• Series: SK (Standard V-Belt)
• Length: 1257 mm (measured as the inside circumference of the belt)
• Width: 12.70 mm (W), which refers to the width of the belt.
• Height: 10 mm (H), which refers to the height or thickness of the belt.

Key Features:

• Material: Typically made of high-quality rubber compounds, often reinforced with fibers to enhance the belt’s strength and durability.
• Shape: The “SPA” designation indicates a specific cross-section size designed for efficient power transmission.
• Applications: Ideal for use in various industrial and automotive applications that require reliable power transmission.

Like the OPTIBELT SPA 1282, the OPTIBELT SPA 1257 is commonly used in mechanical systems that need a dependable power transfer, such as in machinery, vehicles, or agricultural equipment. The length of the belt (1257 mm) differs from the SPA 1282, but the width and height remain the same, making them compatible with different applications depending on the system’s specific requirements.
