Browning 1033216 Two Groove Sheave 3.15in Od Cast Iron

Product Description

The BROWNING 1033216 is a finished bore, two groove sheave designed for V-belt drive applications in mechanical and HVAC systems. Cast from iron, this sheave features a 3.15 inch outer diameter and a 1-1/8 inch finished bore, ready for direct shaft installation without additional boring. With a belt pitch diameter of 2.8 inches and a 4L/A belt pitch diameter of 2.4 inches, the 1033216 is suited for light-to-medium duty belt drive systems. It is installed by millwrights, HVAC mechanics, and equipment technicians in situations where a reliable, pre-finished sheave is required to reduce setup time on a drive replacement or new build.

This sheave is intended for use in belt-driven mechanical systems where standard V-belts of the 4L or A cross-section are specified. Typical applications include fan drives, blower assemblies, and auxiliary equipment drives found in commercial and residential HVAC equipment, light industrial machinery, and similar rotating equipment. The finished bore and two-groove configuration make it a practical choice for direct replacement of worn or damaged sheaves on existing drive systems without machining.

Key Features

• Two groove configuration supports dual V-belt drives for increased torque capacity
• Finished 1-1/8 inch bore is ready for shaft installation without additional machining
• 3.15 inch outer diameter with a 2.8 inch belt pitch diameter for accurate belt alignment
• Compatible with 4L and A cross-section V-belts with a 2.4 inch pitch diameter for that belt type
• Cast iron construction provides durability in belt drive environments
• Overall length through bore of 1-31/32 inches for compact axial footprint

Compatibility

Designed as an OEM-style replacement sheave for V-belt drive assemblies using 4L or A cross-section belts in fan, blower, and general mechanical drive applications.

Installation Notes

Installation should be performed by a qualified mechanic or HVAC technician. Disconnect and lock out all power to the drive system before removing or installing sheaves. Ensure the bore is clean and the shaft is within tolerance before pressing or sliding the sheave into position, and secure with the appropriate keyway and set screw hardware. Check belt tension and sheave alignment with a straightedge or laser alignment tool after installation before returning the system to service.
