Browning 1002948 Qd Bushed V Belt Sheave 3 Groove

Product Description

The BROWNING 1002948 is a three-groove, QD bushed V-belt sheave designed for industrial and commercial belt-drive systems. It accepts standard A-section and B-section V-belts, with an 18.0-inch A-section belt pitch diameter and an 18.4-inch B-section belt pitch diameter. The outside diameter measures 18.75 inches. The Q1 bushing style allows for a wide bore range, from 0.75 inches up to 2.6875 inches, making it adaptable to a variety of shaft sizes. HVAC equipment mechanics, millwrights, and industrial maintenance technicians are the typical installers for this class of sheave.

This sheave is suited for belt-drive applications found in commercial HVAC air handlers, industrial fans, blowers, compressors, and pump systems requiring a three-groove A or B section V-belt configuration. The QD bushing system simplifies installation and removal on the shaft without requiring specialized tooling beyond a standard hex wrench set. The wide bore range supports flexible shaft fitment across a broad range of rotating equipment platforms.

Key Features

• Compatible with both A-section (18.0-inch pitch diameter) and B-section (18.4-inch pitch diameter) V-belts
• Bore range of 0.75 inches to 2.6875 inches accommodates a wide variety of shaft diameters
• 18.75-inch outside diameter suited for low-speed, high-torque drive applications

Compatibility

Designed as a QD bushed replacement sheave for three-groove A and B section V-belt drive systems using Q1-style bushings. No specific model or system compatibility was provided in the product data.

Installation Notes

Installation and removal of QD bushed sheaves should be performed by a qualified millwright or mechanical technician with the drive system fully de-energized and locked out per applicable LOTO procedures. Ensure the shaft diameter falls within the 0.75-inch to 2.6875-inch bore range before selecting a Q1 bushing. Do not overtighten bushing bolts beyond the torque specifications listed on the bushing itself. Align sheave grooves carefully with a straightedge before tensioning belts to prevent premature belt and bearing wear.
