Continental Contitech 20039623 Bx Cogged V-belt BX120

Product Description

The CONTINENTAL CONTITECH 20039623 is a BX-section cogged V-belt designed for industrial and HVAC drive applications requiring reliable power transmission under variable load conditions. Built with Fiber-Reinforced Vytracord construction, this belt delivers enhanced tensile strength and dimensional stability over standard rubber belts. The cogged profile reduces bending stress and heat buildup, making it well-suited for smaller-diameter sheaves and high-speed drives. With an outside length of 123 inches and an internal length of 121.80 inches, this belt is sold individually and installed by HVAC technicians, mechanical contractors, and industrial maintenance professionals.

This BX120 Torque-Flex cogged V-belt is used in belt-driven HVAC systems, air handlers, fans, blowers, compressors, and general industrial drive applications. The BX section is a standard cogged profile sized for drives where a classical B-section belt would otherwise be used but improved flexibility and efficiency are needed. It performs across a wide temperature range, rated from -40 degrees F to approximately 140 degrees F, and the oil-resistant compound helps maintain integrity in environments where incidental oil exposure is a factor.

Key Features

• Fiber-Reinforced Vytracord construction for high tensile strength and low stretch
• Cogged profile reduces bending resistance and heat generation on small-diameter sheaves
• Oil-resistant compound suitable for mechanical rooms and industrial environments
• Wide operating temperature range: -40 degrees C to 60 degrees C
• Torque-Flex style for improved flexibility and drive efficiency versus classical V-belts

Compatibility

Designed as an OEM-style replacement for BX120 section cogged V-belt applications in residential and commercial HVAC blower drives, fan drives, and general industrial belt-drive systems using BX-section sheaves.

Installation Notes

BX-section cogged V-belts are installed by HVAC technicians and mechanical maintenance professionals. Always de-energize and lock out the drive unit before removing or installing belts. Never pry or force a belt over a sheave flange; adjust the drive center distance to allow proper belt seating. Check sheave alignment and belt tension after installation and re-inspect tension after the first few hours of operation, as new belts may require re-tensioning.
