Browning 1033091 Two Groove Sheave 1 in Bore Cast Iron

Product Description

The BROWNING 1033091 is a finished bore two groove sheave made from cast iron, designed for use with standard V-belt drive systems in HVAC, industrial, and mechanical power transmission applications. It features a 1 inch finished bore diameter and a 2.7 inch outer diameter, with a belt pitch diameter of 2.1 inches for Type 4L or A belts. The overall length through the bore measures 1-31/32 inches. At 1.45 pounds, this sheave is a compact, durable component suited for belt-drive configurations where reliable torque transfer is required.

This sheave is commonly installed in light- to medium-duty belt drive systems, including blower assemblies, fan drives, and auxiliary equipment found in commercial and residential HVAC units. The two-groove configuration allows dual-belt setups, increasing load capacity and redundancy in drive systems. Licensed HVAC technicians and mechanical contractors typically handle installations involving sheave replacement or drive system reconfigurations.

Installation Notes

Installation is typically performed by a licensed HVAC technician or qualified mechanic. Disconnect and lock out all power to the equipment before removing or installing any sheave or belt drive component. Verify shaft diameter and keyway dimensions match the finished bore before installation. Follow applicable ANSI and OSHA belt drive safety standards when tensioning belts after the sheave is seated.
