The sheave features a 6.68-inch outside diameter with a 6.5-inch belt pitch diameter for 5V belts, a 6.0-inch pitch diameter for A belts, and a 6.4-inch pitch diameter for B belts. It accepts B-style QD bushings and accommodates bore diameters from 5\/8 inch up to 2-1\/4 inches, making it adaptable to a range of shaft sizes. Cast iron construction provides the durability required for continuous-duty HVAC, industrial fan, and pump drive applications. The part weighs 9.1 pounds.\u003c\/p\u003e\n\u003cp\u003eThis sheave is suited for residential and commercial HVAC systems, industrial blower assemblies, pump drives, and similar belt-driven equipment where a two-groove, QD-mounted configuration is specified. The quick-detachable bushing design simplifies installation and removal on the shaft without specialized pulling equipment. Applications typically include air handling units, centrifugal fans, and direct-replacement drive upgrades where 5V, A, or B belt sections are already in use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTwo grooves accept 5V, A, and B cross-section V-belts\u003c\/li\u003e\n  \u003cli\u003e6.68-inch outside diameter with a 6.5-inch 5V belt pitch diameter\u003c\/li\u003e\n  \u003cli\u003eBore range from 5\/8 inch to 2-1\/4 inches via B-style QD bushing\u003c\/li\u003e\n  \u003cli\u003eQuick-detachable (QD) bushing mount for fast, secure shaft installation and removal\u003c\/li\u003e\n  \u003cli\u003eCast iron construction for durability in continuous-duty drive applications\u003c\/li\u003e\n  \u003cli\u003eUNSPSC Code 31171804 for procurement and sourcing compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or upgrade sheave for two-groove V-belt drive systems using 5V, A, or B belt sections with B-style QD bushings.
