheet of paper and push it along.
People often think that
the rough texturized surface will grip pulleys better and slip
less than smooth belts, but surface contact area is what counts
with urethane belting. The more surface contact, the greater
the coefficient of friction. Therefore, smooth belts will grip
better, but if forced to slip, they tend to overheat and stretch
or abrade. Rough green belting can help overcome this problem.
- Rough surface effectively makes belts more abrasive resistant.
- Not food grade -- rough surfaces are not USDA/FDA approved.
- Replaces Polycord® belts and Green-Go 90 TM round urethane
belting.
- Available in either rough or matte surface (slightly less
rough).
- Also available in softer 86A durometer for applications where
more grip is desirable.
- Available with polyester cord reinforced for applications
that require less stretching.
- Superior water resistance (hydrolytically stabilized)
-- ideal for washdown applications.
