Carrying the BK140H designation, this sheave accepts an H-style QD bushing and accommodates bore diameters from 0.375 inches up to 1.5 inches, making it adaptable to a range of shaft sizes without requiring a custom bore. The outside diameter measures 13.75 inches, with a belt pitch A diameter of 13.0 inches and a belt pitch B diameter of 13.4 inches. Licensed HVAC, mechanical, and industrial service technicians install this type of sheave on fan and blower assemblies where belt drive efficiency and shaft alignment are critical.\u003c\/p\u003e\u003cp\u003eThis sheave is suited for single-groove V-belt drive systems used in commercial and industrial HVAC air handlers, exhaust fans, blowers, and general power transmission equipment. The QD bushing design allows for straightforward installation and removal without special tooling, reducing downtime during preventive maintenance or component replacement. It is sized for applications requiring a large-diameter drive pulley, which lowers belt speed and output RPM relative to the motor sheave, a common configuration in belt-driven fan systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSingle-groove QD bushed design accepts H-style quick-disconnect bushing for tool-friendly installation and removal\u003c\/li\u003e\n\u003cli\u003eOutside diameter of 13.75 inches suits large-diameter drive pulley configurations\u003c\/li\u003e\n\u003cli\u003eBelt pitch A diameter of 13.0 inches and belt pitch B diameter of 13.4 inches\u003c\/li\u003e\n\u003cli\u003eBore range from 0.375 inches to 1.5 inches accommodates multiple shaft sizes\u003c\/li\u003e\n\u003cli\u003eBK140H sheave designation for direct cross-reference and replacement sourcing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or upgrade sheave for single-groove V-belt drive systems using H-style QD bushings.
