Browning 3695194 Qd Bushed V Belt Sheave 3 Groove 4.48 in

Product Description

The BROWNING 3695194 is a three-groove, Quick Detachable (QD) bushed V belt sheave designed for use with 5V, A, and B cross-section belts in industrial and commercial HVAC drive applications. Manufactured from iron, it features a P1 bushing style and accepts bore diameters ranging from 0.5 inches to 2.4375 inches, allowing adaptation to a wide range of shaft sizes without custom machining. The outside diameter measures 4.48 inches, with belt pitch diameters of 4.3 inches for 5V belts, 3.8 inches for A belts, and 4.2 inches for B belts. At 4.8 pounds, it is a solid, field-proven component suited for blower and fan drive systems. HVAC mechanics and millwrights are the typical installers.

This sheave is used in belt-driven blower assemblies, supply and return air fan systems, and general industrial drive trains where multiple belt groove capacity and QD bushing convenience are required. The three-groove configuration supports multi-belt drive setups common in larger air handling units and commercial rooftop equipment. The P1 QD bushing style simplifies installation and removal, making it well suited for applications where periodic service or belt replacement is expected.

Installation Notes

Installation should be performed by a qualified HVAC technician or millwright. Disconnect and lock out all electrical power to the drive system before removing or installing any sheave or belt components. The QD bushing must be seated fully and fasteners tightened evenly before applying belt tension. Verify belt alignment across all grooves after installation to prevent premature wear.
