tensioner fan belt

A PU V belt is a type of drive belt made from polyurethane. This material provides several advantages over traditional rubber belts, including higher durability, enhanced resistance to wear and tear, and the ability to handle a broader range of operating temperatures. PU V belts typically have a trapezoidal cross-section, which allows for better grip and efficiency in transferring power from the engine’s crankshaft to other components, such as the air conditioning compressor.

To enhance the strength and durability of timing belts, manufacturers often incorporate reinforcement materials such as fiberglass or aramid fibers (e.g., Kevlar). These reinforcements prevent elongation and ensure that the belt maintains its shape under tension. Fiberglass is commonly used for its high tensile strength and ease of manufacturing, while aramid fibers are known for their impressive heat resistance and toughness. Using these materials in timing belts results in better performance under high-load conditions, reducing the likelihood of belt failure.
