Browning 1042613 BK100H Qd V-belt Sheave 1 Groove 9.75in

Product Description

The BROWNING 1042613 is a single-groove, Quick Detachable (QD) bushed V-belt sheave designed for use with A-section and B-section belts in industrial and HVAC drive applications. The sheave features a 9.75-inch outside diameter and accepts an H-style QD bushing, allowing bore sizes from 0.375 inches up to 1.5 inches to be accommodated without stocking multiple fixed-bore units. Constructed from cast iron, this sheave delivers the mass and surface hardness required for reliable belt-driven power transmission in blower, fan, and pump drive assemblies. Installation and removal are handled by licensed mechanics, millwrights, and HVAC technicians working on air handling and mechanical drive systems.

This sheave is suited for residential and commercial HVAC air handler fan drives, industrial blower assemblies, and general power transmission applications where A or B section V-belts are used. The QD bushing system simplifies shaft fitment across a range of shaft diameters, making it a practical choice for both new installations and replacement drive system work. The H bushing style is widely used in medium-duty fan and pump drive configurations.

Key Features

• Single-groove design sized for A-section and B-section V-belts
• 9.75-inch outside diameter with a 9.0-inch belt pitch diameter for A-section belts and 9.4-inch pitch diameter for B-section belts
• H-style QD bushing accommodates bore diameters from 0.375 inches to 1.5 inches
• Cast iron construction for durability and balanced mass in fan drive applications
• Quick Detachable bushing system speeds installation and removal without special tooling

Compatibility

Designed as an OEM-style replacement or new-installation sheave for single-groove A-section and B-section V-belt drives using H-style QD bushings in HVAC fan, blower, and industrial pump drive systems.

Installation Notes

Installation and removal should be performed by a qualified mechanic, millwright, or HVAC technician. Disconnect and lock out all power to the drive system before mounting or removing the sheave. The QD bushing must be ordered separately if not already on hand; confirm the H bushing bore size matches the driven shaft before assembly. Inspect belt tension and sheave alignment after installation per standard drive system practices.
