As technology advances and systems get smaller and smaller
so too does the desire for smaller drive pulleys. Though size can be decreased, it is important
to ensure that none of the drive pulleys fall below the minimum recommended
diameters given this can result in shortened belt life, premature belt wear,
and overall poor drive performance. Below are the minimum pulley sizes for
both V-belt sheaves and Synchronous sprockets.
It is still important however to check with the motor or
gearbox manufacturers to ensure that these small pulley sizes do not result in
excessive shaft load or fall below any NEMA (National Electric Motor Association) standards which could prove to be detrimental to the drive components. For any
