Browning BX67 Belt

The Browning BX67 Gripnotch Belt is a heavy-duty, cogged V-belt engineered for demanding HVACR and industrial drive systems. This 70-inch outside diameter belt features a standard BX section profile with a 21/32" top width and 13/32" thickness, making it a drop-in replacement for classical wrapped belts that require higher horsepower ratings or smaller sheave diameters. Constructed from high-grade EPDM synthetic rubber, the BX67 provides a broad operating temperature range from -60°F to 250°F, ensuring reliable performance in extreme rooftop unit (RTU) environments and heat-sensitive mechanical rooms.

The raw-edge sidewalls are precision-machined to improve pulley contact, significantly reducing vibration and slippage compared to traditional envelope-style belts. By utilizing precision-molded cogs, the belt achieves superior flexibility and increased surface area for heat dissipation, which prevents premature cord degradation. Integrated high-tensile nylon cords provide excellent resistance to elongation and shock loading, maintaining consistent 68.8-inch pitch length tension under heavy start-up torques. This cogged V-belt is specifically optimized for high-speed fans, blowers, and compressor drives where efficiency and longitudinal flexibility are critical for system longevity.

• Maximum Flexibility: Molded notches allow for operation on smaller diameter sheaves without the cracking or overheating common in wrapped belts.
• Enhanced Grip: Raw-edge construction increases the coefficient of friction, reducing energy loss and unwanted noise.
• Temperature Resilience: EPDM formulation resists hardening and glazing in high-ambient HVAC applications up to 250°F.
• Code 1 Matching: Manufactured to Browning’s "Code 1" tolerance standards, allowing for easy multi-belt drive matching without measuring individual belts.
• Chemical Resistance: Synthetic rubber compound provides inherent resistance to oil, heat, and environmental contaminants.

Is the BX67 compatible with standard B-section pulleys?
Yes, the BX67 is designed to run in standard B-series sheaves. The cogged "X" profile offers a technical upgrade over the B67 wrapped belt by providing higher horsepower capacity and better flexibility around small pulleys.

How does this belt handle high-start torque applications?
The flex-bonded nylon tensile cords are specifically treated to absorb bending stress and shock loads, ensuring the belt maintains its 68.8" pitch length without excessive stretching during motor startup.

Can I mix this with a different brand of BX67 on a multi-groove drive?
For optimal performance and even load distribution, it is best practice to replace all belts on a drive at once. Mixing the Browning BX67 with other brands or different wear levels can cause uneven tension and premature failure of the new belt.
