In automotive engineering, every component plays a key role in ensuring smooth operation of a vehicle. Automotive tensioners are key parts that keep belts at the right tension in a vehicle's power system. They enhance the efficiency and lifespan of a vehicle's components.

Reasons behind the growing demand for automotive tensioners

These key automotive components help prevent slippage and ensure efficient power transfer to various vehicle parts. They extend the lifespan of the belt of the vehicle and minimize the need for frequent repairs by reducing strain and wear. Proper tension enhances overall vehicle performance by ensuring the smooth operation of essential systems like the alternator, air conditioning, and power steering. In addition, a well-maintained tensioner pulley improves safety by preventing belt failures that could compromise important functions. Automotive tensioners help lower maintenance costs over time by reducing premature wear and the risk of component failures.

Popular automotive tensioners widely used in modern vehicles

The automotive tensioner industry has witnessed prominent growth due to the increasing development of innovative types of automotive components. Auto tensioner pulleys are spring-loaded devices that automatically adjust to maintain the correct tension on belts as they wear and stretch over time. They prevent belt slippage, reduce wear and tear, and improve vehicle performance by ensuring efficient power transfer to components like the alternator and air conditioning compressor.

On the other hand, friction damped belt tensioners, developed by companies like Mubea, are used in conventional and hybrid applications. They optimize belt forces, reduce friction, and lower CO2 emissions, making them suitable for modern belt drive systems. These tensioners enhance durability and efficiency, supporting both mild and full hybrid setups while minimizing installation space requirements and improving overall system reliability.

Moreover, hydraulic auto tensioner bearings utilize hydraulic dampers to automatically adjust belt tension, enhancing reliability in timing and auxiliary belt systems. These tensioners are equipped with sealed deep groove ball bearings, ensuring durability and resistance to environmental factors. The hydraulic system provides smooth tension adjustments, reducing wear on belts and other components, while the sealed bearings protect against contamination and extend the lifespan of the tensioner.

Cloyes and ATI joined forces to advance engine component solutions

In February 2024, Cloyes Gear & Products, Inc., a global leader in timing drive systems for the automotive aftermarket, acquired Automotive Tensioners Incorporated, a Texas-based supplier of front-end accessory drive pulleys and tensioners. This acquisition represents a significant step taken by Cloyes to enhance its platform and strengthen its value proposition for repair shops. In addition, the firm aims to expand its product offerings and market presence by utilizing ATI’s expertise. According to, John Hanighen, President and CEO of Cloyes, through this agreement, the company has valued ATI's proficiency in developing and sourcing high-quality engine products that meet the demands of modern vehicles throughout its six-year collaboration.

The essence

Automotive tensioners have emerged as a key component in maintaining optimal belt tension, ensuring efficient power transfer, and enhancing the overall performance and longevity of vehicle components. Moreover, increase in the demand for emission-free and fuel-efficient automobiles is likely to increase the development of advanced automotive tensioners in the coming years.
