Browning 1043157 2BK130H Qd Bushed V Belt Sheave 2 Groove

Product Description

The BROWNING 1043157 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 an H-style QD bushing and accommodates bore diameters from 3/8 inches to 1-1/2 inches, making it adaptable to a range of shaft sizes. The outside diameter measures 12.75 inches, with a belt pitch A diameter of 12.0 inches and a belt pitch B diameter of 12.4 inches. Constructed from iron, this sheave delivers the durability required in continuous-duty drive applications. Licensed HVAC mechanics, millwrights, and industrial technicians are the typical installers for this type of component.

This sheave is suited for residential and commercial HVAC equipment as well as general industrial belt drive systems where A or B section V belts are used. The QD bushing design allows for straightforward shaft mounting and removal without specialized machining. The two-groove configuration supports dual-belt drive setups, which are common in air handling units, blowers, fans, and pump drives where higher torque transmission or belt redundancy is required. Consult the drive design specifications for your application to confirm proper sheave-to-sheave alignment and belt selection.

Key Features

Compatibility

Designed for use with A and B section V belts in QD-bushed sheave drive systems requiring an H-style bushing. Suitable as an OEM-style or replacement sheave in belt drive assemblies across HVAC, fan, blower, and pump applications where a 12.75-inch outside diameter two-groove sheave is specified.

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 sheave components. Ensure the H-style QD bushing is properly seated and fasteners are torqued according to the bushing manufacturer specifications before returning the system to service. Verify sheave alignment with a straightedge or laser alignment tool to minimize belt wear and bearing load.
