Browning 1010560 3B60Q Qd Bushed V Belt Sheave 3 Groove

Product Description

The BROWNING 1010560 is a three-groove, QD (Quick Detachable) bushed V belt sheave designed for power transmission applications in industrial, commercial, and HVAC belt-drive systems. The sheave features a 6.35-inch outside diameter and accepts Q1-style QD bushings with a bore range of 3/4 inch to 2-11/16 inches, allowing it to fit a wide range of shaft sizes without requiring a dedicated bored-to-size hub. The A-series belt pitch diameter is 5.6 inches and the B-series belt pitch diameter is 6.0 inches. Weighing 10.8 pounds, this cast sheave is built for sustained duty in blower and fan drive assemblies. Licensed HVAC technicians, millwrights, and industrial mechanics are the primary installers.

This sheave is suited for three-belt drive configurations in belt-driven air handlers, centrifugal blowers, cooling tower fans, and general industrial equipment. The QD bushing system makes it particularly practical in retrofit and replacement scenarios where shaft diameter varies across installations. The 3/4-inch to 2-11/16-inch bore range covers the majority of fractional and integral horsepower motor shaft sizes encountered in light commercial and industrial environments.

Compatibility

Accepts Q1-style QD bushings with bore diameters from 3/4 inch to 2-11/16 inches. Compatible with standard A-series and B-series V belts. Designed as an OEM-style replacement or upgrade sheave for three-belt drive systems using Q1 QD bushings.

Installation Notes

Installation and removal should be performed by a qualified mechanic or licensed HVAC technician. Disconnect and lock out all power to the drive system before beginning work. Use the QD bushing fastener pattern to draw the bushing evenly into the sheave bore, and verify proper belt tension and sheave alignment with a straightedge or laser alignment tool before returning the drive to service. Follow applicable ANSI and OSHA machine guarding requirements for exposed belt drives.
