Built as a two-piece bushed sheave, it uses an H-style bushing (sold separately) that slides over the shaft and clamps down as the bushing bolts are tightened — giving a secure, concentric fit on a range of shaft sizes without machining. Two grooves let it carry a matched pair of belts for higher-load or two-belt drives. Available in 21 outer diameters from 3.05\" up to 14.25\".\u003c\/p\u003e\u003ch3\u003eKey specifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eBelt section: A \/ 4L (1\/2\" top width), also runs AK \/ 3L \/ 4LK\u003c\/li\u003e\n\u003cli\u003eGrooves: 2 (double groove)\u003c\/li\u003e\n\u003cli\u003eMaterial: fine-grained cast iron, statically balanced\u003c\/li\u003e\n\u003cli\u003eBushing: takes an H-style bushing (required, sold separately)\u003c\/li\u003e\n\u003cli\u003eFinish: painted, individually packaged\u003c\/li\u003e\n\u003cli\u003eOuter diameter: 3.05\" – 14.25\" depending on size selected\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTypical applications\u003c\/h3\u003e\u003cp\u003eUsed throughout air compressors, blowers, fans, pumps, conveyors, and general power-transmission drives where a two-belt A\/4L drive is specified for higher load capacity or smoother power delivery between a motor and driven equipment.
