Continental Contitech 20039470 AX31 Cogged V-belt 33.2 in

Product Description

The CONTINENTAL CONTITECH 20039470 is a Torque-Flex cogged V-belt designed for power transmission applications in HVAC, industrial, and mechanical drive systems. Built with Fiber-Reinforced Vytracord construction, this AX-section belt delivers consistent grip and reduced flexing resistance under load. The cogged profile lowers bending stress on smaller sheaves and improves heat dissipation during operation. With a 33.2-inch outside length and an oil-resistant compound, it holds up in environments where fluid exposure is a regular concern. Licensed trades including HVAC technicians and mechanical contractors rely on this belt for reliable drive performance in both belt-drive blower assemblies and equipment drive trains.

This belt fits standard AX-section sheaves and pulley systems common in residential and light commercial HVAC air handlers, condensing units, and general mechanical equipment. It is identified as belt number AX31, making cross-referencing against OEM specifications and drive catalogs straightforward. The cogged design makes it well suited for fractional and standard horsepower drives with smaller sheave diameters where a raw-edge or standard wrapped belt would flex less efficiently. Oil-resistant materials extend service life in machine rooms and utility spaces where belt splash exposure occurs.

Key Features

• AX-section cogged profile reduces bending stress on small-diameter sheaves
• Fiber-Reinforced Vytracord construction provides tensile strength and dimensional stability
• Oil-resistant compound resists degradation from incidental fluid exposure
• Wide operating temperature range: -40 degrees F to approximately 140 degrees F (-40 C to 60 C)
• Belt number AX31 simplifies OEM cross-referencing and replacement identification
• Single-belt packaging with no minimum order quantity above one unit

Compatibility

Designed as an OEM-style replacement for AX-section cogged V-belt drives requiring a 33.2-inch outside length belt, designated AX31, in residential and commercial equipment applications.

Installation Notes

Always de-energize and lock out the equipment before removing or installing a drive belt. Verify sheave alignment and check sheave grooves for wear before installing a new belt. Do not pry or roll a cogged V-belt over sheave flanges under tension, as this can damage the tensile cord and reduce service life. Follow the equipment manufacturer's belt tension guidelines using a tension gauge appropriate for AX-section belts.
