Continental Contitech 20039621 Bx Cogged V-belt 118 in

Product Description

The CONTINENTAL CONTITECH 20039621 is a BX-section cogged V-belt designed for power transmission applications in HVAC, industrial, and agricultural equipment. Built with Fiber Reinforced Vytracord construction, this belt delivers high flexibility and tensile strength under continuous load. The cogged design reduces bending resistance, which improves efficiency and extends belt life compared to standard wrapped belts. At 118 inches outside length and a 116.80-inch internal length, this belt fits a wide range of drive systems requiring BX-section geometry. It is sold individually and weighs 1.4 pounds.

This belt is suited for use in blower drives, fan drives, compressor drives, and general-purpose V-belt drive systems found in both residential and light commercial HVAC equipment as well as industrial machinery. The BX section is a cogged variant of the standard B-section belt, making it a direct upgrade path for applications where reduced slip and lower operating temperature are priorities. Licensed HVAC technicians and mechanical service professionals are the typical installers for this belt type.

Key Features

• BX cogged profile reduces bending resistance and heat buildup compared to standard wrapped B-section belts
• Fiber Reinforced Vytracord construction provides high tensile strength and dimensional stability under load
• Oil resistant construction helps maintain integrity in environments with incidental oil exposure
• Wide operating temperature range: -40 degrees F to 140 degrees F (-40 C to 60 C)
• 118-inch outside length with 116.80-inch internal length for precise drive system fitment
• Belt Number BX115 for cross-reference sourcing

Compatibility

Designed as an OEM-style replacement for BX-section V-belt drive systems requiring a 118-inch outside length. This belt is identified under belt number BX115 and is compatible with any drive system specifying a BX115 belt.

Installation Notes

Installation should be performed by a qualified technician. Always de-energize the equipment and lock out or tag out the power source before removing or installing drive belts. Loosen the drive motor mount to relieve tension before removing the old belt, and never force the belt over sheave grooves, as this can damage the cord structure. After installation, adjust tension to the drive manufacturer's specification and re-check tension after the first few hours of operation.
