V-Belt
Specialty V-belts
When equipment calls for metric precision, you need a belt that
not only measures up, but one that won’t get lost in translation.
Metric belts belts are engineered to universal metric profiles,
but manufactured by Continental ContiTech in North America,
so you do not have to go elsewhere to get them.
Strong, flexible and able to work in wide temperature ranges,
metric belts replaces many common metric cross section belts
such as XPZ, XPA, SPA, XPB, SPB, XPC and SPC.
Double-V or Hex belts
A variation of the Classical belt, Hex belts come in AA, BB, CC
or a deep CCP cross section. These belts transfer power from
either side in serpentine drives. A drive design using Hex belts
is more complicated and engineering manuals should be
consulted when replacing or troubleshooting these drives.
Fractional Horsepower belts (FHP)
The 3L, 4L and 5L light-duty FHP belts are part of the
V-belt line also. As the name implies, these belts are used
solely on drives of 1 horsepower or less.
Narrow V-belts
Effectively handling drives from 1 to 1,000 horsepower, these
belts rank high in horsepower-hours per dollar, the ultimate
measure of drive value. The Narrow belt cross sections (3V, 5V
and 8V), offer higher power capacity for any sheave size
and weight.
The Narrow or “wedge” design provides more tensile member
support than Classical V-belts. Narrow belts handle an
equivalent load, but with narrower face width and smaller
diameters than the traditional Classical V-belts. These features
allow the use of smaller belts or fewer belts to transmit the load,
an important advantage if your goal is to maximize power
transmission efficiency by reducing drive weight and size.
Classic V-belts
The most widely used V-belts are A, B, C and D Classical belts.
Used more out of habit and convenience than design, these
belts can handle fractional to 500 horsepower drives, usually
at the lowest cost. However, they occupy more space and the
drives weigh more than Narrow belt drives. Also, Classical belts
are usually less efficient than Narrow belts. But their versatility
and wide range of sizes and types make them an attractive
alternative to wedge belts.
Many Classical belts are used for replacement because it is
considered too costly to replace sheaves when upgrading from
Classical to Narrow or other belt types. Therefore, when
replacing Classical sheaves, it is an opportune time to upgrade
to Narrow or other belt types.
V-Belts
Not only traditional Classical and
Narrow profiled belts, but also
Double-V and FHP belts
When synchronization or timing is not required, V-belts make
an excellent low-cost, quiet and efficient means of transmitting
power. However, not all V-belts perform the same. Depending
on your application and your objectives, some V-belts will be
better at getting you closer to your end goal.
