Bando AX29 Cogged V-belt Ax Section 31 in 1/2 in Width

Product Description

The BANDO AX29 is a classic cogged V-belt in the AX section, designed for power transmission applications across HVAC equipment, agricultural machinery, industrial drives, and general-purpose mechanical systems. Measuring 31 inches in outside length with a 1/2-inch belt width and 5/16-inch thickness, this rubber belt features a cogged construction that increases flexibility, reduces heat buildup, and improves efficiency over standard smooth V-belts. The cogged profile allows tighter bend radii, making it well suited for smaller-diameter sheaves common in HVAC blower assemblies and compressor drives. HVAC technicians, millwrights, and general maintenance professionals are the primary installers of this belt type.

The AX29 fits drives that call for an AX-section cogged V-belt with a 29-inch internal length and 31-inch outside length. It is commonly used in residential and light commercial HVAC systems, fan and blower drives, pump drives, and small engine applications. The cogged design is especially effective in variable-speed and high-cycle applications where heat resistance and flexibility are critical. This belt meets ARPM standards and carries heat-resistant and oil-resistant properties suited to demanding mechanical environments.

Key Features

• Cogged construction reduces flex resistance and heat buildup on small-diameter sheaves
• Heat-resistant and oil-resistant rubber compound extends service life in demanding drive environments
• AX section with 1/2-inch width and 5/16-inch thickness for precise sheave fitment
• Outside length of 31 inches and internal length of 29 inches for accurate belt selection
• Meets ARPM standards for V-belt dimensional and performance requirements
• Classic cogged style compatible with standard AX-section sheaves and pulleys

Compatibility

Designed as a direct replacement for any drive requiring an AX-section cogged V-belt with a 31-inch outside length and 29-inch internal length, conforming to ARPM dimensional standards.

Installation Notes

Belt replacement should be performed by a qualified technician with the drive fully de-energized and locked out per applicable safety codes. Never pry a V-belt over a sheave flange; always release drive tension before removal and installation. After installing the new belt, verify proper tensioning according to the equipment manufacturer's deflection specification before returning the drive to service. Inspect sheave grooves for wear or misalignment before installing a replacement belt.
