The storage of power transmission belts is of interest to users and
distributors as well as manufacturers. Under favorable storage
conditions, good quality belts retain their initial serviceability
and dimensions. Conversely, unfavorable conditions can adversely
affect performance and cause dimensional change. Good storage
facilities and practices will allow the user to achieve the most value
from belt products.
Power transmission belts should be stored in a cool and dry
environment with no direct sunlight. When stacked on shelves,
the stacks should be small enough to avoid excess weight on
the bottom belts which may cause distortion. When stored in
containers, the container size and contents should be sufficiently
limited to avoid distortion, particularly to those belts at the
bottom of the container.
Do not store belts on floors unless a suitable container is
provided. They may be susceptible to water leaks or moisture or
otherwise damaged due to traffic.
Do not store belts near windows which may permit exposure to
sunlight or moisture. Do not store belts near radiators or heaters
or in the airflow from heating devices.
Do not store belts in the vicinity of transformers, electric motors,
or other electrical devices that may generate ozone. Also avoid
areas where evaporating solvents or other chemicals are present
in the atmosphere.
Do not store belts in a configuration that would result in bend
diameters less than the minimum recommended sheave or
pulley diameter for normal bends and not less than 1.3 times the
minimum recommended diameters for reverse bends. (Refer
to appropriate RMA-MPTA-RAC Standards for minimum
recommended diameters.)
V- b e lt s
A common method of storing belts is to hang them on pegs or
pin racks. Very long belts stored this way should use sufficiently
large pins or crescent-shaped “saddles” to prevent their weight
from causing distortion. Long V-belts may be “coiled” in loops
for easy distortion-free storage. The following is a guide to the
maximum number of coils for extended storage time.
