Continental Contitech 20039646 BX300 Torque-flex V-belt

Product Description

The CONTINENTAL CONTITECH 20039646 is a BX-section Torque-Flex V-belt designed for demanding drive applications where standard belts fall short. Manufactured with Fiber Reinforced Vytracord construction, this belt delivers high tensile strength and resistance to bending fatigue. It carries a belt number designation of BX300, with a 301.5-inch outside length and a 300.30-inch internal length. The cogged BX profile reduces heat buildup and improves flexibility, making it well suited for smaller-diameter sheaves. Technicians and maintenance professionals in HVAC, industrial, and agricultural settings install this belt as a direct replacement or new-drive component on equipment requiring a BX-section drive belt.

This belt is used in a wide range of residential and commercial applications including HVAC blower drives, compressor drives, pump drives, and general industrial power transmission setups. The BX section is a cogged raw-edge belt that fits standard BX-profile sheaves and is commonly specified on equipment where drive efficiency and flex life are priorities. It is sold individually and is appropriate for both original equipment installations and field replacement service calls.

Key Features

• BX-section cogged profile reduces bending stress and heat on small-diameter sheaves
• Fiber Reinforced Vytracord construction provides high tensile load capacity and durability
• Torque-Flex style design improves flexibility and power transmission efficiency
• 301.5-inch outside length with 300.30-inch internal length for precise drive sizing
• Sold as a single unit with no minimum order quantity above one

Compatibility

Designed as an OEM-style replacement or new-installation BX-section V-belt for equipment specifying a BX300 belt on standard BX-profile sheave drives in HVAC, industrial, and general power transmission applications.

Installation Notes

Belt installation and replacement should be performed by a qualified technician following all relevant lockout/tagout procedures before removing guards or handling drive components. Never pry or roll a belt onto a sheave using a tool that can nick or cut the belt material. Adjust drive tension per the equipment manufacturer's deflection specification after installation and recheck after the first few hours of operation. Inspect sheave grooves for wear before installing a new belt, as worn grooves accelerate belt degradation.
