Continental Contitech 20039572 Bx Cogged V-belt BX59

Product Description

The CONTINENTAL CONTITECH 20039572 is a BX-section cogged V-belt designed for power transmission in HVAC, industrial, and mechanical drive applications. Built with Fiber-Reinforced Vytracord construction, this belt delivers dependable torque transfer while resisting oil exposure and temperature extremes. The cogged design reduces flex fatigue and heat buildup, improving efficiency over standard wrapped belts. Outside length measures 62 inches, with a belt internal length of 60.80 inches. The BX59 designation follows standard belt numbering. Rated for operation from -40 degrees F up to 140 degrees F (60 degrees C). HVAC technicians and mechanical contractors rely on this belt for fan drives, blower assemblies, and similar rotating equipment.

This belt is suited for residential and light commercial HVAC systems, air handlers, and general industrial drive applications where a BX-section cogged belt is specified. The Torque-Flex style accommodates smaller pulley diameters common in HVAC blower and condenser fan assemblies. Oil-resistant properties make it appropriate for installations near compressors or machinery where fluid exposure is a concern. Install as a direct replacement wherever a BX59 belt is called for.

Key Features

• BX-section cogged construction reduces bending resistance and extends belt life
• Fiber-Reinforced Vytracord material provides high tensile strength and dimensional stability
• Oil-resistant compound resists degradation in environments with incidental fluid exposure
• Torque-Flex style designed to run on smaller sheave diameters without cracking
• Wide operating temperature range: -40 degrees C to 60 degrees C
• 62-inch outside length with 60.80-inch internal length; BX59 belt number

Compatibility

Designed as a direct replacement for any application specifying a BX59 cogged V-belt. Fits standard BX-section sheaves and pulleys used in HVAC blower drives, condenser fan drives, and general industrial power transmission equipment.

Installation Notes

Installation should be performed by a qualified HVAC technician or mechanic. Disconnect and lock out all power to the equipment before replacing the belt. Relieve sheave tension before removing the old belt and do not roll or force the new belt onto the sheave with a pry bar, as this can damage the cord structure. Check sheave alignment and tension per the equipment manufacturer's specifications after installation.
