Browning 1043181 Qd V Belt Sheave 2 Groove 18.75in Od

Product Description

The BROWNING 1043181 is a two-groove, QD bushed V belt sheave designed for industrial belt drive systems. It accepts an H-style quick-detach bushing, allowing straightforward installation and removal without specialized tooling. The sheave measures 18.75 inches in outside diameter with an A-section belt pitch diameter of 18.0 inches and a B-section belt pitch diameter of 18.4 inches. Bore diameter ranges from 3/8 inch minimum to 1-1/2 inch maximum, making it compatible with a wide range of shaft sizes. Mechanical contractors, millwrights, and HVAC technicians install this sheave in fan, blower, and pump drive applications where dual V belt configurations are required.

This sheave is suited for residential and commercial HVAC air handling units, industrial blowers, and pump drive assemblies using A or B section V belts. The two-groove design supports parallel belt operation, distributing load across both belts for improved drive efficiency and reduced belt wear. The QD bushing mount allows fast shaft alignment adjustment, which is common in retrofit and replacement scenarios on rooftop units, air handlers, and centrifugal blowers.

Installation Notes

Installation should be performed by a qualified millwright, mechanical contractor, or HVAC technician. Disconnect and lock out all power to the drive system before handling the sheave or bushing. Verify shaft diameter falls within the 3/8 inch to 1-1/2 inch bore range before selecting a bushing. After mounting, check belt tension and sheave alignment with a straightedge or laser alignment tool before returning the drive to service.
