Bando AX78 Cogged V-belt Ax Section 80 in 1/2 in Width

Product Description

The BANDO AX78 is a classic cogged V-belt in the AX section, designed for power transmission applications across HVAC, refrigeration, agricultural, and light industrial equipment. It measures 80 inches outside length with a 1/2 inch width and 5/16 inch thickness. The cogged construction reduces bending resistance, which increases flexibility and allows the belt to run cooler on smaller-diameter sheaves. Built from rubber with heat-resistant and oil-resistant properties, the AX78 is suited for demanding drive systems where a standard smooth-back belt would wear prematurely or slip under load. Licensed technicians and equipment service professionals install this belt as a direct replacement in belt-driven systems.

The AX78 fits belt-driven equipment that calls for an AX-section cogged V-belt with an 80 inch outside length. Typical applications include condenser fan drives, blower assemblies, compressor drives, and general-purpose machinery drives in both residential and light commercial settings. The cogged profile is especially effective on variable-speed drives and drives using smaller sheave diameters where flex fatigue is a concern. Meets ARPM standards, confirming dimensional and performance conformance with industry specifications for AX-section belts.

Key Features

• Classic cogged AX-section profile reduces bending stress and heat buildup on smaller sheaves
• 80 inch outside length with 78 inch internal length and 79.3 inch pitch length
• 1/2 inch width and 5/16 inch thickness for standard AX-section sheave fit
• Heat-resistant and oil-resistant rubber construction extends service life in demanding environments
• Meets ARPM dimensional and performance standards
• Black rubber construction; single-belt packaging

Compatibility

Designed as a direct replacement for equipment requiring an AX-section cogged V-belt with an 80 inch outside length. Confirm sheave groove profile and center-to-center distance against equipment specifications before installation.

Installation Notes

Belt replacement should be performed by a qualified technician. Disconnect and lock out all power to the drive system before removing the old belt or installing the new one. Do not force the belt over sheave flanges with a pry bar, as this can damage the cord structure; always release drive tension first by adjusting the motor mount or idler. After installation, set belt tension per the equipment manufacturer specifications and re-check tension after the first hour of operation.
