A tensioner pulley is an essential part of a timing belt system and is responsible for maintaining the tension and providing support for the belt. It is usually mounted on the engine block and is connected to the belt through the tensioner rod. The pulley consists of a metal core, usually aluminum or steel, surrounded by a rubber coating. The metal core is designed to be durable, while the rubber coating helps to reduce vibration and noise. The tensioner pulley can be used in a variety of applications, such as automotive engines, industrial machinery, and agricultural equipment.
