Browning 1043033 2BK55H Qd V-belt Sheave 2 Groove 5.25 in

Product Description

The BROWNING 1043033 is a two-groove, QD (Quick Detach) bushed V-belt sheave designed for power transmission applications in HVAC, industrial, and mechanical drive systems. Manufactured from iron, this sheave accepts an H-style QD bushing and accommodates bore diameters from 3/8 inch up to 1.5 inches, making it adaptable across a wide range of shaft sizes. The outside diameter measures 5.25 inches, with a belt pitch A diameter of 4.5 inches and a belt pitch B diameter of 4.9 inches. It is compatible with both A and B cross-section V-belts. Licensed HVAC mechanics, millwrights, and mechanical contractors typically handle installation of components like this in belt-driven blower and fan assemblies.

This sheave is suited for residential and commercial belt-driven systems including supply and return air fan assemblies, cooling tower drives, and other rotating equipment requiring a two-groove V-belt arrangement. The QD bushing design allows the sheave to be installed and removed without specialized tooling, reducing labor time during scheduled maintenance or component replacement. It is well-suited for retrofit and replacement scenarios where the existing drive arrangement calls for an H-bushing style sheave with a 5.25-inch outside diameter.

Compatibility

Designed as an OEM-style replacement or direct-fit sheave for belt-driven fan and blower assemblies requiring a 2-groove, H-bushing QD sheave with a 5.25-inch outside diameter and compatibility with A and B cross-section V-belts.

Installation Notes

Installation should be performed by a qualified mechanic or HVAC technician. Disconnect and lock out all power to the drive system before removing or installing any sheave or bushing. Inspect the mating QD H-style bushing and shaft for wear or damage before assembly. Confirm proper belt tension and sheave alignment after installation to prevent premature belt and bearing wear.
