Continental Contitech 20039477 AX38 Cogged V-belt 40.2 in

Product Description

The CONTINENTAL CONTITECH 20039477 is a cogged V-belt in the AX section, designed for industrial and HVAC drive applications requiring reliable power transmission. Built with Fiber-Reinforced Vytracord construction, this belt delivers high tensile strength and dimensional stability under load. The outside length measures 40.2 inches with an internal length of 39.30 inches, and the cogged underside reduces bending resistance for improved efficiency on smaller-diameter sheaves. It is also oil-resistant, making it suitable for environments where belt contact with petroleum-based fluids is a concern. Licensed technicians and mechanical contractors install this belt on fan, blower, and motor drive assemblies.

This AX38 cogged V-belt fits residential and light commercial HVAC systems, industrial fan drives, agricultural equipment, and general power transmission setups that call for an AX-section belt. The Torque-Flex style designation indicates the cogged profile is engineered for high-flex applications, including drives using smaller sheave diameters where a standard wrapped belt would see excessive heat buildup and premature wear. The oil-resistant compound adds service life in compressor rooms and mechanical spaces where fluid exposure is common.

Key Features

• AX section cogged profile reduces bending resistance and heat buildup on small-diameter sheaves
• Fiber-Reinforced Vytracord construction provides high tensile strength and dimensional stability
• Oil-resistant compound extends service life in environments with petroleum fluid exposure
• Wide operating temperature range from -40 degrees F to approximately 140 degrees F
• Torque-Flex style suited for high-flex, variable-speed, and compact drive configurations
• Outside length 40.2 inches, internal length 39.30 inches for precise sheave fit

Compatibility

Designed as a direct replacement for AX38 section cogged V-belts on HVAC blower drives, industrial fan assemblies, and general power transmission equipment specifying an AX-section belt with a 40.2-inch outside length.

Installation Notes

Power down and lock out the drive unit before removing or installing the belt. Do not use tools to pry or force the belt over sheave flanges, as this can damage the tensile cords and reduce belt life. After installation, verify sheave alignment and set belt tension according to the equipment manufacturer's deflection specifications. Inspect sheave grooves for wear before installing a new belt, as worn grooves accelerate belt degradation.
