toothed rubber drive belts

Another remarkable feature of HNBR is its low compression set, which means that it resists permanent deformation when subjected to compressive loads. This is essential for timing belts, as they need to maintain their shape and tension over time to ensure proper functioning of the engine's timing system. With lower compression set values, HNBR timing belts can maintain their performance characteristics longer than those made from conventional materials.

Regular inspection of the serpentine belt is essential. Mechanics often recommend checking for visible signs of wear, including cracks, fraying, or glazing on the belt surface. These indicators can signal that it's time for a replacement. Furthermore, the lifespan of a serpentine belt can vary greatly depending on the make and model of the vehicle, driving conditions, and maintenance practices. Generally, it is advised to inspect the belt every 30,000 to 50,000 miles.
