Bando AX43 Cogged V-belt Ax Section 45 in 1/2 in

Product Description

The BANDO AX43 is a classic cogged V-belt designed for power transmission in HVAC, agricultural, industrial, and general mechanical drive applications. Built from rubber with a cogged profile, it reduces heat buildup, increases flexibility, and improves efficiency over standard wrapped belts. The belt measures 45 inches outside length with a 1/2 inch width and 5/16 inch thickness. Its heat-resistant and oil-resistant construction extends service life in demanding environments. Licensed HVAC technicians, equipment mechanics, and maintenance professionals install this belt as a direct drive component in blower, fan, and pump drive systems.

The AX43 is suited for residential and light commercial HVAC blower drives, compressor drives, agricultural equipment, and general-purpose power transmission wherever an AX-section cogged belt is specified. The cogged design allows the belt to run on smaller-diameter sheaves with less flex fatigue compared to standard V-belts, making it a common choice in high-cycle or continuous-duty drive systems where heat and oil exposure are concerns.

Key Features

• Cogged profile reduces flex fatigue and operates efficiently on small-diameter sheaves
• Heat-resistant and oil-resistant rubber construction for extended service life
• AX section with 45 inches outside length and 43 inches internal length
• 1/2 inch width and 5/16 inch thickness for precise sheave fitment
• Meets ARPM standards for dimensional accuracy and performance
• Black rubber construction, classic cogged style

Compatibility

Designed as a direct replacement for AX43-section cogged V-belts in HVAC blower drives, fan drives, pump drives, and general industrial power transmission systems requiring an AX-section belt with 45 inches outside length.

Installation Notes

Installation is typically performed by HVAC technicians, millwrights, or qualified maintenance personnel. Disconnect and lock out all power to the drive system before removing or installing the belt. Adjust sheave center distance to allow belt installation without prying or forcing, then tension according to drive manufacturer specifications. Inspect sheave grooves for wear or misalignment before installing a new belt.
