Product Description

The BROWNING 1002286 is a three-groove, QD bushed V belt sheave designed for power transmission applications in HVAC, industrial, and mechanical drive systems. It accepts standard A and B section V belts and uses a Q1 bushing style for quick, secure installation and removal without special tools. The outside diameter measures 7.35 inches, the belt pitch diameter for A section belts is 6.6 inches, and the belt pitch diameter for B section belts is 7.0 inches. Bore range spans 3/4 inch minimum to 2-11/16 inch maximum, giving installers flexibility across a wide range of shaft sizes. Total unit weight is 13.9 pounds.

This sheave is suited for use in belt-driven blower and fan assemblies commonly found in commercial and residential HVAC air handling units, industrial ventilation systems, and general mechanical drive equipment. The three-groove configuration supports multi-belt drive arrangements that require higher torque capacity or redundancy. It is typically installed by HVAC technicians, millwrights, and mechanical contractors during new equipment setup or drive system replacement service.
