The most common material used in timing belts is various types of rubber. Synthetic rubber, such as neoprene, is often preferred due to its superior resistance to heat and wear compared to natural rubber. The rubber provides flexibility, allowing the belt to bend around pulleys without cracking. This elasticity also contributes to a quiet operation, reducing engine noise. However, rubber's susceptibility to degradation from oil, heat, and ozone exposure necessitates the incorporation of additives and reinforcements.

A tensioner belt pulley is part of the vehicle's serpentine belt system, which drives multiple accessories such as the alternator, water pump, power steering pump, and air conditioning compressor. The tensioner itself is a spring-loaded or hydraulic device that maintains tension on the serpentine belt, ensuring it remains tight enough to function properly without slipping or breaking. The pulley, which is an integral part of this mechanism, assists in guiding the belt around the engine's various pulleys while providing the necessary tension.
