Browning 1025923 Single Groove Sheave 2.2 in Od 5/8 in Bore

Product Description

The BROWNING 1025923 is a finished bore single groove sheave designed for V-belt drive systems in light-duty power transmission applications. With a 2.2-inch outer diameter and a 5/8-inch finished bore, this sheave is ready to mount without additional machining. Cast iron construction provides durability in industrial and mechanical environments. The 21/32-inch face width and 2.4-inch belt pitch diameter make this sheave compatible with standard A-section and 4L V-belts. It weighs 0.5 pounds and is suited for installation by HVAC technicians, millwrights, and mechanical service professionals.

This sheave is used in belt drive assemblies where a compact single groove pulley is required. Typical applications include small fan drives, blower assemblies, and auxiliary equipment drives in residential and light commercial HVAC systems. The finished bore eliminates field boring, reducing installation time on service calls or equipment assembly. The pitch diameter of 2.0 inches for A-section and 4L belts, and 1.66 inches for 3L belts, allows selection of the correct belt for the drive ratio required.
