Continental Contitech 20039618 Bx Cogged V-belt BX112

Product Description

The CONTINENTAL CONTITECH 20039618 is a BX-section cogged V-belt engineered for power transmission applications across HVAC, industrial, and mechanical drive systems. Built with Fiber-Reinforced Vytracord construction, this Torque-Flex belt delivers reliable torque transfer in demanding environments. It measures 115 inches in outside length with an internal length of 113.80 inches. The cogged profile reduces bending resistance, improves flexibility around smaller sheave diameters, and runs cooler than standard V-belts under load. The oil-resistant compound adds durability in equipment bays where fluid exposure is common. Licensed HVAC technicians and mechanical service professionals are the primary installers for this belt type.

This belt is suited for residential and light commercial HVAC blower drives, refrigeration unit drives, and general industrial power transmission applications where a BX-section belt is specified. It performs across a wide temperature range, making it appropriate for both cold-storage refrigeration equipment and high-ambient mechanical rooms. The belt carries the manufacturer designation BX112, which is the standard cross-reference number used when ordering or specifying this size in the field.

Key Features

• Cogged profile reduces bending resistance and heat buildup during operation
• Fiber-Reinforced Vytracord construction for high tensile strength and dimensional stability
• Oil-resistant compound suitable for environments with incidental fluid exposure
• Torque-Flex design improves performance on smaller-diameter sheaves
• Wide operating temperature range from -40 degrees C to 60 degrees C
• BX112 belt number provides direct cross-reference for field replacement ordering

Compatibility

Designed as a direct replacement for BX112-designated V-belt applications requiring a BX-section cogged belt with 115 inches outside length and 113.80 inches internal length.

Installation Notes

Installation should be performed by a qualified HVAC technician or mechanical service professional. Always de-energize and lock out the equipment before removing or installing drive belts. Never pry a belt onto a sheave using a screwdriver or bar, as this can damage the belt cords and reduce service life. Verify sheave alignment and proper belt tension according to the equipment manufacturer specifications before returning the system to service.
