Browning 3693710 Qd Bushed V Belt Sheave 1 Groove

Product Description

The BROWNING 3693710 is a quick-detachable (QD) bushed V belt sheave designed for power transmission applications in HVAC, industrial, and mechanical drive systems. It features a single groove configuration with a 7.08-inch outside diameter and accepts a range of bore sizes from 5/8 inch to 2-1/4 inch, allowing broad compatibility with standard B-style QD bushings. Rated for use with A, B, and 5V belt profiles, this sheave is a direct fit for blower and fan drive assemblies where reliable torque transfer is required. Licensed HVAC mechanics and millwrights typically install this component during motor-to-blower drive setups or sheave replacements.

This sheave is suited for residential and light commercial HVAC air handler fan drives, pump drives, and general mechanical power transmission installations. The QD bushing mount simplifies installation and removal without specialized tooling, making it practical for field service and equipment room work. The wide bore range accommodates various shaft sizes commonly found in blower motors and belt-driven fan assemblies. No specific compatible model numbers were provided in the product data.
