Browning 1002526 Qd Bushed V Belt Sheave 3 Groove

Product Description

The BROWNING 1002526 is a three-groove, quick-detachable (QD) bushed V-belt sheave designed for power transmission applications in HVAC, industrial, and mechanical drive systems. It accepts standard A-section and B-section V-belts and features a Q1 bushing style for straightforward installation and removal without damaging the sheave or shaft. The outside diameter measures 9.35 inches, with a belt pitch diameter of 8.6 inches for A-section belts and 9.0 inches for B-section belts. Bore range runs from 3/4 inch minimum to 2-11/16 inch maximum, covering a wide range of shaft sizes. This sheave weighs 17.8 pounds and is suited for multi-belt drive configurations requiring reliable torque transfer.

This sheave is used in commercial and industrial mechanical drive systems where multi-groove V-belt setups are required. Typical applications include blower drives, fan drives, pump drives, and compressor drives found in HVAC equipment and industrial machinery. The three-groove configuration allows simultaneous use of three V-belts, increasing the load capacity and torque transfer capability of the drive assembly. Licensed mechanical contractors, HVAC technicians, and industrial maintenance professionals are the primary installers of this component.
