Browning 1002641 Qd Bushed V-belt Sheave 3 Groove

Product Description

The BROWNING 1002641 is a three-groove, quick-disconnect (QD) bushed V-belt sheave designed for industrial and commercial HVAC drive systems. It accepts 5V, A, and B series belts and features an 11.35-inch outside diameter with a belt pitch A diameter of 10.6 inches and a belt pitch B diameter of 11.0 inches. Bore range runs from 3/4 inch minimum to 2-11/16 inch maximum, accommodating a wide variety of shaft sizes. Constructed from cast iron, this sheave delivers the rigidity and wear resistance required in belt-driven blower, fan, and pump applications. Installation relies on the Q1-style QD bushing system, allowing field installation and removal without special tooling. HVAC technicians and mechanical contractors are the primary installers.

This sheave is suited for belt-driven fan and blower assemblies found in commercial air handling units, industrial ventilation systems, and heavy-duty HVAC equipment. The three-groove configuration supports multi-belt drive arrangements, which distribute load and reduce belt slippage under high-torque startup conditions. The QD bushing design makes it practical for retrofit and replacement work where shaft access is limited, and the broad bore range allows a single part to fit multiple drive shaft diameters encountered in the field.

Compatibility

Compatible with 5V, A, and B series V-belts. Designed for use with Q1-style quick-disconnect bushings. Consult the bushing bore chart to confirm shaft diameter compatibility before ordering.

Installation Notes

Installation and removal should be performed by a qualified HVAC technician or millwright. Disconnect and lock out all power to the drive system before handling the sheave or bushing. Follow the QD bushing manufacturer torque sequence for the bushing cap screws to ensure proper seating and concentricity. After installation, verify belt alignment and tension before returning the drive to service.
