Browning 1027002 Single Groove Sheave 6-1/4 in Od

Product Description

The BROWNING 1027002 is a finished bore single groove sheave designed for belt-drive power transmission applications in HVAC, industrial, and mechanical systems. Manufactured from cast iron, this sheave features a 7/8 inch finished bore and a 6-1/4 inch outside diameter. The groove accepts standard B-section or A-section V-belts, with a belt pitch diameter of 6.0 inches for B/A type belts and 5.66 inches for 3L type belts. The overall length through the bore is 1-5/32 inches. Installation is handled by HVAC technicians, millwrights, and mechanical contractors during blower and fan assembly work.

This sheave is suited for single-groove V-belt drive configurations found in residential and light commercial air handling units, blower assemblies, exhaust fans, and general-purpose power transmission equipment. The finished bore accepts a 7/8 inch shaft directly without additional machining. It is compatible with standard B-section and A-section V-belts as well as 3L fractional horsepower belts, making it a practical choice for fan and blower drive replacement and new installations.
