Continental Contitech 20039509 Ax Cogged V-belt 72.2 in

Product Description

The CONTINENTAL CONTITECH 20039509 is an AX-section cogged V-belt built for demanding drive applications in HVAC, industrial, and mechanical power-transmission systems. Constructed from Fiber-Reinforced Vytracord, this belt carries the AX70 designation with a 72.2-inch outside length and a 71.30-inch internal length. The cogged profile reduces bending resistance and heat buildup, making it well-suited for smaller-diameter sheaves and variable-speed drives. The oil-resistant compound protects belt integrity in environments where fluid exposure is a factor. Licensed HVAC technicians, millwrights, and mechanical service technicians are the primary installers of this belt type.

This belt is designed for use in residential and light commercial HVAC blower drive assemblies, condensing unit fan drives, refrigeration equipment, and general industrial machinery where an AX-section cogged belt is specified. The Torque-Flex style construction allows the belt to flex efficiently around tighter sheave configurations without sacrificing load capacity. It operates reliably across a temperature range of -40 degrees C to 60 degrees C, making it suitable for both outdoor condensing unit applications and cold-storage environments.

Key Features

• AX-section cogged profile reduces flex fatigue and heat on small-diameter sheaves
• Fiber-Reinforced Vytracord construction provides high tensile strength and dimensional stability
• Oil-resistant compound resists degradation in environments with fluid exposure
• Torque-Flex style supports efficient power transmission on variable-speed and tight-center drives
• Wide operating temperature range: -40 degrees C minimum to 60 degrees C maximum
• Sold individually with no minimum order beyond a single unit

Compatibility

Designed as an OEM-style replacement for drive systems requiring an AX70 cogged V-belt with a 72.2-inch outside length and AX cross-section profile.

Installation Notes

Belt replacement should be performed by a qualified technician following applicable equipment lockout and tagout procedures before servicing any drive assembly. Always check sheave condition and alignment before installing a new belt, and never pry a belt onto a sheave — release tension on the drive first. Consult the equipment manufacturer's belt tension specifications, using a tension gauge where applicable, to avoid premature wear from under- or over-tensioning.
