General Information
All Optibelt V-belts are manufactured with
carefully chosen raw materials utilising
continually updated manufacturing meth-
ods.
The modernisation of production process-
es, large scale laboratory testing, and the
careful control of the basic materials will
guarantee a consistent quality for every
Optibelt power transmission component.
Product function, efficiency and durability
are of major importance to Optibelt.
Characteristics
Oil resistant
The oil resistant cover of the belt protects
it from contamination by mineral oil /
grease splash. Contamination by animal
or vegetable oil or water solvent cutting oil
will reduce belt life. In extreme cases the
use of our special construction is re-
commended.
Heat resistant
Standard construction Optibelt V-belts will
operate in ambient temperatures up to
+70 °C / +158 °F.
Higher ambient temperatures will lead to
premature ageing and subsequent belt
failure. In this case our special construc-
tion XHR or Super X-POWER is recom-
mended.
Cold resistant
Standard construction Optibelt V-belts will
perform satisfactorily in ambient tem-
peratures down to
–40 °C / –40 °F for wrapped construction
and
–30 °C / –22 °F for raw edge construction.
Under critical conditions practical tests
are necessary.
Antistatic
In order to comply with product safety
requirements the specific antistatic prop-
erties of any V-belts must be tested to ISO
1813. A test certificate will be issued and
a 20% surcharge will be applied.
Antistatic V-belts should be specified sep-
arately to ensure that the correct certifi-
cation is carried out.
Intermediate Lengths
Intermediate lengths can be produced for
wrapped V-belts except for lengths of up
to 1800 mm, where we have to check our
possibilities on request. A minimum quan-
tity for each length is required. We reserve
the right of over- and undersupplies.
The compliance with special tolerances is
charged on a time and material basis.
Special Constructions
The following are examples of surcharges
applicable to special constructions.
Smooth running – LR
20%
Extra oil resistant
50%
Extra heat resistant – XHR
20%
V-belts with
patterned top surface – PKR
200%
Prices for other constructions on request.
Observance of special tolerances will be
charged according to actual cost.
Non standard lengths and special
constructions for wrapped V-belts
In the event that fewer production sets than
normal are required for a particular special
construction wrapped belt (normal 3 pro-
ductionsets) then the followingsurcharges
apply:
2 production sets:
20% surcharge
1 production set:
40% surcharge
Please note that minimum production set
quantities may vary for certain special
construction belts. If in doubt ask your
Optibelt contact.
Multiple Belt Drives
Requirements for drives using sets of belts
often demand belt measurement to form
the sets. Optibelt S=C PLUS and M=S
belts do not require belt measurement or
re-measurement to form sets.
