Tensioner Assembly

The tensioner assembly is a key component of the automotive engine transmission system, mainly used to guide and tension the timing belt or timing chain, ensuring it is always at optimal tension to prevent slippage, skipping teeth, or missing teeth, thereby ensuring the accuracy of the engine valve timing.

The spring plays the role of the core power source in the tensioner assembly. The design parameters of the spring (stiffness, preloading force, fatigue life) directly determine the performance and lifespan of the tensioner assembly.The spring in the tension assembly is usually a high-stress, high-fatigue-life precision spring, with extremely high requirements for wire diameter accuracy, material uniformity, and heat treatment process — this is precisely where the competitiveness of an excellent spring factory lies.
