Browning 3694247 Qd Bushed V Belt Sheave 3 Groove

Product Description

The BROWNING 3694247 is a three-groove, Quick Detachable (QD) bushed V-belt sheave designed for industrial and mechanical drive applications. It accepts 5V, A, and B section belts and features a cast iron construction for durability under continuous load. The outside diameter measures 6.48 inches, with a belt pitch diameter of 6.3 inches on the 5V profile. Bore range runs from 0.625 inches minimum to 2.25 inches maximum, accommodating a QD B-style bushing. This sheave is installed by millwrights, HVAC mechanics, and industrial maintenance technicians in belt-driven equipment such as fans, blowers, and pumps.

This sheave fits belt-driven systems where 5V, A, or B section V-belts are used. Common applications include air handling units, centrifugal blowers, industrial fans, and pump drives in both commercial HVAC and general industrial settings. The QD bushing design allows the sheave to be mounted and removed without special pullers, making it well suited for maintenance-heavy installations where downtime is a concern. The three-groove configuration supports multi-belt drives that require higher torque capacity than a single-belt arrangement.

Installation Notes

Installation should be performed by a qualified millwright or mechanical technician. De-energize and lock out the drive system before removing or installing the sheave. Ensure the mating QD B-style bushing is the correct size for the shaft diameter before assembly. Belt tension should be set according to belt manufacturer specifications after alignment is confirmed; do not over-tension, as this can cause premature bearing failure.
