Browning 1042985 Qd Bushed V Belt Sheave 2 Groove

Product Description

The BROWNING 1042985 is a two-groove, quick-detachable (QD) bushed V-belt sheave designed for power transmission applications in HVAC, industrial, and commercial equipment. It accepts A and B series V-belts and features an H-style QD bushing interface for fast, precise shaft mounting without the need for machining. The outside diameter measures 3.95 inches, with a belt pitch A diameter of 3.2 inches and a belt pitch B diameter of 3.6 inches. Bore range spans 3/8 inch minimum to 1-1/2 inch maximum. Cast iron construction provides durability under continuous belt-drive load. This sheave is installed by HVAC mechanics, millwrights, and mechanical contractors on belt-driven fans, blowers, and pumps.

This sheave is suited for residential and commercial HVAC fan assemblies, air handling units, exhaust systems, and light industrial belt-drive setups where A or B series belts are specified. The two-groove design supports dual-belt configurations common in blower and fan applications that require balanced load distribution. The H-style QD bushing allows for straightforward bore sizing and alignment across a wide range of shaft diameters within the listed bore range.

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 belt components. The QD bushing must be properly seated and fastener torque applied per the bushing manufacturer specifications using appropriate hand tools. Verify belt tension and sheave alignment with a straightedge or laser alignment tool after installation to prevent premature belt and bearing wear.
