Browning 1002518 2TB90 Qd Bushed V Belt Sheave 2 Groove

Product Description

The BROWNING 1002518 is a 2TB90 two-groove, QD (Quick Detachable) bushed V belt sheave designed for industrial and commercial belt-drive applications. With a 9.35-inch outside diameter and compatibility with both A-section and B-section V belts, this sheave provides reliable power transmission in HVAC, pump, fan, and motor-drive systems. The Q1 bushing style allows for fast installation and removal without machining. Bore capacity ranges from 3/4 inch minimum to 2-11/16 inch maximum, covering a wide range of shaft sizes. Licensed HVAC and mechanical technicians install this type of component as part of belt-drive blower and fan assemblies. The unit weighs 15.8 pounds.

This sheave is suited for residential and light commercial HVAC air handlers, rooftop units, and ventilation fans where a two-groove V belt drive is specified. It also sees use in general industrial applications including pumps, compressors, and conveyor drives that require a QD bushed sheave in the 9-inch outside diameter class. Installers select this part when the system calls for A-pitch or B-pitch V belts and a quick-detach bushing hub for service convenience.

Key Features

• Bore range of 3/4 inch to 2-11/16 inch accommodates a wide variety of motor and driven-shaft diameters
• Compatible with both A-section (8.6-inch pitch diameter) and B-section (9.0-inch pitch diameter) V belts
• 9.35-inch outside diameter suits standard blower and fan drive configurations
• Robust cast construction rated for continuous-duty belt-drive service

Compatibility

Designed as an OEM-style replacement or upgrade sheave for two-groove QD bushed V belt drive systems using A-section or B-section V belts with a 9-inch outside diameter class sheave and a Q1 bushing hub.

Installation Notes

Installation and removal should be performed by a qualified mechanic or HVAC technician. Disconnect and lock out all power to the drive system before working on belt and sheave assemblies. The Q1 QD bushing must be matched and torqued to the manufacturer's bushing specification using appropriate hand tools before the drive is returned to service. Verify belt tension and sheave alignment with a straightedge or laser alignment tool after installation to prevent premature belt and bearing wear.
