Browning 3695202 Qd Bushed V-belt Sheave 4 Groove 4.48 in Od

Product Description

The BROWNING 3695202 is a four-groove, Quick Detachable (QD) bushed V-belt sheave designed for use in industrial and commercial drive systems. It accepts 5V, A, and B cross-section belts and features a P1 bushing style for straightforward installation and removal without damaging the sheave or shaft. The outside diameter measures 4.48 inches, the belt pitch diameter for 5V belts is 4.3 inches, and the bore range spans 0.5 inches minimum to 2.4375 inches maximum. Cast iron construction provides the rigidity and wear resistance expected in belt-drive applications across HVAC, pump, fan, and blower systems. Licensed HVAC and mechanical contractors typically handle installation in commercial equipment.

This sheave is suited for multi-belt drive arrangements in commercial HVAC air handlers, industrial fans, centrifugal pumps, and similar rotating equipment that requires a compact, four-groove driven or driver pulley. The QD bushing interface allows the sheave to be mounted and demounted repeatedly without special tooling, making it practical for equipment with routine maintenance schedules. It is appropriate for both new drive installations and replacement of worn sheaves in existing belt-drive systems.

Compatibility

Designed as an OEM-style replacement or new-installation sheave for multi-belt drive systems using 5V, A, or B cross-section V-belts with a P1 QD bushing interface.

Installation Notes

Installation and removal should be performed by a qualified mechanic or licensed contractor with the drive system fully de-energized and locked out per OSHA LOTO procedures. The P1 QD bushing must be seated and torqued evenly using the threaded jacking screws provided with the bushing before the drive is returned to service. Verify belt tension and sheave alignment with a straightedge or laser alignment tool after installation. Do not operate the drive without all belt guards in place.
