Continental Contitech 20039580 Bx Cogged V-belt 70 in

Product Description

The CONTINENTAL CONTITECH 20039580 is a BX-section cogged V-belt designed for power transmission applications in HVAC, industrial, and mechanical drive systems. Built with Fiber Reinforced Vytracord construction, this Torque-Flex belt delivers improved flexibility and reduced bending stress compared to standard wrapped belts. The cogged profile increases surface grip, reduces heat buildup, and allows the belt to run on smaller-diameter sheaves without sacrificing load capacity. With an outside length of 70 inches and an internal length of 68.80 inches, it is sized for mid-to-large drive configurations. HVAC technicians, mechanical contractors, and maintenance professionals install this belt in blower and fan drive assemblies across a wide range of equipment.

This belt is suited for residential and commercial HVAC blower drives, refrigeration condensing unit fan drives, agricultural equipment, and general industrial power transmission setups. The BX section designation makes it a direct cogged replacement for standard B-section belt applications where added efficiency and longer service life are required. The oil-resistant compound helps maintain belt integrity in environments where minor oil or grease exposure is likely, such as mechanical rooms and equipment closets.

Key Features

• BX-section cogged profile for use on standard B-section sheaves with improved flexibility
• Fiber Reinforced Vytracord construction for high tensile strength and dimensional stability
• Oil-resistant compound resists degradation in environments with incidental oil or grease exposure
• Torque-Flex design reduces heat buildup and bending stress for longer service life
• Rated for operating temperatures from -40 degrees F to 140 degrees F (approximately -40 C to 60 C)
• Outside length of 70 inches fits mid-to-large blower and fan drive configurations

Compatibility

The BX67 designation corresponds to a standard BX-section cogged V-belt with a 70-inch outside length and 68.80-inch internal length. This belt is a direct cogged upgrade for applications currently using a standard B67 V-belt, and fits any sheave or pulley grooved for BX or B-section belts of equivalent length.

Installation Notes

Installation should be performed by a qualified HVAC technician or mechanical contractor. Always disconnect and lock out power to the drive system before removing or installing belts. Never force a belt onto a sheave with a pry bar; adjust the drive center distance to allow slack for proper seating, then tension according to the equipment manufacturer's deflection specifications. Inspect sheave grooves for wear and alignment before installing a new belt.
