Browning 3693942 Qd Bushed V-belt Sheave 2 Groove 6.08 in

Product Description

The BROWNING 3693942 is a two-groove, Quick Detachable (QD) bushed V-belt sheave designed for use with 5V, A, and B cross-section belts. With a 6.08-inch outside diameter and a bore range of 5/8 inch to 2-1/4 inches, this sheave accommodates a wide range of shaft sizes through a standard B-style QD bushing (sold separately). Cast from iron for durability under continuous drive loads, it is sized for light commercial and industrial fan, blower, and pump drive applications. HVAC and mechanical contractors routinely specify this sheave when building or servicing belt-drive air-handling systems.

This sheave fits belt-drive assemblies found in rooftop units, air-handling units, centrifugal blowers, and general mechanical equipment that require a two-groove, variable-speed or fixed-ratio V-belt drive. The broad bore range makes it adaptable to motor and driven-shaft diameters commonly encountered in commercial HVAC and light industrial installations. A licensed HVAC technician or millwright typically handles installation as part of a drive replacement or system commissioning job.

Key Features

• Two-groove design supports dual V-belt drives for higher torque transmission
• Compatible with 5V, A, and B cross-section V-belts for application flexibility
• B-style QD bushing mount allows fast installation and removal without special pullers
• Bore range of 5/8 inch to 2-1/4 inches fits a wide variety of shaft sizes
• Iron construction provides durability in continuous-duty belt-drive service
• 6.08-inch outside diameter enables common drive ratio configurations in blower and fan assemblies

Compatibility

Designed as an OEM-style replacement or new-installation sheave for two-groove V-belt drive systems using 5V, A, or B cross-section belts with a B-style QD bushing. Specific system compatibility depends on drive ratio requirements and shaft diameter at the installation site.

Installation Notes

Installation is typically performed by a licensed HVAC technician or millwright. Disconnect and lock out all power to the drive system before removing or mounting any sheave. The QD bushing must be sourced and installed separately per the bushing manufacturer torque sequence — do not overtighten fasteners beyond the bushing specification. After installation, verify belt tension and alignment with a straightedge or laser alignment tool before returning the unit to service.
