Continental Contitech 20039472 Ax Cogged V-belt AX33

Product Description

The CONTINENTAL CONTITECH 20039472 is a cogged AX-section V-belt designed for power transmission applications in HVAC, industrial, and commercial equipment. Built from fiber-reinforced Vytracord, this Torque-Flex belt delivers flex resistance and dimensional stability under load. The cogged profile reduces bending resistance and heat buildup, making it well-suited for smaller-diameter sheave applications. It measures 35.2 inches outside length with a 34.30-inch internal length. The belt carries oil-resistant properties and is rated for operating temperatures from -40 degrees C to 60 degrees C, giving it a wide service range across seasonal and indoor-outdoor environments.

This AX33 V-belt fits drive systems found in residential and light commercial HVAC equipment, including blower assemblies, air handlers, and condensing units that use AX-section belt drives. It is also applicable in agricultural, pump, and general-purpose industrial drives where a cogged AX belt is specified. HVAC technicians and mechanical service pros typically install this belt during preventive maintenance or belt-failure service calls on belt-driven blower and fan systems.

Key Features

• Cogged profile reduces bending resistance and heat generation on small-diameter sheaves
• Fiber-reinforced Vytracord construction provides tensile strength and flex fatigue resistance
• Oil-resistant compound extends service life in environments with lubricant exposure
• Wide temperature range: -40 degrees C minimum to 60 degrees C maximum
• Torque-Flex style design allows use on variable-speed and backside-idler drive configurations
• Belt Number AX33 for direct cross-reference ordering

Compatibility

Designed as an OEM-style replacement for drive systems requiring an AX-section cogged V-belt. This belt is identified by belt number AX33 and fits any drive system specifying AX33 or a compatible AX-section belt with a 35.2-inch outside length.

Installation Notes

Belt replacement should be performed by a qualified HVAC technician or mechanical service professional. Always de-energize and lock out the equipment before removing drive components. Adjust sheave alignment and belt tension per the equipment manufacturer's specifications before returning the unit to service. Do not pry the belt over sheave flanges, as this can damage the cord structure and reduce belt life.
