Browning 1042969 Qd Bushed V Belt Sheave 2 Groove

Product Description

The BROWNING 1042969 is a two-groove, quick-detachable (QD) bushed V belt sheave designed for power transmission applications in HVAC, industrial, and mechanical drive systems. It accepts A and B cross-section V belts, with a belt pitch diameter of 2.8 inches for A-section and 3.2 inches for B-section belts. The outside diameter measures 3.55 inches, and the sheave accommodates an H-style QD bushing with a bore range of 3/8 inch minimum to 1-1/2 inch maximum. Cast iron construction provides durability under continuous belt-drive load. Mechanical contractors and HVAC technicians install this sheave on blower, fan, and pump drive systems requiring precise belt alignment and easy shaft removal.

This sheave is suited for residential and light commercial HVAC air handlers, rooftop units, and belt-driven fan assemblies where A or B section V belts are used. The H bushing style allows quick installation and removal without damaging the shaft. With two grooves, it can drive dual-belt configurations common on larger blower assemblies, improving load distribution and reducing belt wear in high-cycle applications.

Compatibility

Designed as an OEM-style replacement or direct-install sheave for belt-driven blower and fan systems using A or B cross-section V belts with an H-style QD bushing mount.

Installation Notes

Installation should be performed by a qualified mechanical or HVAC technician. Disconnect and lock out all power to the drive system before removing or installing any sheave or bushing. Ensure the QD bushing bore matches the shaft diameter before tightening fasteners, and verify belt alignment and tension after installation per belt manufacturer guidelines. Refer to applicable mechanical and electrical codes for lockout/tagout procedures.
