Browning 3694213 3-groove Qd V-belt Sheave 5.88in Od

Product Description

The BROWNING 3694213 is a three-groove, Quick Detachable (QD) bushed V-belt sheave designed for industrial and commercial HVAC, fan, blower, and pump drive applications. The sheave features a 5.88-inch outside diameter and accepts bore diameters from 5/8 inch up to 2-1/4 inches via a B-style QD bushing, which is sold separately. At 7.85 pounds, the unit is built for reliable power transmission across multi-belt drive configurations. Belt pitch diameters are 5.2 inches for A-section belts, 5.6 inches for B-section belts, and 5.7 inches for 5V-section belts.

This sheave is suited for three-belt drive systems found in commercial air handling units, rooftop HVAC equipment, industrial blowers, and centrifugal fans. The QD bushing system allows for straightforward installation and removal without special pullers, making it a practical choice for maintenance-intensive environments. It is typically installed by HVAC mechanics and industrial millwrights servicing belt-driven equipment where precise sheave alignment and belt pitch matching are required.

• QD B-style bushing interface allows tool-free bore adjustment from 5/8 inch to 2-1/4 inches
• Compatible with A-section, B-section, and 5V-section V-belts
• 5.88-inch outside diameter suits common commercial HVAC and blower drive setups
• Robust 7.85-pound construction for sustained power transmission duty

Compatibility

Designed as an OEM-style replacement or upgrade sheave for three-groove V-belt drive systems using B-style QD bushings and A, B, or 5V cross-section belts.

Installation Notes

Installation should be performed by a qualified HVAC mechanic or industrial millwright. De-energize the drive system and lock out or tag out all power sources before removing or installing any sheave. Verify bushing bore size and belt section compatibility before mounting, and check sheave alignment with a straightedge or laser alignment tool after installation to prevent premature belt wear. Follow applicable ANSI and OSHA machine-guarding requirements when reassembling belt drive covers.
