Browning 1043058 Qd Bushed V Belt Sheave 2 Groove 5.75 in

Product Description

The BROWNING 1043058 is a two-groove, Quick Detachable (QD) bushed V belt sheave designed for power transmission applications in HVAC, industrial, and mechanical drive systems. Built from cast iron with an H-style QD bushing mount, this sheave accepts A and B section V belts. The outside diameter measures 5.75 inches, with a belt pitch diameter of 5.0 inches for A section belts and 5.4 inches for B section belts. Bore diameter ranges from 0.375 inches minimum to 1.5 inches maximum, accommodating a wide range of shaft sizes. Licensed HVAC technicians and mechanical contractors typically install this component during blower drive assemblies or fan system builds.

This sheave is suited for residential and light commercial HVAC air handler blower drives, ventilation fan drives, and general mechanical power transmission setups where dual-belt redundancy or load sharing is required. The H-style QD bushing system allows quick installation and removal without specialized tooling, making it practical for service and maintenance work on belt-driven equipment. It is appropriate for applications that run standard A or B section V belts.

Compatibility

Designed as an OEM-style replacement or new-installation sheave compatible with A and B section V belt drive systems using an H-style QD bushing. Specific system compatibility depends on shaft size and belt section selection.

Installation Notes

Installation and removal should be performed by a qualified technician with the drive system fully de-energized and locked out per applicable OSHA lockout/tagout procedures. The H-style QD bushing must be matched to the shaft diameter before installation. Confirm belt section and sheave pitch diameter alignment across all drive components before tensioning. Do not run the drive system with missing or improperly torqued bushing hardware.
