Description
This 4B300R sheave features four grooves, is 30.35″ in diameter, and is designed to use an R1 bushing. Split Taper style sheaves offer a wider selection of bore sizes versus a standard “fixed” bore style sheave. Also because they are a two-component part if one component fails the entire part doesn’t need to be replaced. All of our sheaves are manufactured out of an extremely durable cast iron, are dynamically balanced at the factory, and are phosphated then painted for corrosion resistance. Additionally, we stock a full line of premium A, 4L, B, 5L, AX, BX, AA, and BB belts, R1 bushings, shafting, key-stock, motors, gearboxes, bearings, and much more!
