Browning 3694528 4 Groove Qd V Belt Sheave 6.48 in Od

Product Description

The BROWNING 3694528 is a four-groove, Quick Detachable (QD) bushed V belt sheave designed for industrial and commercial drive applications. Constructed from cast iron, this sheave accepts a B-style QD bushing and accommodates bore diameters from 5/8 inch up to 2-1/4 inches, giving installers flexibility when matching to a shaft size. The outside diameter measures 6.48 inches, and the 5V belt pitch diameter runs 6.3 inches. With a finished weight of 11.5 pounds, this is a solid, production-grade component suited for HVAC fan drives, blowers, pump drives, and other belt-driven mechanical systems.

This sheave is intended for use with 5V, A, and B cross-section V belts in four-groove drive configurations. It is a common choice for commercial HVAC air handler fan drives, industrial blowers, and pump assemblies where a QD bushing system is specified. The QD bushing interface allows for straightforward installation and removal without specialized tooling, making it practical for field service and preventive maintenance work. Bore range compatibility makes it adaptable across a range of shaft sizes encountered in commercial mechanical systems.

Installation Notes

Installation and removal should be performed by a qualified millwright or mechanical technician. De-energize and lock out all power to the driven equipment before beginning work. Verify shaft diameter falls within the 5/8 inch to 2-1/4 inch bore range before ordering the matching QD bushing. Ensure proper belt tension and sheave alignment after installation to prevent premature belt and bearing wear.
