Although we call it by two different names, we only make one size of twin idler pulley. Customers use this dual sheave with many different belt cross-sections, including 1/16” through 3/8” (1.5mm through 9.5mm) belts. When our 83A/85A durometer belts are stretched tight, they are soft enough to conform to the pulley groove. Therefore, the groove radius is not critical. Under normal loads the belts will not slip.
Our plastic pulleys and sheaves are made from nylon reinforced with fiberglass and ABEC-1 ball bearings. This nylon material is easy to machine on a lathe, and there is no fiberglass dust, as long as you do not grind it. We can cut down the flanges, enlarge the grooves and/or add grooves (e.g. Poly-Vee grooves) at a slight extra cost.
