Bando AX27 Cogged V-belt Ax Section 29 in 1/2 in Width

Product Description

The BANDO AX27 is a classic cogged V-belt in AX section, built for power transmission applications across HVAC equipment, agricultural machinery, and general industrial drives. The cogged construction reduces bending resistance, which improves flexibility and heat dissipation compared to a standard wrapped belt. This belt measures 29 inches outside length with a 1/2 inch width and 5/16 inch thickness. It is manufactured from rubber and rated for both heat and oil resistance. HVAC technicians, equipment mechanics, and maintenance technicians install this belt on belt-driven blowers, fans, pumps, and compressor drives.

The AX27 is suited for residential and light commercial HVAC air handlers, condenser fans, and belt-driven blower assemblies where an AX section belt is specified. Its cogged profile allows it to run on smaller diameter sheaves without the flex fatigue that affects standard V-belts. The heat and oil resistance ratings make it appropriate for mechanical rooms and equipment enclosures where elevated temperatures or minor fluid exposure are common service conditions.

Key Features

• Cogged AX section design reduces bending resistance for improved efficiency on small-diameter sheaves
• Outside length of 29 inches with 27 inch internal length for precise drive sizing
• 1/2 inch belt width and 5/16 inch thickness for standard AX sheave groove fitment
• Rubber construction rated heat resistant and oil resistant
• Meets ARPM standards for V-belt dimensions and performance
• Classic cogged style compatible with a wide range of OEM and aftermarket sheaves

Compatibility

Designed as a direct replacement for any drive requiring an AX section cogged V-belt with a 29 inch outside length and 1/2 inch width. Cross-references by belt number AX27 across standard ARPM-dimensioned sheave systems.

Installation Notes

Installation is performed by HVAC technicians or qualified maintenance mechanics. Disconnect and lock out all power to the unit before removing the old belt or installing the replacement. Verify sheave alignment and condition before fitting the new belt — misaligned or worn sheaves accelerate belt wear. Do not pry or force the belt over sheave flanges; loosen the motor mount to relieve tension, seat the belt properly, then re-tension to the drive manufacturer's specification.
