Continental Contitech 20039539 Ax Cogged V-belt AX105

Product Description

The CONTINENTAL CONTITECH 20039539 is a cogged V-belt in the AX section profile, designed for power transmission applications in HVAC, industrial, and mechanical drive systems. Built with Fiber-Reinforced Vytracord construction, this belt delivers reliable torque transfer under demanding conditions. The cogged design reduces flex fatigue and heat buildup compared to standard wrapped belts, making it well suited for smaller sheave diameters and variable-speed drives. With an outside length of 107.2 inches and an internal length of 106.30 inches, this belt is sold as an individual unit. It is rated for operation from -40 degrees C to 60 degrees C and carries oil-resistant properties for use in environments where fluid exposure is possible.

This AX105 belt is used in residential and light commercial HVAC blower drives, compressor drives, and general industrial machinery requiring a cogged AX-section belt. The Torque-Flex style construction allows the belt to bend more easily around smaller pulleys while maintaining consistent grip and tension. HVAC technicians and mechanical maintenance professionals install this belt in belt-driven air handlers, condensing units, and fan assemblies where an AX-profile cogged belt is specified.

Key Features

• Cogged AX section profile reduces bending resistance and heat buildup on smaller sheaves
• Fiber-Reinforced Vytracord construction provides tensile strength and dimensional stability
• Oil-resistant compound suited for environments with incidental fluid exposure
• Wide operating temperature range: -40 degrees C minimum to 60 degrees C maximum
• Torque-Flex style design for improved flexibility and power transmission efficiency
• Sold individually with no minimum order beyond one unit

Compatibility

Designed as an OEM-style replacement AX-section cogged V-belt for belt-driven HVAC blower assemblies, fan drives, and general industrial equipment specifying an AX105 belt profile.

Installation Notes

Installation of this V-belt should be performed by a qualified HVAC technician or mechanical maintenance professional. Always disconnect and lock out electrical power to the unit before removing or installing any drive belt. Do not use tools to force the belt over sheave flanges; adjust the drive component to relieve tension before seating the belt. After installation, verify proper belt tension and sheave alignment per the equipment manufacturer specifications before returning the system to service.
