Continental Contitech 20042513 Cogged V-belt 3VX 125in

Product Description

The CONTINENTAL CONTITECH 20042513 is a cogged V-belt engineered for high-performance power transmission in demanding drive applications. Built from fiber-reinforced Wingprene rubber, this belt delivers oil resistance and flexible durability across a wide range of operating conditions. The 3VX section designation indicates a narrow, wedge-style profile optimized for high-torque, high-speed drives. With a 125-inch outside length, this belt is suited for larger drive systems found in commercial and industrial HVAC equipment, compressors, and auxiliary mechanical systems. Installation is straightforward for any technician familiar with belt-drive maintenance.

This belt fits drive systems requiring a 3VX section cogged belt with a 125-inch outside length. The cogged design reduces bending resistance, which improves efficiency and reduces heat buildup on smaller-diameter sheaves. The HY-T Wedge Matchmaker cogged style allows it to be matched and run in multi-belt drives where consistent belt length is critical. Typical applications include belt-driven HVAC blower assemblies, air handlers, cooling tower fans, and industrial fan drive systems where oil mist exposure is a factor.

Key Features

• 3VX cogged section reduces bending stress and heat buildup on small-diameter sheaves
• Fiber-reinforced Wingprene rubber construction for strength and flexibility
• Oil-resistant compound resists degradation in environments with petroleum mist or splash
• HY-T Wedge Matchmaker cogged style supports matched multi-belt drive setups
• 125-inch outside length suits larger commercial and industrial drive configurations

Compatibility

Designed as an OEM-style replacement for drive systems requiring a 3VX section cogged V-belt with a 125-inch outside length. Cross-reference belt number 3VX1250 when verifying fitment against existing drive documentation.

Installation Notes

Belt replacement should be performed by a qualified technician with the drive system fully de-energized and locked out per OSHA lockout/tagout procedures. Inspect sheaves for wear, misalignment, and debris before installing the new belt. Never pry a belt over a sheave flange; always release drive tension using the motor adjustment or idler before seating the belt. After installation, verify proper belt tension and sheave alignment before returning the system to service.
