Car Auxiliary Components: belts and pulleys

The OP auxiliary components are made with materials and processes that comply with OE standards, such as for example ADC12 aluminium, used in the original equipment and CNC turning which guarantees greater precision and control of tolerances and concentricity.

To guarantee the high quality and performance standards of the original OES spare parts, the OP auxiliary components are subjected to rigorous durability tests in which the components maintain unchanged performance after long test cycles, even in the presence of extreme temperatures they do not report damage or alterations of the materials; as well as salt spray tests to test the high resistance to corrosion of the components.

The OP range of auxiliary components for cars is constantly updated, covering around 90% of the European car fleet, including all vehicle generations. Among the most popular applications are Peugeot 208, Volkswagen Golf, Dacia Sandero, Renault Clio, Toyota Yaris, Fiat 500, Citroen C3, Hyundai Tucson, Toyota Corolla, Mercedes A-Class, BMW Series and many more.

  • Tensioners: keep constant tension on the auxiliary belt, avoiding tension overload and slippage that can affect belt performances and cause premature wear.
  • Damper Pulley: Damper Pulley, commonly known as a crankshaft pulley, transmits rotation from the crankshaft to the car auxiliary components (power steering pump, climate control compressor, alternator, etc.) to which it is connected by one or more Poly-V belts, and absorbs vibrations.
  • Freewheel alternator pulley: double bearing with cylindrical side rollers: It offers better radial load distribution, while maintaining the correct positioning of the auxiliary belt.
  • Poly-V Belt: Auxiliary Belt structure in polyester fibers and EPDM Rubber with long fibers, increases grip and resistance to slipping. The Aramid Fiber cover improves mechanical resistance and gives extra strength against wear, heat, oils and water.


The Auxiliary Components category of OP offers a wide range of components that ensure reliable vehicle performance.
Choosing OP products means offering your customers the best to ensure maximum satisfaction.
