Browning 1033141 Two Groove V-belt Sheave 2.95in Od Cast Iron

Product Description

The BROWNING 1033141 is a finished bore, two-groove V-belt sheave machined from cast iron. It carries a 2.95-inch outside diameter and a 1-inch finished bore, making it ready to mount without additional machining. The belt pitch diameter measures 2.6 inches for standard B-section or A-section belts, with a 4L or A belt pitch diameter of 2.2 inches. This sheave is used in belt-drive power transmission systems on HVAC units, fans, blowers, and light industrial equipment. Installation is handled by HVAC technicians and mechanical contractors performing drive assembly or scheduled belt-and-sheave replacements.

This sheave fits drive configurations that call for a two-groove, finished bore pulley in the 2.95-inch OD range. It is commonly found on direct-drive and belt-drive blower assemblies in residential and light commercial HVAC systems, as well as on small motors in ventilation and process equipment. The finished bore eliminates field boring, reducing installation time on standard 1-inch motor or shaft outputs. The cast iron construction provides durability under continuous belt-load cycling.

Key Features

• Two-groove design supports dual V-belt drive configurations for increased torque capacity
• Finished 1-inch bore is ready to install on standard motor or driven-shaft outputs
• 2.95-inch outside diameter with a 2.6-inch belt pitch diameter for B or A cross-section belts
• Compatible with 4L and A belt profiles at a 2.2-inch pitch diameter
• Cast iron construction resists wear and deformation under sustained load
• Overall length through bore of 1-31/32 inches suits standard drive-frame spacing

Compatibility

Designed as an OEM-style replacement or new-installation sheave for belt-drive systems requiring a two-groove, 1-inch finished bore pulley with B-section or A-section V-belt compatibility.

Installation Notes

Installation is performed by licensed HVAC technicians or mechanical contractors. Disconnect and lock out power to the motor before removing or installing any sheave. Verify shaft diameter, keyway dimensions, and set-screw engagement before torquing fasteners. Align the sheave to the mating pulley using a straightedge or laser alignment tool to prevent premature belt wear and bearing failure.
