variable speed belt sizes

In automotive applications, timing belts are vital for maintaining engine performance. Most modern vehicles use timing belts instead of chains due to their lighter weight and noise-reducing properties. The belts are often made from high-tensile materials that have excellent wear resistance, enhancing their longevity. Depending on the vehicle and usage, a timing belt may require replacement every 60,000 to 100,000 miles, which makes regular maintenance crucial.

A timing belt is a reinforced rubber band with teeth that link the crankshaft to the camshaft, ensuring synchronized rotation. Meanwhile, a timing chain serves a similar function but is made of metal links, providing a more durable solution. Both components are responsible for the timing of the engine's valves, which must be in sync with the movement of the pistons. The rotation of these components is influenced by the engine's operation, and any delay or dissonance can lead to catastrophic engine failure.
