Browning 1002633 Qd Bushed V Belt Sheave 2 Groove

Product Description

The BROWNING 1002633 is a two-groove, quick-detachable (QD) bushed V belt sheave designed for power transmission applications in HVAC, industrial, and mechanical drive systems. It accepts a Q1-style QD bushing and accommodates bore diameters ranging from 3/4 inches to 2-11/16 inches, making it adaptable to a wide range of shaft sizes. The outside diameter measures 11.35 inches, with a belt pitch A diameter of 10.6 inches and a belt pitch B diameter of 11.0 inches. Cast iron construction provides durability under continuous load. This sheave is installed by millwrights, HVAC mechanics, and maintenance technicians on belt-driven fan, blower, and pump assemblies.

This sheave is suited for residential and commercial HVAC systems, industrial blowers, and other belt-driven equipment where 5V, A, or B cross-section V belts are used. The two-groove configuration allows for dual-belt drive setups, distributing load and improving drive reliability. It is typically found on air handling units, centrifugal fans, and pump drives where shaft center distances and speed ratios require a sheave of this diameter range.

Key Features

• Two-groove design supports dual V belt configurations for improved load distribution
• Compatible with 5V, A, and B cross-section V belts
• QD bushing system with Q1 bushing style allows fast, secure shaft mounting and removal
• Bore range of 3/4 inches to 2-11/16 inches accommodates a wide variety of shaft sizes
• Cast iron construction for durability in continuous-duty drive applications
• 11.35-inch outside diameter suitable for common fan and blower drive configurations

Compatibility

Designed for use with 5V, A, and B cross-section V belts and requires a Q1-style QD bushing (sold separately). Suitable as an OEM-style replacement or upgrade sheave on belt-driven HVAC fan, blower, and pump assemblies using compatible shaft diameters.

Installation Notes

Installation should be performed by a qualified mechanic or HVAC technician. Disconnect and lock out all power to the drive system before mounting or removing the sheave. The QD bushing must be sourced and installed separately according to the bushing manufacturer's torque and assembly procedures. Verify belt tension and sheave alignment with a straightedge or laser alignment tool after installation to prevent premature belt and bearing wear.
