Dunlop UsFlex® is the world standard in heavy-duty
industrial conveyor belting. Its innovative, straight-warp car-
cass construction surpasses traditional multiply belts in virtu-
ally every respect, creating a belt that has outstanding opera-
tional performance over a long life span. A single UsFlex
ply more than matches the strength of several traditional
multiply layers.
The UsFlex construction consists of extra-heavy strands of
polyester running lengthwise, with nylon running crosswise.
The strands are completely straight in both directions and are
therefore not intertwined unlike traditional woven carcasses.
This results in maximum protection of the warp through the
weft, with minimal stretch, both lengthwise and crosswise.
As there are no multiple plies, the result is a lightweight belt
with maximum tensile strength.
DUNLOP USFLEX® CONVEYOR BELTS
UNRIVALLED IMPACT, RIP AND TE AR RESISTANCE
superior impact resistance
When compared to conventional multiply belts with a similar
tensile strength, UsFlex stands out with its superior impact
resistance. The maximum impact energy of a single ply UsFlex
type 630/1 is comparable to that of a 4-ply EP belt type 1600/4.
superior rip resistanceUsFlex has a rip resistance that is more than four times
greater than conventional multiply belts that have a
similar tensile strength. The rip resistance is not only superior
in relation to the multiply EP belts, but also when compared
to Solid Woven.
superior tear resistance
The tear resistance of UsFlex also leaves conventional
multiply belts with a comparable tensile strength far behind.
The tear resistance is measured according to the international
ISO 505 standard.
some of the key features of usflex include:
• UNRIVALLED IMPACT, RIP AND TEAR RESISTANCE
• HIGH STRENGTH
• EXCELLENT LOAD SUPPORT
• OUTSTANDING TROUGHABILITY
• LIGHTWEIGHT

LOWER COST PER TON.. .
AND THEREFORE MORE COST-EFFECTIVE FOR NUMEROUS APPLICATIONS.
Because of its outstanding operating performance and lifespan. UsFlex is an extremely cost-effective solution. A lighter
belt type can be used in many applications due to its excellent
operational characteristics and finger splice efficiency. The
combination of these factors has been proven to result in
exceptionally low operating costs per ton.
value for money – guaranteed
UsFlex has been a proven success for many years throughout
the world. For example, a large stone quarry had been using
traditional conveyor belts for the crusher area, which is the
most demanding of applications. The average life span of these
belts had been 4 months. As a consequence the belts were
replaced with a heavier type of multiply EP belt resulting in a
marked reduction in operational costs but with a life span of
less than 12 months. After a thorough inspection by Dunlop’s
Application Engineers, UsFlex was recommended and
installed with amazing results. After 3 years, the UsFlex belt
was still successfully operating, resulting in a reduction in cost
per ton of more than 80%.
usflex with finger splice – producing exceptio-
nal operating performance and durability
In conventional multiply belts, the strength of the belt is often
determined by the strength of the splice. UsFlex puts an end
to this traditional weak spot. Instead of using the traditional
hot or cold vulcanised step splice, the finger splice method can
be used with the most spectacular results. The Dunlop finger
splice has an efficiency factor of more than 90%. This is largelydue to the actual splice materials, which have been specifically
developed for UsFlex. By comparison, a step splice has an
efficiency of 66% for a 3-ply belt type. Making a good finger
splice is actually quite easy to learn but it does require
technical training. At Dunlop we are more than happy to
share our knowledge and experience with our customers.
Although UsFlex with finger splice is supremely reliable, the
conventional ‘step’ and ‘mechanical’ splice joints can also be
used. Please ask our Application Engineering department for
the best splicing joint for your application.
usflex – the best possible guarantee for reliability in a wide variety
of industries including:• QUARRIES
• MINING
• CEMENT
• WOOD, PAPER & PULP
• RECYCLING
It is for very good reason that we call Dunlop UsFlex “the world sta ndard in industrial conveyor belts”. With its
robust construction, it is the ideal conveyor belt for particularly heavy applications. The low cost per ton also makes
UsFlex an especially cost-effective alternative for numerous applications in a wide range of industries.
* Diameter for belt loads from 60% up to 100%. For lower loads a smaller diameter can also be suitable.** The load support of a belt is a factor of the belt width, belt strength and bulk material density. The table indicates the limits for correct load

carcass thickness and drum diameters
The carcass thickness of both UsFlex I & II is similar or smaller
than those of comparable multiply EP conveyor belts from
Dunlop. For example, the UsFlex 400/1 carcass has a thickness
of 2.4 mm, compared to 3.0 mm for the EP 400/3. As a result,
the required drum diameter may be smaller in some cases.
For more detailed information please also refer to the datatable shown in this brochure.
cover qualities
UsFlex is available in the RS (extra wear resistant) cover
quality. Other qualities, such as oil, fire and heat resistant
covers are available upon request.
Belt selection - The correct choice of belt type and cover
quality is dependent on several different factors. To enable the
correct belt type to be chosen, it is very important to provide
as much information as possible. The final choice from the
available options for each application will depend on the actual
working conditions, which may differ quite significantly from
location to location.
