Continental Contitech 20039505 Cogged Ax V-belt 68.2 in

Product Description

The CONTINENTAL CONTITECH 20039505 is a cogged AX-section V-belt designed for power transmission in industrial and HVAC drive applications. Built with Fiber-Reinforced Vytracord construction, this belt delivers high tensile strength and flexibility under load. The cogged profile reduces bending resistance, which improves efficiency and extends belt life compared to standard raw-edge belts. With an outside length of 68.2 inches and a belt number designation of AX66, this unit suits a wide range of sheave-driven equipment. The oil-resistant compound adds durability in environments where fluid exposure is a factor. Installation is performed by qualified mechanical or HVAC technicians working on belt-driven systems.

This belt is suited for residential and light commercial HVAC systems, refrigeration units, air compressors, and general industrial machinery that use AX-section drive configurations. The Torque-Flex style designation indicates suitability for drives requiring flexibility and consistent torque transfer across varying load conditions. It handles operating temperatures from -40 degrees F up to approximately 140 degrees F, making it appropriate for both cold-storage and high-ambient equipment installations. Technicians replacing worn or cracked belts on blower assemblies, fan drives, and compressor drives will find this belt a direct fit for AX66-specification drives.

Compatibility

Designed as a direct replacement for AX66-designation cogged V-belts used in AX-section sheave drive systems across HVAC, refrigeration, and general industrial power transmission equipment.

Installation Notes

Installation should be performed by a qualified HVAC technician or mechanical drive specialist. Always de-energize and lock out the equipment before removing or installing drive belts. Slacken the drive by adjusting the motor or idler mount before seating the belt — never force a belt over a sheave with a pry tool, as this can damage the cord structure. After installation, verify proper tension and alignment per the equipment manufacturer's specification before returning the unit to service.
