A synchronous belt is a toothed belt that operates on the basis of positive engagement between the belt and a series of pulleys. Unlike traditional V-belts that rely on friction to transmit power, synchronous belts have teeth that fit into corresponding grooves on the pulleys. This unique design provides a distinct advantage in scenarios where precise timing is critical. By maintaining exact synchronization between connected components, these belts ensure smooth and efficient operation in various applications.

The AT5 timing belt is a type of synchronous belt characterized by its trapezoidal tooth profile. The A stands for the design category, T refers to the belt being a timing or synchronous belt, and 5 denotes the pitch of the teeth, which is 5mm. This specific design allows for precise synchronization between the crankshaft and camshaft in engines, ensuring that the valves open and close at the correct times relative to the movement of the pistons.
