Browning 1042654 Qd V-belt Sheave 1 Groove 11.75 in Od

Product Description

The BROWNING 1042654 is a single-groove, QD bushed V-belt sheave designed for industrial power transmission applications. It accepts an H-style quick-disconnect bushing, allowing for fast installation and removal without the need for set screws bearing directly on the shaft. The outside diameter measures 11.75 inches, with a belt pitch A diameter of 11.0 inches and a belt pitch B diameter of 11.4 inches. Bore diameter range spans 0.375 inches to 1.5 inches, accommodating a wide variety of shaft sizes. Licensed HVAC and mechanical contractors, millwrights, and industrial maintenance technicians are the typical installers of this component in belt-drive systems.

This sheave is suited for single-groove V-belt drive systems found in HVAC air handling units, fans, blowers, pumps, and general industrial equipment. The H bushing style is a standard QD series size appropriate for mid-range shaft diameters and torque loads. It is used in both light commercial and industrial installations where reliable, serviceable belt drive power transmission is required. The 11.75-inch outside diameter makes it a common selection for fan and blower drive assemblies with moderate speed-ratio requirements.

Installation Notes

Installation and removal should be performed by a qualified millwright, HVAC technician, or industrial maintenance professional. Disconnect and lock out all power to the drive system before servicing the sheave or belt. The H-style QD bushing must be sourced separately and torqued per the bushing manufacturer specifications. Verify belt tension and sheave alignment after installation to prevent premature belt and bearing wear.
