Browning 3695244 Qd Bushed V Belt Sheave 4 Groove

Product Description

The BROWNING 3695244 is a four-groove, quick-detachable (QD) bushed V belt sheave designed for industrial drive applications. It accepts 5V, A, and B belt profiles and mounts via a P1-style QD bushing, allowing fast, precise shaft installation and removal without special tooling. The outside diameter measures 4.68 inches, with a belt pitch diameter of 4.5 inches for 5V belts, 4.0 inches for A belts, and 4.4 inches for B belts. Bore capacity ranges from 0.5 inches minimum to 2.4375 inches maximum, covering a wide range of shaft sizes. Constructed from iron, it is suited for moderate-to-heavy duty belt drive systems in mechanical, HVAC, and industrial equipment.

This sheave is typically installed on fan, blower, and pump drives found in commercial HVAC air handlers, industrial ventilation systems, and general power transmission equipment. The four-groove configuration supports multi-belt drive setups where load sharing and reduced slippage are required. Licensed mechanical contractors, millwrights, and HVAC technicians routinely install this type of sheave when building or servicing belt drive assemblies that demand reliable torque transfer and consistent belt tension across multiple grooves.

Key Features

• Four grooves accommodate 5V, A, and B belt profiles in a single sheave
• P1-style QD bushing system enables tool-free bore sizing and quick shaft mounting
• Outside diameter of 4.68 inches with 4.5-inch 5V belt pitch diameter
• Bore range from 0.5 inches to 2.4375 inches suits a wide variety of shaft sizes
• Iron construction provides durability in continuous-duty drive applications
• Multi-belt groove design distributes load across belts to reduce wear

Compatibility

Compatible with 5V, A, and B designation V belts. Requires a P1-style QD bushing for installation, which is sold separately. Designed as an OEM-style replacement or new-installation sheave for multi-groove belt drive systems using these standard belt profiles.

Installation Notes

Installation should be performed by a qualified millwright or licensed mechanical technician familiar with belt drive systems. Disengage and lock out all power to the drive before removing or installing sheaves. The P1 QD bushing must be properly seated and fasteners torqued per the bushing manufacturer specifications before returning the drive to service. Verify belt tension and sheave alignment with a straightedge or laser alignment tool after installation to prevent premature belt and bearing wear.
