Continental Contitech 20039565 BX52 Cogged V-belt 55 in

Product Description

The CONTINENTAL CONTITECH 20039565 is a BX52 cogged V-belt designed for high-torque power transmission in HVAC, industrial, and agricultural drive systems. Built with Fiber-Reinforced Vytracord construction, this Torque-Flex belt delivers superior flexibility and load-carrying capacity compared to standard wrapped belts. The cogged profile reduces bending resistance, runs cooler, and improves efficiency on smaller sheave diameters. It has an outside length of 55 inches and an internal length of 53.80 inches. HVAC technicians, maintenance mechanics, and equipment service pros install this belt on blower drives, fan assemblies, and pump drives.

This BX-section cogged belt is suited for residential and light commercial HVAC systems, refrigeration equipment, compressors, and general industrial drive applications where oil resistance and wide temperature range performance are required. The BX section is a standard industrial profile, making it a common replacement choice on belt-driven blower and condenser fan assemblies as well as machine drive systems operating in demanding environments.

Key Features

• Cogged profile reduces flex fatigue and runs cooler on small-diameter sheaves
• Fiber-Reinforced Vytracord construction provides high tensile strength and dimensional stability
• Oil-resistant compound resists degradation in environments with incidental oil or grease exposure
• Wide operating temperature range: -40 degrees F minimum to 140 degrees F maximum (equivalent to -40C to 60C)
• Torque-Flex design allows use on variable-speed and standard fixed-speed drives
• BX section profile is interchangeable with standard BX52 belt designation

Compatibility

Designed as an OEM-style replacement BX52 cogged V-belt for any drive system requiring a BX-section belt with a 55-inch outside length and 53.80-inch internal length.

Installation Notes

Belt replacement should be performed by a qualified HVAC technician or mechanical service professional. Always de-energize and lock out the equipment before removing or installing drive belts. Adjust sheave spacing to allow belt installation without prying, then tension according to the equipment manufacturer's deflection or tensioning specification. Never mix old and new belts on multi-belt drive configurations, as uneven stretch causes premature wear.
