Browning 1043173 2BK160H Qd Bushed V-belt Sheave 2 Groove

Product Description

The BROWNING 1043173, model 2BK160H, is a two-groove, quick-detach (QD) bushed V-belt sheave designed for industrial and commercial power transmission applications. It accepts an H-style QD bushing and supports bore diameters from 0.375 inches up to 1.5 inches, making it adaptable across a range of shaft sizes. With a 15.75-inch outside diameter and an A-section belt pitch diameter of 15.0 inches, this sheave is built for systems that require a large-diameter drive wheel in a dual-groove configuration. At 20.1 pounds, it is suited for fixed-mount drives on fan, blower, pump, and compressor assemblies where belt alignment and load sharing across two grooves are critical.

This sheave is commonly installed in HVAC air handler and rooftop unit fan drives, industrial blower systems, and pump skid assemblies. The H-style QD bushing interface allows the sheave to be mounted and removed without specialized pullers, reducing downtime during maintenance. Dual-groove construction enables two matched V-belts to share the drive load, which is standard practice in higher-horsepower or vibration-sensitive applications. Installation is performed by licensed HVAC technicians, millwrights, or mechanical contractors as part of belt-drive system builds or replacements.

Key Features

• Two-groove design distributes load across matched V-belt pairs for improved drive reliability
• H-style QD bushing interface accepts bore diameters from 0.375 inches to 1.5 inches
• 15.75-inch outside diameter suits large-ratio or low-speed-output drive configurations
• A-section belt pitch diameter of 15.0 inches and B-section pitch diameter of 15.4 inches
• QD bushing system allows tool-assisted mounting and removal without a dedicated puller
• Weighs 20.1 pounds — appropriate for fixed, bracket-mounted or base-plate drive assemblies

Compatibility

Designed as an OEM-style replacement or new-installation sheave for two-groove V-belt drive systems using H-style QD bushings and A- or B-section V-belts on shafts from 0.375 inches to 1.5 inches in diameter.

Installation Notes

De-energize and lock out the drive system before removing or installing the sheave. Ensure the H-style QD bushing is sourced separately and matched to the target shaft diameter before assembly. Align the sheave faces to within manufacturer-recommended tolerances using a straightedge or laser alignment tool to prevent premature belt and bearing wear. Belt tension should be set per the belt manufacturer specification for A- or B-section belts after installation.
