Bando AX77 Cogged V-belt Ax Section 79 in 1/2 in

Product Description

The BANDO AX77 is a classic cogged V-belt designed for power transmission applications across HVAC, agricultural, industrial, and light commercial equipment. The cogged construction reduces bending resistance, which improves flexibility and heat dissipation compared to a standard wrapped belt. This belt measures 79 inches outside length with a 1/2-inch width and 5/16-inch thickness. Built from rubber with heat-resistant and oil-resistant properties, the AX77 carries an ARPM standard rating, making it a reliable OEM-style replacement or upgrade for a wide range of belt-driven systems. Installation is typically handled by HVAC technicians, equipment mechanics, or maintenance professionals.

The AX77 fits AX-section belt drive applications including blower assemblies, fan drives, compressor drives, and general-purpose power transmission setups found in residential and light commercial HVAC equipment as well as industrial machinery. The cogged profile makes it well suited for smaller-diameter sheaves where a standard belt would experience excessive heat buildup or slippage. The black rubber construction holds up under the thermal cycling and minor oil exposure common in mechanical equipment rooms and rooftop units.

Key Features

• AX section cogged design reduces bending resistance for improved efficiency on small-diameter sheaves
• 79 inches outside length with 77 inches internal length for precise fitment
• 1/2-inch width and 5/16-inch thickness match standard AX-section drive requirements
• Heat-resistant and oil-resistant rubber construction extends service life in demanding environments
• Meets ARPM standards for V-belt dimensional and performance consistency
• Classic cogged style compatible with standard AX-section sheaves and pulleys

Compatibility

Designed as an OEM-style replacement for AX-section belt drives requiring a 79-inch outside length cogged V-belt in residential, commercial, and industrial power transmission applications.

Installation Notes

Installation should be performed by a qualified technician. Always de-energize and lock out the equipment before removing or installing a drive belt. Never force a belt onto a sheave using a pry bar, as this can damage the belt cords and reduce service life. After installation, verify proper tensioning and sheave alignment per the equipment manufacturer specifications before returning the unit to service.
