Bando AX37 Cogged V-belt Ax Section 39 in 1/2 in Width

Product Description

The BANDO AX37 is a classic cogged V-belt designed for power transmission applications across HVAC, industrial, and agricultural equipment. Built from heat-resistant and oil-resistant rubber, it runs in the AX belt section with a 39-inch outside length, a 1/2-inch width, and a 5/16-inch thickness. The cogged construction reduces bending resistance and heat buildup compared to standard wrapped belts, making it well suited for smaller-diameter sheaves and high-cycle drive systems. Licensed technicians and equipment mechanics install this belt as a direct OEM-style or aftermarket replacement whenever a drive belt shows cracking, glazing, or slip.

The AX37 fits drive systems that call for an AX-section cogged V-belt with a 39-inch outside length (37-inch internal length). Typical applications include residential and light-commercial HVAC blower drives, compressor drives, pump drives, and general power transmission setups where heat and oil exposure are common service conditions. The ARPM-standard sizing ensures interchangeability with other ARPM-compliant AX37 belts across a wide range of equipment.

Key Features

• Cogged construction reduces bending resistance and runs cooler on small-diameter sheaves
• Heat-resistant and oil-resistant rubber compound extends service life in demanding environments
• AX section with 39-inch outside length and 37-inch internal length for precise drive alignment
• 1/2-inch width and 5/16-inch thickness conform to ARPM standard AX37 dimensions
• Classic cogged style compatible with standard AX-section sheaves and pulleys
• Black rubber construction; 0.315 pounds for easy single-belt handling and stocking

Compatibility

Designed as an ARPM-standard AX-section cogged V-belt replacement suitable for any drive system specifying an AX37 belt, including HVAC blower assemblies, compressor drives, and general power transmission equipment requiring a 39-inch outside length AX-section belt.

Installation Notes

Belt replacement is typically performed by HVAC technicians, millwrights, or equipment mechanics. Always de-energize and lock out the equipment before removing the old belt or installing the new one. Never force the belt over sheave flanges with a pry tool, as this can damage the cord structure; loosen the drive motor mount to create slack instead. Inspect sheave grooves for wear, misalignment, and debris before installing the new belt, and verify tension per the equipment manufacturer's deflection specification.
