3V Eight-Groove Taper Bushed Sheaves
3V series eight-groove taper bushed sheaves are manufactured for
3V, 3VX, banded 3V, and banded 3VX belts. They range from 4.75" to 33.50" in diameter. Depending on the sheave size they are made to use a Q2, R1 or S1 split-taper bushing, which we also stock. The majority of our eight-groove 3V split taper sheaves are manufactured from a high-strength grade 35 cast iron, are phosphate-coated and painted for anti-corrosion, and all of them are balanced at the factory for smooth machinery operation.
