Browning 1002708 Qd Bushed V-belt Sheave 3 Groove

Product Description

The BROWNING 1002708 is a three-groove, QD bushed V-belt sheave designed for power transmission applications in HVAC, industrial, and mechanical drive systems. It accepts a Q1-style quick-detach bushing, allowing fast installation and removal without special tooling. The outside diameter measures 12.75 inches, and the bore accepts shaft sizes from 0.75 inches up to 2.6875 inches, providing a wide range of shaft compatibility. Belt pitch A diameter is 12.0 inches and belt pitch B diameter is 12.4 inches. Weighing 25.8 pounds, this sheave is built for stationary drive applications and is installed by mechanical contractors, HVAC technicians, and industrial maintenance professionals.

This sheave is suited for belt-driven blower and fan assemblies commonly found in commercial air handling units, industrial ventilation systems, and heavy-duty HVAC equipment. The three-groove configuration supports multi-belt drive arrangements, which distribute load and reduce belt slippage under high-torque conditions. It is a direct-mount component that pairs with a separately sourced Q1 QD bushing to complete the drive assembly.

Compatibility

Designed as an OEM-style replacement or new-installation sheave for three-groove V-belt drive systems using Q1-style QD bushings. Compatible with standard A-section and B-section V-belts.

Installation Notes

Installation should be performed by a qualified mechanical contractor or HVAC technician familiar with belt-drive systems. De-energize and lock out the drive system before mounting or removing the sheave. A Q1 QD bushing must be sourced separately and installed per the bushing manufacturer torque sequence. Verify belt alignment and tension after installation before returning the system to service.
