Continental Contitech 20039481 Cogged Ax V-belt 44.2 in

Product Description

The CONTINENTAL CONTITECH 20039481 is a cogged AX-section V-belt designed for power transmission in HVAC, industrial, and mechanical drive applications. Built with Fiber-Reinforced Vytracord construction, this Torque-Flex belt delivers reliable grip and flexibility under demanding load conditions. It measures 44.2 inches in outside length with an internal length of 43.30 inches. The cogged profile reduces bending resistance and heat buildup, making it well-suited for smaller-diameter sheaves and high-cycle drives. HVAC technicians and mechanical equipment service professionals install this belt as a direct replacement in blower and fan drive systems.

This belt is rated for operation from -40 degrees F to 140 degrees F (-40 C to 60 C), making it appropriate for both refrigerated and high-ambient installations. The AX cogged section fits standard AX-profile sheaves commonly found in residential and light commercial air handling units, condensing units, and general mechanical equipment. Its oil-resistant construction helps extend service life in environments where minor oil exposure is likely. Belt number AX42 is the standard industry designation for this size.

Key Features

• Cogged AX-section profile reduces bending resistance on small-diameter sheaves
• Fiber-Reinforced Vytracord construction for high tensile strength and flexibility
• Oil-resistant materials extend belt life in equipment-room environments
• Wide operating temperature range: -40 degrees F to 140 degrees F
• Torque-Flex design allows use on variable-pitch and fixed-pitch drives
• Industry belt number AX42 for straightforward cross-referencing

Compatibility

Designed as an OEM-style replacement for AX-section cogged V-belt applications on standard AX42-profile sheaves in HVAC blower assemblies and general mechanical drive systems.

Installation Notes

Belt replacement is typically performed by HVAC technicians or mechanical service professionals. Always de-energize and lock out the unit before removing the old belt or accessing the drive assembly. Loosen the motor mounting bolts to relieve tension before removing the belt — never force a belt over a sheave with a pry bar, as this can damage belt cords. After seating the new belt, adjust tension per equipment manufacturer specifications and verify sheave alignment before returning the unit to service.
