Continental Contitech 20039596 BX83 Cogged V-belt 86 in

Product Description

The CONTINENTAL CONTITECH 20039596 is a BX-section cogged V-belt designed for demanding power transmission applications in HVAC, industrial, and mechanical drive systems. Built with Fiber-Reinforced Vytracord construction, this belt delivers high tensile strength and flexibility under load. The cogged profile reduces bending resistance and heat buildup, improving efficiency over standard wrapped belts. With an outside length of 86 inches and an internal length of 84.80 inches, it fits a wide range of drive configurations. Licensed technicians and mechanical contractors install this type of belt during equipment startup, routine maintenance, and belt replacement service.

This BX83 cogged V-belt is suited for residential and light commercial HVAC units, fans, blowers, compressors, and general industrial drive systems that use BX-section belt drives. The Torque-Flex design accommodates high-torque applications and tight-radius sheaves where standard belts would crack or wear prematurely. Its oil-resistant compound makes it appropriate for environments where incidental oil exposure is a concern. The belt operates across a wide temperature range, from -40 degrees F equivalent low to 140 degrees F equivalent high, covering most mechanical room and rooftop equipment conditions.

Key Features

• BX-section cogged profile reduces bending resistance and extends belt life compared to standard wrapped belts
• Fiber-Reinforced Vytracord construction provides high tensile strength under sustained load
• Torque-Flex style handles high-torque drives and small-diameter sheave applications
• Oil-resistant compound protects against incidental exposure in mechanical and equipment rooms
• Wide operating temperature range: -40 degrees C minimum to 60 degrees C maximum
• Outside length of 86 inches with internal length of 84.80 inches for precise drive sizing

Compatibility

Designed as an OEM-style replacement for BX-section cogged V-belt drives in residential and commercial HVAC, fan, blower, and general industrial power transmission systems using BX83 belt sizing.

Installation Notes

Belt replacement is typically performed by licensed HVAC technicians or mechanical contractors. Always de-energize and lock out the equipment before removing the old belt or installing a new one. Adjust sheave alignment and belt tension according to equipment manufacturer specifications before returning the drive to service. Do not pry the belt over sheave flanges, as this can damage the cord structure and reduce belt life.
