Browning 1042589 Qd Bushed V Belt Sheave 1 Groove 8.25 in

Product Description

The BROWNING 1042589 is a single-groove, QD (Quick Detachable) bushed V-belt sheave designed for industrial and commercial belt-drive applications. Constructed from cast iron, this sheave accepts an H-style QD bushing, allowing fast installation and removal without special tooling. The outside diameter measures 8.25 inches, with a belt pitch A diameter of 7.5 inches and a belt pitch B diameter of 7.9 inches. Bore diameter range runs from 3/8 inch minimum to 1-1/2 inch maximum, accommodating a wide variety of shaft sizes. The part weighs 4.65 pounds. HVAC technicians, millwrights, and mechanical contractors install this type of sheave on fan drives, blower systems, and general power-transmission equipment.

This sheave is compatible with A-section and B-section V-belts, making it a versatile option across residential and light commercial HVAC blower assemblies, industrial fan drives, and other belt-driven rotating equipment. The QD bushing design enables precise shaft alignment and repeatable torque retention, which is especially useful in multi-unit installations or planned-maintenance environments where sheaves are replaced on a regular schedule.

Installation Notes

Installation and removal must be performed by a qualified millwright, HVAC technician, or mechanical contractor. Always de-energize the drive system and lock out the power source before removing or installing sheave components. Verify shaft diameter falls within the 3/8-inch to 1-1/2-inch bore range before selecting the appropriate H-style QD bushing. Follow the bushing manufacturer torque sequence for the bushing cap screws to ensure proper seating and shaft grip.
