Browning 3693892 Qd Bushed V-belt Sheave 2 Groove 5.08in

Product Description

The BROWNING 3693892 is a two-groove, QD bushed V-belt sheave designed for use with 5V, A, and B belt profiles. It features a 5.08-inch outside diameter and accepts bore sizes ranging from 5/8 inch to 2-1/4 inches, accommodating standard B-style QD bushings for a secure, concentric fit. Cast from iron for rigidity and long service life, this sheave suits HVAC blower assemblies, fans, pumps, and other belt-driven mechanical systems where precise power transmission is required. Belt pitch diameters are 4.9 inches for 5V belts, 4.8 inches for B belts, and 4.4 inches for A belts. HVAC technicians and mechanical contractors select this sheave when replacing or upgrading drive components on air-handling units and similar equipment.

This sheave is used in belt-driven systems found in light commercial and industrial HVAC applications, including rooftop units, air handlers, and ventilation fans. The QD bushing system allows for straightforward installation and removal without special pullers, making it practical for service technicians working on fan decks and blower sections. It is suited for any application requiring a two-groove sheave in the 5V, A, or B belt class within its bore and diameter range.

Key Features

• Two-groove design accepts 5V, A, and B profile V-belts
• Outside diameter of 5.08 inches with a 5V belt pitch diameter of 4.9 inches
• Bore range from 5/8 inch to 2-1/4 inches fits a wide range of shaft sizes
• B-style QD bushing mount for tool-accessible installation and removal
• Iron construction provides durability and dimensional stability under load

Compatibility

Compatible with 5V, A, and B profile V-belts. Requires a B-style QD bushing, sold separately, to complete the assembly. Designed as an OEM-style replacement or upgrade sheave for belt-driven HVAC blowers, fans, and pump drives within the specified bore and belt profile range.

Installation Notes

Installation should be performed by a qualified HVAC technician or mechanical contractor. Disconnect and lock out all power to the drive system before removing or installing sheaves. Ensure the correct B-style QD bushing is selected for the shaft diameter before assembly, and align the sheave parallel to the mating sheave to prevent premature belt wear. Belt tension should be verified with a tension gauge after installation and rechecked after initial run-in.
