Continental Contitech 20039559 BX46 Cogged V-belt Bx Section

Product Description

The CONTINENTAL CONTITECH 20039559 is a BX46 cogged V-belt designed for demanding power-transmission applications in HVAC, industrial, and agricultural drive systems. Built with Fiber-Reinforced Vytracord construction, this belt delivers high tensile strength with reduced stretch over its service life. The cogged profile lowers bending resistance, improving efficiency and flexibility on smaller-diameter sheaves. With an outside length of 49 inches and an internal length of 47.80 inches, this BX-section belt installs into standard BX-groove pulleys. HVAC technicians and mechanical contractors specify this belt type for blower-drive and equipment-drive applications where oil exposure and wide temperature swings are factors.

This belt is suited for residential and light commercial HVAC blower assemblies, refrigeration condensing unit fan drives, and general industrial belt-drive systems. The oil-resistant compound makes it appropriate for environments where belt contact with lubricants or hydraulic fluid is possible. The Torque-Flex design allows the belt to run cooler and quieter than conventional raw-edge belts in similar drive configurations. It performs across a rated temperature range of -40 degrees C to 60 degrees C, making it viable in outdoor condensing unit applications subject to cold-weather startups.

Key Features

• Cogged BX-section profile reduces bending resistance and heat buildup on small-sheave drives
• Fiber-Reinforced Vytracord tensile cords provide high strength with low elongation
• Oil-resistant compound resists degradation from incidental lubricant or fluid contact
• Torque-Flex construction allows use on tighter center-distance drives
• Rated from -40 degrees C to 60 degrees C for year-round outdoor and indoor service
• Outside length of 49 inches fits standard BX46 drive configurations

Compatibility

Designed as an OEM-style replacement for BX-section cogged V-belt drive systems requiring a BX46 belt with a 49-inch outside length and 47.80-inch internal length.

Installation Notes

Belt replacement should be performed by a qualified HVAC technician or mechanical contractor. Always de-energize and lock out the equipment before removing the belt guard or drive components. Adjust sheave center distance to allow belt installation without forcing the belt over the pulley flange, then re-tension to the drive manufacturer's specification. Inspect sheave grooves for wear before installing a new belt, as worn grooves accelerate belt deterioration.
