It accepts A and B series belts, with a belt pitch diameter of 2.8 inches for A-series and 3.2 inches for B-series. The outside diameter measures 3.55 inches. Bore range runs from 3\/8 inch minimum to 1-1\/2 inch maximum, accommodating the H-style QD bushing for fast, accurate shaft mounting. Cast iron construction provides durability in mechanical drive applications. HVAC and industrial technicians install this sheave on fan and blower assemblies where compact, adjustable-bore sheaves are required.\u003c\/p\u003e\n\u003cp\u003eThis sheave suits residential and light commercial HVAC blower drives, exhaust fans, and general mechanical power transmission setups. It is compatible with standard A and B section V-belts and fits any shaft within the bore range when the appropriate H-style QD bushing is used. The single-groove design makes it well-suited for straightforward one-belt drive configurations on air handlers, furnace blowers, and similar equipment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSingle-groove design accepts A and B series V-belts\u003c\/li\u003e\n  \u003cli\u003eOutside diameter of 3.55 inches for compact drive applications\u003c\/li\u003e\n  \u003cli\u003eBelt pitch diameter of 2.8 inches (A-series) and 3.2 inches (B-series)\u003c\/li\u003e\n  \u003cli\u003eBore range from 3\/8 inch to 1-1\/2 inch via H-style QD bushing\u003c\/li\u003e\n  \u003cli\u003eCast iron construction for wear resistance and long service life\u003c\/li\u003e\n  \u003cli\u003eQD bushing mount allows quick installation and removal without special tooling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with A and B series V-belts and H-style QD bushings.
