Continental Contitech 20039640 Cogged V-belt Bx 198 in

Product Description

The CONTINENTAL CONTITECH 20039640 is a BX-section cogged V-belt designed for industrial and HVAC drive applications requiring reliable power transmission. Built with Fiber-Reinforced Vytracord construction, this belt delivers high tensile strength and resistance to flex fatigue. The cogged profile reduces bending stress and heat buildup, making it well-suited for smaller-diameter sheaves and variable-speed drives. It carries an outside length of 198 inches and an internal length of 196.80 inches, corresponding to belt designation BX195. The oil-resistant compound adds durability in environments where incidental fluid exposure is a factor.

This belt fits standard BX-section sheave configurations found in commercial HVAC air handlers, industrial fan drives, pump drives, and general power transmission equipment. It is commonly installed by HVAC technicians, millwrights, and mechanical contractors during scheduled belt replacements or drive system upgrades. The Torque-Flex style designation indicates suitability for drives with shock loading or pulsating torque demands. Rated for operation between -40 degrees C and 60 degrees C, it performs across a broad range of ambient conditions.

Key Features

• BX-section cogged profile reduces bending resistance on small-diameter sheaves
• Fiber-Reinforced Vytracord construction provides high tensile strength and flex-fatigue resistance
• Oil-resistant compound for durability in environments with incidental fluid exposure
• Torque-Flex style handles shock loading and pulsating torque drive applications
• Wide operating temperature range: -40 degrees C minimum to 60 degrees C maximum
• Outside length 198 inches, internal length 196.80 inches (belt number BX195)

Compatibility

Designed as an OEM-style replacement for BX-section V-belt drive systems. Belt designation BX195 fits any sheave configuration specifying a standard BX195 cogged V-belt.

Installation Notes

Installation should be performed by a qualified HVAC technician or mechanical contractor. De-energize and lock out the drive system before removing the old belt or installing the new one. Never pry or force a belt over sheave flanges; always move the drive motor to the slack position to allow proper seating. After installation, verify alignment and tension per the equipment manufacturer specifications before returning the system to service.
