Continental Contitech 20039581 Cogged V-belt Bx 71 in

Product Description

The CONTINENTAL CONTITECH 20039581 is a BX-section cogged V-belt engineered for power transmission in HVAC, industrial, and mechanical drive applications. Constructed from fiber-reinforced Vytracord, this belt delivers high tensile strength and flexibility across a wide operating temperature range of -40 degrees F to 140 degrees F (approximately -40 to 60 degrees C). The cogged profile reduces bending resistance, improves heat dissipation, and allows the belt to run on smaller-diameter sheaves without sacrificing efficiency. HVAC technicians, mechanical contractors, and maintenance professionals install this belt as a direct replacement in blower and fan drive systems.

This belt is suited for residential and light commercial HVAC systems, agricultural equipment, compressors, and general industrial machinery that use BX-section drive configurations. The BX68 designation indicates a standardized belt number corresponding to a 71-inch outside length and a 69.80-inch internal length. Its oil-resistant construction makes it appropriate for environments where incidental fluid exposure is a concern, extending service life in demanding conditions.

Key Features

• BX-section cogged profile reduces flex stress and improves sheave grip
• Fiber-reinforced Vytracord construction provides high tensile strength and dimensional stability
• Oil-resistant compound resists degradation from incidental fluid exposure
• Torque-Flex style design accommodates smaller-diameter sheaves
• Wide operating temperature range from -40 degrees C to 60 degrees C
• Standardized BX68 belt number for straightforward cross-referencing

Compatibility

Designed as a standard BX-section cogged V-belt replacement compatible with any drive system specifying a BX68 belt with a 71-inch outside length and standard BX cross-section dimensions.

Installation Notes

Belt replacement is typically performed by HVAC technicians or mechanical maintenance professionals. Disconnect and lock out all power to the unit before removing the old belt or adjusting sheaves. Verify sheave alignment and inspect for groove wear before installing the new belt. Do not pry or force the belt over sheave flanges; always release drive tension to allow proper seating, then re-tension according to the equipment manufacturer's specification.
