Description
An AX69 is an industry-standard A-section raw-edge cogged V-belt engineered for heavy-duty industrial, agricultural, and commercial power transmission. The "AX" designator identifies its classical cogged cross-section profile, while "69" signifies its nominal internal circumference length in inches. Premium implementations of this model include options like the Timken Gold Label series.
Key Specifications
- Industry Belt Number: AX69
- Inside Circumference: 69 inches (1,753 mm)
- Outside Circumference: 71 inches (1,803 mm)
- Top Width: 1/2 inch (13 mm)
- Thickness: 5/16 inch (8 mm)
- Material: Premium EPDM rubber compound embedded with heavy-duty polyester tensile cords
Design & Performance
- Precision-Molded Notches: The raw-edge cogged profile reduces bending stress as the belt wraps around the pulley, allowing it to easily handle smaller diameter sheaves while minimizing internal heat buildup.
- High Efficiency: Delivers superior wedging grip and runs significantly cooler than wrapped standard A-section belts, helping to reduce energy loss by up to 3% over standard profiles.
- Robust Environmental Durability: Formulated with industrial-grade rubber compounds that provide strict resistance to core breakdown, oil exposure, ozone degradation, and harsh temperature variations up to 250°F (121°C).
- Static Dissipative: Meets standard ARPM/ISO parameters for static conductivity, ensuring safe mechanical operation in demanding or dust-prone environments.
Common Applications
- HVAC Systems: Industrial air handling units, commercial exhaust blowers, and supply fans.
- Industrial & Workshop Machinery: Tool lathes, milling machine drives, automated rollers, and heavy-duty air compressors.
- Agricultural Equipment: General power take-off (PTO) sub-assemblies, harvest sorting tables, grain handling machinery, and tractor belt loops.
