ribbed belt

A serpentine belt is a long, flat belt made from durable rubber that winds around various pulleys within the engine compartment. It is characterized by its unique design, which allows it to loop around multiple components, thus minimizing the number of belts needed to operate essential systems. The term serpentine derives from its winding or serpentine shape, which is visually distinct compared to the older setup of multiple V-belts used in many vehicles prior to the late 20th century.

A timing belt is a looped belt made of reinforced rubber or urethane with teeth that mesh perfectly with the teeth on the gears of the pulleys. The primary function of the timing belt is to synchronize the rotation of the crankshaft and camshaft in an internal combustion engine, ensuring that the engine's valves open and close in time with the movement of the pistons. This synchronization is critical for optimal engine performance and efficiency, preventing any potential interference that could lead to engine damage.

Poly-V TB2 belts are flat belts characterized by several longitudinal ribs. These ribs provide a larger surface area for contact, which allows for improved traction and reduces slip compared to traditional V-belts. The TB2 designation typically refers to a specific design variation or dimension suitable for certain pulley systems. These belts are utilized in a wide range of applications, from automotive engines to industrial machinery, where they transfer power efficiently and effectively.
