Bando AX91 Cogged V-belt Ax Section 93 in 1/2 in

Product Description

The BANDO AX91 is a classic cogged V-belt designed for power transmission applications across HVAC, refrigeration, agricultural, and industrial equipment. The cogged construction reduces bending resistance, allowing the belt to run cooler and more efficiently than a comparable smooth-bottom belt. With an outside length of 93 inches, a belt width of 0.5 inches, and a thickness of 0.31 inches, this AX-section belt is built from rubber and rated for heat and oil resistance. It is a direct-fit replacement for equipment originally specifying the AX91 belt designation and is installed by HVAC technicians, refrigeration mechanics, and general equipment service professionals.

The AX91 is suited for residential and light commercial HVAC systems, condensing units, air handlers, and a wide range of belt-driven industrial machinery where an AX-section cogged belt is called out by the OEM. The cogged profile improves flexibility on smaller-diameter sheaves and pulleys, making it a common choice in tight drive configurations. This belt meets ARPM standards, confirming dimensional and performance consistency across manufacturers for cross-reference and replacement purposes.

Key Features

• Cogged AX-section construction reduces bending resistance and heat buildup during operation
• Heat resistant and oil resistant rubber compound for demanding service environments
• Outside length of 93 inches with an internal length of 91 inches for accurate sheave and pulley sizing
• Belt width of 0.5 inches and thickness of 0.31 inches conform to AX-section dimensional standards
• Meets ARPM standards for interchangeability with other AX91-designated belts
• Classic cogged style compatible with fixed-pitch drives on standard V-belt sheaves

Compatibility

Designed as an OEM-style replacement for any drive system specifying an AX-section cogged V-belt with the AX91 designation. Cross-references directly to belt number AX91 per ARPM dimensional standards.

Installation Notes

AX-section V-belts are installed by HVAC technicians, refrigeration mechanics, and equipment service professionals. Always de-energize and lock out the equipment before removing or installing drive belts. Loosen the motor mounting hardware to relieve belt tension before removal, and never pry the belt over a sheave under tension. After installation, adjust tension to the equipment manufacturer's specification and verify sheave alignment before returning the unit to service.
