Joined V-belts, Synchronous belts,
V-ribbed belts
Like V-belts, these belts may be stored on pins or saddles
with precautions taken to avoid distortion. However, belts of
these types, up to approximately 120 inches (3,000mm),
are normally shipped in “nested” configuration and it is
recommended that the belts be stored in this manner as well.
Nests are formed by laying a belt on its side on a flat surface
and placing as many belts inside the first belt as possible
without undue force. When the nests are tight and stacked with
each rotated 180° from the one below, they may be stacked
without damage.
Belts of these types over approximately 120 inches (3,000mm),
may be “rolled up” and tied for shipment. These rolls may be
stacked for easy storage. Care should be taken to avoid small
radii, which could damage the belts.
Variable speed belts
A common method of storing belts is to hang them on pegs or
Variable Speed belts are more sensitive to distortion than most
other belts and it is not recommended that these belts be
hung from pins or racks. They should be stored on shelves.
A common method for packaging for shipment is the use of a
“
sleeve” slipped over the belt. Variable Speed belts should be
stored in these sleeves and may conveniently be stacked on
shelves with the aid of the sleeves.

Effects of storage
The quality of belts has not been found to change significantly
within seven years of proper storage at temperatures less than
85
°F (30°C) and relative humidity below 70%. Also there must
be no exposure to direct sunlight.
If the storage temperature is increased beyond 85˚F (30°C),
then the storage limit for normal service expectancy should
be reduced. From a base of 7 years at 85°F (30°C), the
storage limit should be reduced by one-half for each 15˚F (8°C)
increase in temperature. Under no circumstances should belts
be exposed to storage temperatures above 115°F (46°C).
With a significant increase in humidity, it is possible for fungus
or mildew to form on stored belts. This does not appear to
cause serious belt damage, but should be avoided if possible.
Equipment using belts is sometimes stored for prolonged
periods (six months or more) before it is put in service or
during other periods when it is idle. It is recommended that
the tension of the belts be relaxed during such period and
that equipment storage conditions should be consistent with
the guidelines for belt storage. If this is not possible, the belts
should be removed and stored separately.
