Continental Contitech 20039549 Bx Cogged V-belt 38in

Product Description

The CONTINENTAL CONTITECH 20039549 is a BX-section cogged V-belt designed for power transmission applications in HVAC, industrial, and mechanical drive systems. Built with Fiber-Reinforced Vytracord construction, this belt delivers consistent torque transfer under demanding load conditions. The cogged profile reduces bending resistance, which improves flexibility and extends belt life on smaller-diameter sheaves. With an outside length of 38.0 inches and an internal length of 36.80 inches, it matches the BX35 belt number designation. Oil resistance and a wide operating temperature range make it suited to both indoor mechanical rooms and outdoor equipment installations.

This belt is a direct-fit replacement in applications calling for a BX35 cogged V-belt. Common install scenarios include belt-drive HVAC equipment such as air handlers, blowers, and condenser fans, as well as general industrial drive systems using BX-section sheave arrangements. The Torque-Flex style is engineered for high-torque, variable-load drives where a standard wrapped belt may slip or fatigue prematurely. HVAC technicians and mechanical contractors routinely specify BX-section cogged belts for residential and light-commercial belt-drive blower assemblies.

Key Features

• BX-section cogged profile reduces flex stress and improves efficiency on smaller sheaves
• Fiber-Reinforced Vytracord construction provides high tensile strength and dimensional stability
• Oil-resistant compound resists degradation in environments with incidental fluid exposure
• Torque-Flex style rated for high-torque and variable-load drive applications
• Wide operating temperature range: -40 degrees F to 140 degrees F (-40 C to 60 C)
• Outside length 38.0 inches, internal length 36.80 inches; BX35 belt number

Compatibility

Designed as a direct OEM-style replacement for applications requiring a BX35 cogged V-belt in BX-section sheave drives. Belt number BX35 is the standard designation for this size and section.

Installation Notes

Belt replacement should be performed by a qualified HVAC technician or mechanical contractor with the drive system fully de-energized and locked out per OSHA lockout/tagout procedures. Never force a belt onto a sheave without first loosening the motor mount to relieve tension. Inspect sheaves for wear, misalignment, and debris before installing the new belt, and align sheaves within manufacturer tolerances using a straightedge or laser alignment tool. Proper tensioning is critical to belt life and drive efficiency.
