Continental Contitech 20039487 Ax Cogged V-belt AX48

Product Description

The CONTINENTAL CONTITECH 20039487 is a cogged AX-section V-belt designed for power transmission in HVAC, agricultural, industrial, and commercial equipment drives. Built with Fiber-Reinforced Vytracord construction, this Torque-Flex belt delivers consistent grip and flexibility across demanding duty cycles. The 50.2-inch outside length and 49.30-inch internal length place it in the standard AX48 designation. At 0.3 pounds, it is a lightweight single-belt replacement. The oil-resistant compound resists common shop-floor and mechanical-room contaminants, extending service life in environments where fluid exposure is likely. HVAC technicians, millwrights, and mechanical contractors install this belt on motor-to-blower and motor-to-compressor drive setups.

This belt is suited for residential and light commercial HVAC blower drives, refrigeration unit fan drives, and general industrial equipment where an AX-section cogged belt is specified. The cogged profile reduces bending resistance compared to a standard wrapped belt, making it well-suited for smaller-diameter sheaves and variable-speed applications. It performs across a wide temperature range, from -40 degrees F equivalent low-temperature conditions up to approximately 140 degrees F, covering most mechanical room and rooftop environments.

Key Features

• AX48 designation — 50.2-inch outside length, 49.30-inch internal length
• Cogged Torque-Flex profile reduces bending stress on small-diameter sheaves
• Fiber-Reinforced Vytracord tensile cord for high load capacity and dimensional stability
• Oil-resistant compound suitable for mechanical rooms and equipment with fluid exposure
• Wide operating temperature range: -40 degrees C to 60 degrees C
• Single-belt packaging, MOQ of 1

Compatibility

Designed as an OEM-style replacement for equipment requiring an AX48 cogged V-belt in AX-section drives. The AX48 belt number is an industry-standard designation, and this belt fits any sheave or pulley system calling for an AX48 cross-section cogged belt.

Installation Notes

Installation should be performed by a qualified HVAC technician or mechanical contractor with the drive system fully de-energized and locked out per OSHA lockout/tagout procedures. Never force a belt onto a sheave with a pry bar — always release tension by adjusting motor position or the tensioner before seating the belt. After installation, verify belt tension and alignment per the equipment manufacturer's specification before returning the system to service. Inspect sheave grooves for wear before installing a new belt to avoid premature failure.
