Continental Contitech 20039475 Ax Cogged V-belt 38.2 in

Product Description

The CONTINENTAL CONTITECH 20039475 is an AX-section cogged V-belt designed for high-efficiency power transmission in HVAC, industrial, and mechanical drive applications. Built with a fiber-reinforced Vytracord construction, this belt delivers dimensional stability and resistance to stretching under load. The cogged profile reduces bending resistance, which lowers heat buildup and improves flexibility around smaller sheaves. With a 38.2-inch outside length and an internal length of 37.30 inches, it fits AX36-designated belt positions. The oil-resistant compound adds durability in environments where fluid contamination is a factor. Licensed HVAC technicians, mechanical contractors, and equipment service techs are the primary installers.

This belt is suited for residential and light commercial HVAC blower assemblies, refrigeration unit drives, compressor drives, and general mechanical equipment where AX-section belts are specified. The Torque-Flex design allows the belt to wrap tighter drive configurations without sacrificing torque capacity. The cogged underside also improves grip on variable-speed drives common in HVAC fan applications. When replacing a worn or cracked belt, the AX36 belt number designation is the correct cross-reference for sourcing this part.

Key Features

• AX-section cogged profile reduces heat buildup and improves flexibility on small-diameter sheaves
• Fiber-reinforced Vytracord construction provides tensile stability and resists elongation
• Oil-resistant compound extends service life in contamination-prone environments
• Torque-Flex style handles demanding drive configurations without slippage
• Rated for operation from -40 degrees F to 140 degrees F (approximately -40 C to 60 C)
• Belt number AX36 — standard cross-reference designation for direct replacement sourcing

Compatibility

Designed as an OEM-style replacement for equipment requiring an AX36 cogged V-belt with a 38.2-inch outside length. Verify sheave groove profile and center-to-center distance against your specific drive configuration before installation.

Installation Notes

Disconnect and lock out all power to the unit before removing the old belt or accessing drive components. Adjust drive center distance to allow belt installation without forcing or prying, which can damage cord structure. After seating the belt in the sheave grooves, set tension according to the equipment manufacturer's specification and re-check tension after initial run-in. HVAC technicians and mechanical contractors should reference applicable equipment service manuals for final tensioning and alignment procedures.
