Browning 3693777 Qd Bushed V-belt Sheave 1 Groove 9.68 in Od

Product Description

The BROWNING 3693777 is a single-groove, Quick Detachable (QD) bushed V-belt sheave designed for industrial belt drive applications. It accepts 5V, A, and B cross-section V-belts and features a 9.68-inch outside diameter with a 9.5-inch belt pitch diameter for 5V belts. The bore range runs from 5/8 inch minimum to 2-1/4 inch maximum, accommodating a wide range of shaft sizes through a Type B QD bushing. Cast iron construction provides the durability and balance required for continuous-duty rotating equipment. Licensed HVAC mechanics, millwrights, and mechanical contractors install this sheave in fan, blower, and pump drive assemblies.

This sheave is suited for single-belt drive configurations on centrifugal fans, blowers, air handling units, and pump systems found in commercial and light industrial settings. The QD bushing system allows fast installation and removal without special tooling, making it practical for equipment that requires periodic belt service or sheave changes. The 5V belt compatibility makes it appropriate for higher-horsepower drives where narrow-section belts are specified. Compatible belt cross-sections include 5V, A, and B profiles.

Compatibility

Designed as an OEM-style replacement or direct-fit sheave for single-groove V-belt drive systems using 5V, A, or B cross-section belts. Compatible with Type B QD bushings sold separately. Verify shaft diameter falls within the 5/8 inch to 2-1/4 inch bore range before ordering.

Installation Notes

Installation is performed by qualified millwrights or mechanical contractors following standard belt drive procedures. De-energize and lock out the drive system before beginning any sheave replacement or bushing work. The QD bushing must be sourced separately and matched to the actual shaft diameter. After mounting, set belt tension and alignment per the belt manufacturer specifications before returning the drive to service.
