Continental Contitech 20039603 Bx Cogged V-belt 93in

Product Description

The CONTINENTAL CONTITECH 20039603 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 belt delivers reliable torque transfer under demanding operating conditions. The cogged profile reduces bending resistance and improves heat dissipation, making it well-suited for high-load, variable-speed drives. It carries a 93-inch outside length and an 81.8 inside length, weighs 1.1 pounds, and is rated for operating temperatures from -40 degrees F to 140 degrees F. Licensed HVAC technicians and mechanical service professionals install this belt as a direct replacement in belt-driven blower, compressor, and fan assemblies.

This BX90 Torque-Flex cogged V-belt is used in residential and light commercial HVAC systems, agricultural equipment, and industrial machinery where a BX-section belt is specified. Common install scenarios include belt-driven indoor blower motors, condenser fan drives, and general power transmission setups that require an oil-resistant, cogged drive belt. The oil-resistant compound resists degradation from incidental contact with lubricants, extending service life in engine rooms and mechanical equipment rooms.

Key Features

• BX-section cogged profile reduces bending resistance and runs cooler on small-diameter sheaves
• Fiber-Reinforced Vytracord construction provides high tensile strength and dimensional stability
• Oil-resistant compound resists swelling and cracking from lubricant exposure
• Wide operating temperature range: -40 degrees F to 140 degrees F
• 93-inch outside length with 91.8-inch internal length for precise sheave fit
• Torque-Flex style allows use on matched-drive and variable-speed applications

Compatibility

Designed as an OEM-style replacement BX90-section cogged V-belt for belt-driven HVAC blower assemblies, fan drives, and general industrial power transmission systems specifying a BX-section belt at 93 inches outside length.

Installation Notes

Belt replacement is typically performed by licensed HVAC technicians or qualified mechanical service professionals. Disconnect and lock out power to the unit before removing the old belt or adjusting sheave spacing. Do not pry or force the belt over sheave flanges; always loosen the motor mount or tensioner to allow proper installation. Inspect sheave grooves for wear and alignment before installing the new belt, and confirm correct tension per the equipment manufacturer's service documentation.
