Continental Contitech 20039638 Bx Section Cogged V-belt 183 in

Product Description

The CONTINENTAL CONTITECH 20039638 is a BX-section cogged V-belt designed for power transmission in industrial and HVAC drive applications. Built with Fiber-Reinforced Vytracord construction, this belt delivers high tensile strength and dimensional stability under load. The cogged (Torque-Flex) profile reduces bending resistance, allowing operation on smaller-diameter sheaves while improving flexibility and heat dissipation. With an outside length of 183 inches and an internal length of 181.80 inches, it fits standard BX180-designation drives. Oil-resistant compound construction makes it suitable for environments where fluid contamination is a routine concern. HVAC technicians, millwrights, and mechanical contractors install this belt in belt-driven fan, blower, and pump assemblies.

This belt is appropriate for residential and commercial HVAC systems, industrial fan drives, pump drives, and general power transmission equipment that calls for a BX180 cross-section belt. The cogged design suits smaller-sheave configurations common in air handler and rooftop unit blower decks. Its rated operating temperature range of -40 degrees C to 60 degrees C makes it viable for both cold-weather startup and elevated-ambient mechanical rooms. Installers specifying a Torque-Flex or Fiber-Reinforced Vytracord replacement belt for BX180 drives will find this a direct match.

Key Features

• Cogged (Torque-Flex) profile reduces bending resistance for improved flexibility on small-diameter sheaves
• Fiber-Reinforced Vytracord tensile cord construction provides high strength and low stretch under sustained load
• Oil-resistant compound suitable for environments with incidental fluid exposure
• Wide operating temperature range: -40 degrees C minimum to 60 degrees C maximum
• Outside length of 183 inches matches standard BX180 drive specifications
• Single-unit packaging; no minimum order quantity above 1

Compatibility

Designed as a direct replacement for BX180-designation V-belt drives requiring a BX-section cogged belt with a 183-inch outside length and 181.80-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 drive unit before removing the belt guard or servicing sheaves. Do not pry or force the belt over sheave flanges; adjust the drive center distance to allow proper slack for installation. Inspect sheaves for wear, misalignment, and proper groove profile before installing a new belt, as worn sheaves accelerate belt degradation.
