Variable Speed Pulleys (VPS), Economical Fractional Horsepower (FHP) Pulleys combine all the cost-saving features of glass reinforced nylon with steel shafts and steel-clad flanges for greater wear resistance. Speed range is infinitely variable within standard ratio limits. All pulleys are spring-loaded and color-coded to indicate spring pressure.
Standard sizes and types, dimensions and spring pressures are listed below.
All Variable Speed Pulleys are supplied with setscrews.
VPS Pulleys are shipped with the blue, heavy strength spring unless another strength spring is requested.
On the Model VPS-10 Pulley, we recommend that only the heaviest blue spring be used if the pulley is to be run with a 3/8-inch width V-belt.
All springs are carried in stock.
