Description
A BX37 is an industry-standard B-section raw-edge cogged V-belt designed for high-horsepower, heavy-duty industrial, HVAC, and agricultural power transmission applications. The "BX" profile indicates a heavy-duty classical cogged cross-section, while "37" represents its nominal inside length in inches. It is manufactured by premium industrial brands like Gates, Dayco, Bando, and Continental.
Key Specifications
- Industry Belt Number: BX37
- Inside Circumference: 37 inches (940 mm)
- Outside Circumference: 40 inches (1,016 mm)
- Top Width: 21/32 inch (17 mm)
- Thickness: 7/16 inch (11 mm)
- Material: EPDM rubber compound reinforced with high-strength tensile cords
Design & Performance
- Raw-Edge Molded Notches: The precision-molded cogs provide excellent flexibility, allowing the belt to easily wrap around smaller diameter pulleys while dramatically reducing bending stress and internal heat buildup.
- Higher Horsepower Ratings: Delivers significantly higher horsepower capacity than standard wrapped B-section belts (like a conventional B37) due to its superior wedge grip and robust internal cord construction.
- Severe Environmental Resistance: Engineered from premium industrial-grade EPDM rubber to resist hardening, oil absorption, ozone damage, and continuous high-temperature operating conditions up to 250°F (121°C).
- Static Dissipative: Meets strict ARPM/ISO standards for static conductivity, ensuring safe operation in environments where static sparks must be prevented.
Common Applications
- Industrial & HVAC: Air compressors, heavy-duty ventilation blowers, vacuum pumps, and commercial air handling units.
- Agricultural Machinery: Power take-off (PTO) drives, grain handling augers, harvesting equipment, and tractor sub-assemblies.
- Outdoor Power Equipment: Heavy-duty commercial lawn mowers, wood chippers, and industrial generators.
