Continental Contitech 20039552 BX38 Cogged V-belt 41 in

Product Description

The CONTINENTAL CONTITECH 20039552 is a BX-section cogged V-belt designed for power transmission in HVAC, industrial, and mechanical drive applications. Built with Fiber-Reinforced Vytracord construction, this belt delivers consistent torque transfer under demanding conditions. The cogged profile reduces bending resistance, allowing the belt to run cooler and flex more efficiently around smaller sheaves. With a 41-inch outside length and an internal length of 39.80 inches, it carries the standard BX38 belt designation. The oil-resistant compound resists degradation from incidental fluid contact. HVAC technicians, mechanical contractors, and equipment service pros install this belt in blower and fan drive assemblies.

This belt is suited for residential and light commercial HVAC blower drives, refrigeration unit fan drives, and general industrial power transmission setups that specify a BX38 cross-section belt. The cogged Torque-Flex style allows operation across a wide temperature range, from -40 degrees C through 60 degrees C, making it appropriate for both outdoor and indoor mechanical systems where ambient temperature extremes are a factor. It replaces worn or failed BX38 belts on matching drive configurations.

Key Features

• BX-section cogged profile reduces bending resistance for cooler, more efficient operation
• Fiber-Reinforced Vytracord construction for consistent tensile strength and dimensional stability
• Oil-resistant compound resists degradation from incidental fluid exposure
• Wide operating temperature range: -40 degrees C to 60 degrees C
• 41-inch outside length with 39.80-inch internal length matches BX38 industry designation
• Torque-Flex style suits variable and fixed-speed sheave drive applications

Compatibility

Designed as an OEM-style replacement for any drive system specifying a BX38 V-belt with a 41-inch outside length and BX cross-section sheaves.

Installation Notes

Belt replacement is typically performed by HVAC technicians or mechanical service technicians. Always disconnect and lock out power to the unit before removing the old belt or installing the new one. Proper belt tension is critical — under-tensioning causes slippage and heat buildup, while over-tensioning accelerates bearing and belt wear. Check sheave alignment and sheave groove condition before installing a new belt.
