Browning BX78 Belt
The Browning BX78 Gripnotch Belt is a heavy-duty, cogged V-belt engineered for high-torque HVACR and industrial drive systems. Featuring a BX section profile with a 21/32" top width and 13/32" thickness, this 81-inch outside diameter belt is constructed from precision-molded EPDM. This material allows for an expanded operating temperature range of -60°F to 250°F, ensuring performance in extreme environments where standard wrapped belts often fail. The notched design increases flexibility for smaller sheave diameters while maximizing surface area for heat dissipation, which significantly reduces internal heat buildup. Designed with a raw-edge sidewall, the BX78 provides a higher coefficient of friction for better grip and reduced slippage, resulting in higher horsepower ratings and improved mechanical efficiency for blowers, compressors, and pumps.
- Enhanced Flexibility: The Gripnotch profile allows the belt to bend more easily around pulleys, reducing stress and increasing drive efficiency.
- Maximum Grip: Raw-edge construction eliminates the covers found on standard belts, providing superior traction and reducing vibration.
- Code 1 Match: Part of the Browning matching system, ensuring that multiple belts on a single drive share the load equally without manual sorting.
- High-Tensile Strength: Synthetic tension members resist stretching and maintain consistent take-up over long-term operation.
- Chemical Resistance: EPDM construction offers natural resistance to oil, heat, and environmental hardening in demanding mechanical rooms.
Common Questions about the BX78 Belt
What are the exact dimensions of a BX78 belt?
The Browning BX78 has a nominal 81-inch outside diameter and a 78-inch datum length. It features a 21/32-inch top width and is approximately 13/32-inch thick.
Can I replace a standard B78 wrapped belt with a BX78?
Yes, the BX78 notched belt is a direct performance upgrade for a standard B78. It fits the same sheaves but offers better heat dissipation and a higher horsepower rating.
Why is the EPDM material important for HVAC service?
EPDM is more resistant to "checking" or cracking under high heat and maintains its flexibility in sub-zero temperatures, which is critical for rooftop units and industrial exhaust fans.
