Continental Contitech 20039615 Bx Cogged V-belt BX105

Product Description

The CONTINENTAL CONTITECH 20039615 is a BX-section cogged V-belt designed for industrial and HVAC drive applications requiring reliable power transmission. Built with Fiber-Reinforced Vytracord construction, this Torque-Flex belt delivers enhanced flexibility and load-carrying capacity compared to standard wrapped belts. The cogged profile reduces bending resistance and heat buildup, extending belt life under continuous-duty conditions. With a 108-inch outside length and an internal length of 106.80 inches, this belt carries the belt number BX105 and is suited for systems where oil resistance and a wide operating temperature range are required.

This belt is appropriate for use in commercial and industrial settings including HVAC air-handling units, refrigeration systems, fan and blower drives, and general power transmission equipment. The BX section and Torque-Flex design make it a practical replacement in drive systems that demand consistent speed ratios and resistance to slippage under variable loads. Licensed HVAC technicians, millwrights, and mechanical contractors typically handle installation and replacement of this belt in scheduled maintenance work.

Key Features

• BX-section cogged profile reduces bending resistance and extends service life
• Fiber-Reinforced Vytracord construction for high tensile strength and durability
• Oil-resistant compound suitable for environments with incidental oil exposure
• Wide operating temperature range: -40 degrees F to 140 degrees F (approximately -40 C to 60 C)
• Torque-Flex design allows use on smaller-diameter sheaves without performance loss
• 108-inch outside length (BX105) for direct replacement compatibility

Compatibility

This belt is identified as BX105 and fits drive systems requiring a BX-section cogged V-belt with a 108-inch outside length. Designed as a direct OEM-style replacement for BX105 belt applications in HVAC, fan, blower, and general industrial drive systems.

Installation Notes

Belt replacement should be performed by a qualified technician with equipment fully de-energized and locked out per applicable OSHA lockout/tagout procedures. Sheaves should be inspected for wear, misalignment, and proper groove profile before installing the new belt. Never pry or force the belt over a sheave flange; always release drive tension by adjusting the motor mount before seating the belt. After installation, verify tension and alignment according to the equipment manufacturer's drive specifications.
