Browning 1001445 3 Groove Qd Bushed V Belt Sheave

Product Description

The BROWNING 1001445 is a three-groove, QD bushed V belt sheave designed for power transmission applications in HVAC, industrial, and mechanical systems. It features a 4.55-inch outside diameter and accepts bore diameters from 0.5 inches to 1.75 inches, making it adaptable to a range of shaft sizes using a standard P1 bushing style. The A belt pitch diameter is 3.8 inches and the B belt pitch diameter is 4.2 inches. At 5.2 pounds, this cast sheave is a direct-mount, field-adjustable component installed by HVAC technicians and millwrights during belt drive system service or replacement.

This sheave is suited for use in belt-driven air handling units, blowers, fans, and other rotary equipment that rely on V belt power transmission. The QD bushing design allows for straightforward installation and removal without specialized pullers in most cases, reducing downtime during scheduled maintenance or emergency service. It is appropriate for both commercial and light industrial applications where three-groove A or B section belt configurations are required.

Installation Notes

Installation should be performed by a qualified HVAC technician or millwright. Disconnect and lock out all power to the drive system before removing or installing any sheave or bushing. Ensure the mating shaft diameter falls within the 0.5 to 1.75-inch bore range before ordering the appropriate P1 QD bushing. After installation, verify belt tension and sheave alignment per the drive manufacturer's specifications before returning the system to service.
