Browning BX68 Belt

The Browning BX68 Gripnotch Belt is a heavy-duty classical cogged V-belt engineered for demanding HVACR applications requiring high torque transmission and superior heat dissipation. This EPDM belt features a 71-inch outside diameter and a 69.8-inch pitch length, designed specifically for a BX-section groove. Unlike standard wrapped belts, the Gripnotch construction utilizes precision-molded cogs to increase flexibility and surface area, allowing for efficient operation on smaller pulley diameters while maintaining a 98% efficiency rating. The raw-edge sidewalls facilitate aggressive gripping contact to eliminate slippage and reduce vibration in high-static pressure blower assemblies.

Built for industrial durability, the Browning BX68 utilizes high-tensile polyester cords that resist elongation and maintain tension under fluctuating loads. Its advanced EPDM rubber compound provides a wide operating temperature range from -70°F to 250°F, ensuring reliability in rooftop units and extreme mechanical rooms. This belt meets ARPM IP-20 standards for oil and chemical resistance and is static dissipating per ARPM IP-3-3, making it a reliable choice for technical professionals seeking to optimize HVAC drive maintenance and system performance.

Key Benefits

• Superior heat dissipation via Gripnotch cogged design, extending service life in high-temperature environments.
• High energy efficiency rating of 98%, reducing drive losses compared to standard wrapped belts.
• Code 1 Match system ensures tighter tolerances than RMA standards for easy belt matching in multi-groove drives.
• Advanced EPDM construction offers resistance to oil, chemicals, and extreme thermal cycling.
• Raw-edge sidewalls maximize grip and minimize parasitic vibration for quieter mechanical operation.

Common Questions

What are the exact dimensions of the BX68 belt?
The Browning BX68 has a nominal outside length of 71 inches, a pitch length of 69.8 inches, and a top width of 21/32 inches.

Is the BX68 compatible with standard BX sheaves?
Yes, as a BX-section industrial V-belt, it is designed to fit standard BX sheaves and can often replace a standard B-section wrapped belt to provide higher horsepower capacity.

How does EPDM benefit HVACR installations?
EPDM is highly resistant to ozone, weather, and heat (up to 250°F), preventing the premature cracking and hardening often seen with traditional chloroprene belts in rooftop air handlers.
