Belt Tensioner Pulley 11287649371 For BMW F49 F52

BMW's tensioner is an important component in the engine timing system, also known as tensioner or tensioner roller. It has the following characteristics:

1. Automatic tensioning: BMW tensioner adopts automatic tensioning design, and the tension of timing chain or belt can be automatically adjusted through internal hydraulic or spring device. This design can ensure that the timing chain or belt always keeps proper tension, so as to reduce the risk of looseness and tooth jumping and improve the reliability and performance of the engine.

2. High durability: BMW tensioner is made of high-strength materials, such as steel or aluminum alloy, to ensure its excellent durability and reliability in high-temperature and high-pressure working environment. They are precisely processed and heat treated to provide excellent wear and corrosion resistance, thus prolonging the service life of the tensioner.

3. Noise and vibration control: BMW tensioner adopts advanced damping and noise control technology to reduce the noise and vibration generated by timing chain or belt during operation. They are usually equipped with damping pads or devices, which can effectively reduce the impact and vibration of chains or belts and provide more stable and quiet engine operation.

4. Accurate adjustment: BMW tensioner has an accurate adjustment mechanism, which can automatically adjust the tension of chain or belt according to the change of engine load and speed. This precise adjustment can ensure the accuracy and stability of the timing system and provide the best engine performance and fuel economy.

In a word, BMW's tensioner has the characteristics of automatic tensioning, high durability, noise and vibration control and accurate adjustment. They are the key components in the engine timing system, which can improve the reliability, performance and fuel economy of the engine by ensuring the proper tension of the chain or belt.
