Browning 1026152 Single Groove Sheave 0.75 in Bore Cast Iron

Product Description

The BROWNING 1026152 is a finished bore single groove sheave designed for V-belt drive applications in HVAC, industrial, and mechanical systems. Cast iron construction gives this sheave the rigidity and wear resistance needed for continuous-duty belt drive service. The bore diameter is 0.75 inches with an overall outside diameter of 2.8 inches and a groove width of 21/32 inches. The overall length through bore is 15/16 inches. Licensed HVAC technicians and mechanical contractors use this sheave type when setting up or replacing blower drive assemblies, fan drives, and similar belt-driven equipment.

This sheave is suited for residential and light commercial belt drive installations where a single groove V-belt configuration is required. It accepts 4L or A-type belts with a pitch diameter of 2.6 inches, and 3L-type belts with a pitch diameter of 2.26 inches. Typical applications include air handler blower assemblies, evaporative cooler fan drives, exhaust fan assemblies, and general mechanical drive systems requiring a small-diameter single groove sheave with a finished 0.75-inch bore.

Installation Notes

Installation is typically performed by licensed HVAC technicians or qualified mechanical contractors. De-energize the unit and lock out the power supply before removing or installing any sheave or belt. Verify belt alignment and tension after installation to prevent premature belt and bearing wear. Refer to applicable mechanical and electrical codes for lockout/tagout procedures before servicing belt drive assemblies.
