Browning 1025824 Single Groove Sheave 0.5 in Bore 2 in Od

Product Description

The BROWNING 1025824 is a finished bore single groove sheave designed for V-belt drive applications in HVAC, industrial, and mechanical systems. Cast iron construction provides durability under continuous load. The sheave features a 0.5 inch bore diameter, a 2 inch outer diameter, and a groove width of 21/32 inches. The overall length through bore measures 15/16 inches. Licensed HVAC technicians and mechanical contractors typically install this component when servicing blower assemblies, fan drives, and belt-driven equipment requiring a single groove pulley configuration.

This sheave is suited for residential and light commercial HVAC blower drives, exhaust fans, and general-purpose belt drive assemblies. It accepts standard B-section and A-section V-belts with a pitch diameter of 1.8 inches, as well as 3L-section belts with a pitch diameter of 1.46 inches. The finished bore allows direct installation onto a matching shaft without additional machining. Applications include air handler blower pulleys, condenser fan drives, and other single-belt mechanical drive setups where a compact, cast iron sheave is specified.

Installation Notes

Installation should be performed by a qualified HVAC technician or mechanical tradesperson. De-energize the unit and lock out the power supply before removing or installing any belt drive components. Ensure the shaft diameter matches the 0.5 inch finished bore and that the mating belt type matches the groove profile before mounting. Verify belt tension and sheave alignment after installation to prevent premature belt and bearing wear.
