Browning 3694106 Qd V Belt Sheave 2 Groove 16.28 in

Product Description

The BROWNING 3694106 is a two-groove, QD bushed V belt sheave designed for power transmission applications in HVAC, industrial, and mechanical systems. It accepts 5V, A, and B section belts and fits bore diameters from 5/8 inch up to 2-1/4 inch using a B-style QD bushing. The outside diameter measures 16.28 inches, with a 5V belt pitch diameter of 16.1 inches and a B-section belt pitch diameter of 16.0 inches. Cast iron construction provides durability in demanding drive configurations. This sheave is installed by HVAC technicians and mechanical contractors performing blower, fan, or pump drive replacements and setups.

This sheave is well suited for residential and commercial HVAC air handler drives, industrial fan drives, and pump systems where a two-groove 5V or B-section belt arrangement is required. The QD bushing design allows for straightforward bore sizing in the field by selecting the appropriate B-style bushing to match shaft diameter. It is commonly used in rooftop units, belt-drive air handlers, and industrial blower assemblies that require consistent, high-torque power transmission.

Key Features

• Two-groove design accommodates parallel belt drive configurations for increased torque capacity
• Compatible with 5V, A, and B section V belts for application flexibility
• QD bushing system with B-style bushing accepts bore diameters from 5/8 inch to 2-1/4 inch
• 16.28 inch outside diameter suits larger blower and fan drive setups
• Cast iron construction resists wear under continuous load
• UNSPSC Code 31171804 for procurement and inventory classification

Compatibility

Designed as an OEM-style replacement or new-installation sheave for belt-drive systems using 5V, A, or B section V belts with a B-style QD bushing. Compatible bore range of 5/8 inch to 2-1/4 inch covers a wide range of shaft sizes in commercial and industrial drive applications.

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 any sheave or bushing components. The QD bushing must be selected separately to match the specific shaft diameter within the stated bore range. Verify belt alignment and belt tension with a tension gauge after installation to prevent premature belt or bearing wear.
