A three-groove, B-section cast iron V-belt sheave built as a two-piece bushed sheave. It accepts a standard SD-series QD-style taper bushing (sold separately), letting you match one sheave to a range of shaft sizes for a secure, concentric, easily serviced mount. Ideal for triple-belt drives that need extra load capacity on air compressors, pumps, fans, and other industrial equipment.
