Product Description

The BROWNING 3693611 is a single-groove, Quick Detachable (QD) bushed V-belt sheave designed for industrial belt drive applications. Constructed from iron, it features a 5.08-inch outside diameter and accepts a B-style QD bushing with bore diameters ranging from 5/8 inch to 2-1/4 inches. The sheave is compatible with 5V, A, and B belt trade sizes, making it a versatile component for HVAC blower drives, fan systems, pump drives, and other mechanical power transmission setups. Installation is performed by qualified mechanical or HVAC technicians and the unit weighs 2.8 pounds.

This sheave is suited for use in commercial and industrial belt drive configurations where a single-groove V-belt arrangement is required. It is commonly installed on blower assemblies, centrifugal fans, and pump units in HVAC systems and light industrial equipment. The QD bushing design allows for tool-assisted bore sizing within the specified range, reducing the need for stocked inventory of fixed-bore sheaves across multiple shaft sizes. Applicable belt pitch diameters are 4.9 inches for 5V belts, 4.4 inches for A belts, and 4.8 inches for B belts.
