Browning 1043165 Qd V Belt Sheave 2 Groove 13.75in Od

Product Description

The BROWNING 1043165 is a two-groove, QD bushed V belt sheave designed for industrial and commercial power transmission applications. It accepts an H-style Quick Detachable bushing and accommodates bore diameters from 0.375 inches to 1.5 inches, making it adaptable to a range of shaft sizes without requiring a dedicated fixed-bore configuration. The sheave has an outside diameter of 13.75 inches and a Belt Pitch A diameter of 13.0 inches. Weighing 15.3 pounds, this is a robust cast component intended for installation by millwrights, HVAC mechanics, and industrial maintenance technicians on belt-driven equipment such as fans, blowers, and pumps.

This sheave is suited for two-belt A-section or B-section V belt drive systems in both residential and commercial mechanical installations. Typical applications include air handling unit fan drives, cooling tower drives, and general-purpose industrial blower assemblies where reliable, adjustable power transmission is required. The QD bushing system allows fast mounting and removal during scheduled maintenance without special tooling beyond standard hex keys and a torque wrench.

Key Features

• Two-groove configuration supports dual V belt drive setups for increased power capacity
• QD H-style bushing mount allows quick installation and removal on shafts from 0.375 to 1.5 inches
• 13.75-inch outside diameter with 13.0-inch Belt Pitch A diameter for accurate belt speed calculations
• Belt Pitch B diameter of 13.4 inches supports B-section belt compatibility
• Weighs 15.3 pounds — robust construction suitable for continuous-duty drives

Compatibility

Designed for use with H-style QD bushings and A-section or B-section V belts. Compatible bore range of 0.375 to 1.5 inches covers common shaft sizes found in commercial fan and blower drive assemblies. Specific bushing must be ordered separately to match the required shaft diameter.

Installation Notes

Installation and removal should be performed by a qualified millwright or mechanical technician. De-energize and lock out the drive system fully before beginning any sheave work in accordance with OSHA lockout/tagout procedures. Seat the QD bushing to the sheave flange before tightening fasteners evenly in a cross pattern to draw the bushing uniformly. Verify belt alignment and tension with a straightedge and tension gauge after installation before returning the drive to service.
