Continental Contitech 20039617 BX108 Cogged V-belt 111 in

Product Description

The CONTINENTAL CONTITECH 20039617 is a BX-section cogged V-belt designed for industrial and HVAC drive applications requiring dependable power transmission under demanding conditions. Sold under the belt designation BX108, this belt measures 111 inches outside length with an internal length of 109.80 inches. It is constructed from Fiber-Reinforced Vytracord, a tensile cord material that resists stretching and delivers consistent tension across the drive system. The cogged profile reduces bending resistance, which improves efficiency and reduces heat buildup on smaller sheave diameters. This belt is oil-resistant and rated for operation from -40 degrees F to 140 degrees F (approximately -40 C to 60 C). Licensed HVAC technicians, mechanical contractors, and industrial maintenance professionals install this belt type.

This BX108 Torque-Flex cogged V-belt is suited for residential and light commercial HVAC systems, agricultural equipment, industrial machinery, and any belt-driven application calling for a BX-section belt of 111 inches outside length. The cogged design makes it well-matched to variable-speed drives and setups with smaller pulley diameters where a standard wrapped belt would experience excessive flexing losses. The oil-resistant compound adds service life in environments where belt surfaces may contact petroleum-based fluids.

Key Features

• BX-section cogged profile reduces flexing losses and runs cooler on small-diameter sheaves
• Fiber-Reinforced Vytracord construction resists elongation and maintains drive tension
• Oil-resistant compound extends service life in contaminated environments
• Wide operating temperature range: -40 degrees F to 140 degrees F
• Torque-Flex designation indicates suitability for variable-speed and high-torque drive applications
• Outside length of 111 inches; internal length of 109.80 inches for accurate sheave matching

Compatibility

Designed as a direct replacement for BX108 belt applications. Fits any drive system specifying a BX-section cogged V-belt with 111 inches outside length.

Installation Notes

Belt replacement should be performed by a qualified technician following equipment lockout/tagout procedures before removing any drive guards. Loosen the drive motor mount to relieve tension before removing the old belt; never pry a belt over sheave flanges. Inspect sheaves for wear, misalignment, and debris before installing the new belt, then re-tension according to the equipment manufacturer's deflection specifications. Verify sheave alignment with a straightedge or laser tool before returning the unit to service.
