Continental Contitech 20039510 Ax V-belt 73.2 in Torque-flex

Product Description

The CONTINENTAL CONTITECH 20039510 is an AX-section cogged V-belt designed for demanding power transmission applications in HVAC, agricultural, and industrial equipment. Built with a Fiber-Reinforced Vytracord construction, this belt delivers high tensile strength and flexibility under load. The outside length measures 73.2 inches with an internal length of 72.3 inches, matching the standard AX71 belt designation. The Torque-Flex cogged profile reduces bending resistance, allowing it to run efficiently on smaller-diameter sheaves while maintaining stable power transfer. HVAC technicians, millwrights, and service professionals install this belt as a direct replacement in belt-driven blower, fan, and compressor assemblies.

This AX71 V-belt is suited for residential and light commercial HVAC systems, refrigeration units, and general-purpose machinery that specify an AX-section drive belt. The cogged design improves grip and heat dissipation compared to a standard wrapped belt of the same cross-section, making it a common choice for variable-load applications and systems that run continuously. It is sold individually and requires no special hardware beyond the correct matching sheave or pulley.

Key Features

• AX-section cogged profile reduces bending resistance on small-diameter sheaves
• Fiber-Reinforced Vytracord construction provides high tensile strength and dimensional stability
• 73.2-inch outside length matches AX71 belt number for straightforward cross-referencing
• Torque-Flex style handles shock loads and variable torque conditions
• Sold as a single belt with no minimum order requirement beyond one unit

Compatibility

Designed as a direct replacement for any application specifying an AX71 or AX-section V-belt with a 73.2-inch outside length. Verify sheave groove profile matches the AX cross-section before installation.

Installation Notes

Licensed HVAC technicians and qualified service professionals should de-energize and lock out the equipment before replacing a drive belt. Loosen the motor mounting or idler to relieve tension before removing the worn belt, then seat the new belt fully into the sheave grooves without using tools to force it over the rim. After installation, adjust tension to the equipment manufacturer specification and check alignment across all sheaves before restoring power.
