Bando AX66 Cogged V-belt Ax Section 68 in 1/2 in Width

Product Description

The BANDO AX66 is a classic cogged V-belt in the AX section profile, designed for power transmission in HVAC, refrigeration, and general industrial drive applications. It features a 68-inch outside length, a 1/2-inch belt width, and a 5/16-inch thickness. The cogged construction reduces bending resistance, which improves flexibility around smaller sheaves and helps lower operating temperatures. The rubber compound is formulated for heat and oil resistance, extending service life in demanding environments. Licensed HVAC technicians and mechanical contractors install this belt as a direct OEM-style replacement or new-installation drive component.

The AX66 is suited for residential and light commercial HVAC equipment, air handlers, condenser fan drives, and general belt-drive machinery that uses an AX-section sheave. The cogged profile allows it to run cooler and more efficiently than a standard wrapped belt of the same section. It meets ARPM standards, confirming dimensional and performance consistency with other ARPM-compliant AX-section belts. Technicians working on multi-belt drives should verify sheave groove angle and pitch diameter before installation to confirm proper engagement.

Key Features

• Classic cogged AX-section profile reduces bending resistance for improved efficiency on smaller sheaves
• 68-inch outside length with 66-inch internal length for precise drive sizing
• 1/2-inch width and 5/16-inch thickness match standard AX-section sheave geometry
• Heat-resistant and oil-resistant rubber compound for extended service life
• Meets ARPM dimensional and performance standards
• Black rubber construction, single belt per package

Compatibility

Designed as an OEM-style replacement or new-installation belt for equipment using an AX-section V-belt drive with a 68-inch outside length. Confirm sheave section and groove profile before installation.

Installation Notes

Installation should be performed by a qualified HVAC technician or mechanical contractor. De-energize all power to the equipment and lock out the disconnect before removing the existing belt or accessing drive components. Never pry a V-belt over a sheave flange — always release belt tension by adjusting the motor mount or idler before installation. After seating the new belt, set tension according to the equipment manufacturer's deflection specification and re-check tension after the first few hours of operation.
