Continental Contitech 20039540 AX110 V-belt 112.2 in

Product Description

The CONTINENTAL CONTITECH 20039540 is an AX-section cogged V-belt designed for power transmission applications in HVAC, industrial, and mechanical drive systems. Sold under the belt number AX110, it features a Fiber-Reinforced Vytracord construction in the Torque-Flex style, which allows the belt to flex around smaller sheave diameters while maintaining tensile strength. The outside length is 112.2 inches with an internal length of 111.30 inches. The cogged profile reduces heat buildup and improves flexibility compared to a standard wrapped belt, making it well-suited for variable-speed and high-torque drive applications. The belt weighs 0.8 pounds.

This belt is used in belt-drive systems found in residential and commercial HVAC blower assemblies, air handlers, cooling towers, agricultural equipment, and general industrial machinery. The AX section is a standard cogged profile that fits matching AX-section sheaves and pulleys. It is a direct replacement for any application specifying an AX110 belt. Installation is typically performed by HVAC technicians, millwrights, or maintenance mechanics during scheduled drive maintenance or belt failure service calls.

Key Features

• AX-section cogged profile fits standard AX-matched sheaves and pulleys
• Fiber-Reinforced Vytracord construction provides high tensile strength and flex fatigue resistance
• Torque-Flex style design allows use on smaller sheave diameters with reduced heat buildup
• 112.2-inch outside length with 111.30-inch internal length for precise drive sizing
• Lightweight at 0.8 pounds for easy handling during installation
• Single-piece packaging with no minimum order above one unit

Compatibility

Designed as an OEM-style replacement for any belt-drive system specifying an AX110 cogged V-belt with an AX cross-section and 112.2-inch outside length.

Installation Notes

Power down and lock out the equipment before removing the old belt or accessing the drive assembly. Loosen the motor mounting bolts to relieve belt tension before removal and installation — never pry or force a V-belt over a sheave under tension. After seating the new belt, adjust sheave alignment and belt tension per the equipment manufacturer's specifications before returning the unit to service. Inspect sheave grooves for wear or glazing at the time of belt replacement.
