Continental Contitech 20039569 Bx Cogged V-belt BX56

Product Description

The CONTINENTAL CONTITECH 20039569 is a BX-section cogged V-belt designed for power transmission applications in HVAC, industrial, and agricultural equipment. Built with fiber-reinforced Vytracord construction, this belt delivers consistent torque transfer with reduced heat buildup compared to standard wrapped belts. The cogged profile increases flexibility and grip across the pulley face. It carries an outside length of 59 inches and an internal length of 57.80 inches, fitting BX56 drive configurations. HVAC technicians and mechanical contractors install this belt on fan drives, blower assemblies, and compressor drives where a BX-profile belt is specified.

This belt is suited for residential and light commercial HVAC blower drives, refrigeration condenser fan drives, and general-purpose industrial drive systems that call for a BX56 or equivalent cogged V-belt. The oil-resistant construction makes it a reliable choice in equipment environments where fluid exposure is possible. It operates across a wide temperature range, from -40 degrees F on the low end to 140 degrees F on the high end, supporting year-round service in varied climates and mechanical rooms.

Key Features

• BX-section cogged profile reduces bending resistance and heat buildup on smaller-diameter pulleys
• Fiber-reinforced Vytracord construction for high tensile strength and dimensional stability
• Oil-resistant compound extends service life in environments with fluid exposure
• Wide operating temperature range: -40 degrees C to 60 degrees C (-40 degrees F to 140 degrees F)
• Outside length of 59 inches with internal length of 57.80 inches for precise drive sizing
• Torque-Flex style for smooth, efficient power transfer under variable loads

Compatibility

Designed as an OEM-style replacement BX56 cogged V-belt for drives specifying a BX-section belt with a 59-inch outside length.

Installation Notes

Installation should be performed by a qualified HVAC technician or mechanical contractor. Always de-energize and lock out the equipment before removing or installing the belt. Adjust drive tension according to the equipment manufacturer's deflection specification — do not use a pry bar to force the belt over pulleys, as this can damage the cord structure. Inspect pulleys for wear, misalignment, and debris before installing a new belt.
