Product Description
The CONTINENTAL CONTITECH 20039584 is a BX-section cogged V-belt engineered for demanding power-transmission applications in HVAC, industrial, and mechanical drive systems. Built with a Fiber-Reinforced Vytracord construction and a cogged profile, this belt delivers reduced flexing resistance and improved heat dissipation compared to standard wrapped belts. It measures 74 inches outside length with a 72.80-inch internal length. The cogged design allows use on smaller-diameter sheaves without sacrificing load capacity, making it a practical choice for blower and fan drive assemblies where space is limited.
This BX-section Torque-Flex belt is suited for residential and light commercial HVAC air handlers, blower assemblies, and general-purpose industrial drive systems that require a cogged BX-profile belt. It is rated for operation from -40 degrees F to 140 degrees F (equivalent to -40 degrees C to 60 degrees C), supporting year-round service in both indoor mechanical rooms and outdoor equipment installations. The oil-resistant compound adds durability in environments where incidental contact with lubricants is possible. Belt number BX71 identifies this profile for cross-reference and replacement sourcing.
Key Features
- 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 extends service life in lubrication-prone environments
- Wide operating temperature range: -40 degrees C to 60 degrees C
- BX71 belt number simplifies cross-reference for OEM and aftermarket replacement
- Torque-Flex style supports variable-speed and high-torque drive configurations
Compatibility
Designed as a direct replacement for BX71-profile cogged V-belts used in BX-section sheave drives across residential and commercial HVAC blower assemblies and general industrial power-transmission equipment.
Installation Notes
Installation should be performed by a qualified HVAC technician or mechanical drive specialist. Disconnect and lock out all power to the unit before removing the belt guard or accessing the drive assembly. Never pry or force the belt over sheave flanges; always adjust the motor mount or tensioner to achieve proper slack before seating the belt. After installation, verify belt tension and alignment per the equipment manufacturer’s specifications before restoring power.
