Guiding & support sheaves

These sheaves are cast in an aluminium alloy prior to being machined to precise tolerances. In many applications they offer a reasonably priced alternative to drums. The distance between guiding and supporting sheaves can be selected such that the steel belt does not sag excessively when under pretension stress. This generally results in a distance of 200–300 mm. The number of sheaves must be such that the driving force can be reliably transmitted to the steel belt.
