Eaton 6-34-2 V-belt Drive Sheave Nema 2 Ax Bx Cx

Product Description

The EATON 6-34-2 is a NEMA 2 adjustable V-belt drive sheave designed to accommodate AX, BX, and CX belt cross-sections. This sheave functions as the driven or driving pulley in a belt-and-sheave power transmission assembly, transferring rotational force between motor and load shafts in HVAC air handlers, blowers, and related belt-driven mechanical equipment. At 0.25 pounds, it is a lightweight yet durable component suited for use wherever NEMA 2 sheave sizing applies. Licensed HVAC technicians and millwrights are the primary installers of this type of drive component.

This sheave is appropriate for residential and light commercial HVAC applications where adjustable V-belt drives are used, including belt-driven supply fans, blower assemblies, and other rotating equipment matched to AX, BX, or CX belt profiles. It is selected when the drive system requires a NEMA 2 sheave position and the belt cross-section falls within the AX, BX, or CX range. Consult the drive system engineering data to confirm correct pitch diameter and speed ratio before installation.

Key Features

• NEMA 2 sheave size classification for standardized drive selection
• Compatible with AX, BX, and CX V-belt cross-sections
• Lightweight construction at 0.25 pounds
• Designed for belt-driven HVAC and mechanical power transmission assemblies

Compatibility

Designed for use in belt-drive systems requiring a NEMA 2 sheave with AX, BX, or CX V-belt cross-sections. Verify pitch diameter, bore size, and belt profile against the driven equipment specifications before installation.

Installation Notes

Installation should be performed by a qualified HVAC technician or millwright. Disconnect and lock out all electrical power to the equipment before removing or installing any sheave or belt component. Confirm shaft bore fit and set-screw engagement before tensioning the belt, and follow the equipment manufacturer guidelines for proper belt tension and sheave alignment to prevent premature wear.
