Browning 1042431 Qd V Belt Sheave 1 Groove 4.25 in Od

Product Description

The BROWNING 1042431 is a quick-detachable (QD) bushed V belt sheave designed for single-groove belt drive applications in HVAC, industrial, and mechanical systems. It features an H-style bushing mount and an outside diameter of 4.25 inches, with a belt pitch A diameter of 3.5 inches and a belt pitch B diameter of 3.9 inches. The bore accepts shaft diameters from 3/8 inch up to 1.5 inches, making it adaptable across a range of shaft sizes. Licensed HVAC technicians and mechanical contractors typically install this sheave when configuring or replacing belt-driven blower and fan assemblies.

This sheave is suited for residential and light commercial belt drive systems where a single-groove V belt configuration is required. Common install scenarios include air handler blowers, exhaust fans, and other motor-to-load belt drive setups that use A-section or comparable V belts. The H bushing style allows the sheave to be paired with a separately sourced QD H bushing to achieve the desired final bore diameter within the specified range.
