fan belt and timing belt

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.
