Continental Contitech 20039643 Bx V-belt 241.5 in

Product Description

The CONTINENTAL CONTITECH 20039643 is a BX section V-belt designed for heavy-duty power transmission applications. Built with Fiber Reinforced Vytracord construction, this Torque-Flex belt delivers reliable flex and torque capacity under load. The belt carries an outside length of 241.5 inches and an internal length of 240.30 inches, placing it in the BX240 designation. It is suited for industrial, commercial HVAC, and mechanical drive systems where a cogged, raw-edge BX profile is specified. At 2.8 pounds, the belt is sized for larger sheave setups and extended drive runs. Installation is handled by mechanical technicians and HVAC service professionals working on belt-driven equipment.

This belt is applied in belt-driven systems requiring a BX section profile, including air handlers, blower assemblies, industrial fans, compressors, and pump drives. The cogged Torque-Flex design allows improved flexibility around smaller sheave diameters and reduces heat buildup during operation. It is commonly used in both commercial HVAC systems and general mechanical power transmission setups where a standard BX240 replacement is required. The Fiber Reinforced Vytracord material provides dimensional stability and resistance to stretching under sustained load conditions.

Key Features

• BX section cogged V-belt profile for improved flexibility and reduced slippage
• Torque-Flex construction allows use on smaller sheave diameters without performance loss
• Fiber Reinforced Vytracord material resists elongation and maintains belt tension over time
• 241.5-inch outside length matches BX240 belt designation
• Raw-edge design improves sheave contact and power transfer efficiency

Compatibility

Designed as an OEM-style replacement for BX240 belt applications in belt-driven HVAC blowers, industrial fans, compressors, and pump drive systems requiring a BX section V-belt.

Installation Notes

Belt replacement should be performed by a qualified HVAC technician or mechanical service professional. De-energize all equipment and lock out and tag out the drive system before removing or installing the belt. Adjust sheave center distance to allow belt installation without forcing the belt over the sheave flanges, then re-tension to the drive manufacturer's specification. Inspect sheaves for wear or misalignment before installing a new belt, as worn grooves will reduce belt service life.
