Browning 1028000 Single Groove Sheave 3.15in Od 5/8in Bore

Product Description

The BROWNING 1028000 is a finished bore single groove sheave designed for V-belt drive systems in HVAC, industrial, and mechanical power transmission applications. It features a 5/8 inch bore diameter and a 3.15 inch outer diameter, with a pitch diameter of 2.4 inches for 4L or A-type belts. The sheave body is cast iron, providing durable, wear-resistant performance in demanding belt drive environments. The through-bore length is 1-1/16 inches, and the groove width is 13/16 inches. Licensed HVAC technicians and mechanical contractors use this sheave as a direct replacement or new installation component on belt-driven blower and fan assemblies.

This single groove sheave suits residential and light commercial belt-driven systems, including air handling units, fan coil units, and blower assemblies that use 4L or A-section V-belts. The finished bore is ready to install without additional machining, making it straightforward for field replacement on standard 5/8 inch shafts. It is appropriate for use wherever a compact, single-groove cast iron sheave is required in a V-belt drive configuration.

Installation Notes

Installation is typically performed by licensed HVAC technicians or mechanical contractors. Disconnect and lock out all power to the belt drive system before removing or installing any sheave. Verify shaft diameter and belt section type before installation, and inspect the mating belt and bushing for wear. Follow applicable local mechanical codes and the equipment manufacturer guidelines for belt tensioning and alignment.
