This is a wearing part: the plastic wears out over time. force to slide in the variator, and they should be replaced when they have a flat spot which interferes with proper operation.

Operation and importance for vehicle performance

The variator is equipped with a belt and two cheeks: one fixed and one mobile, between which the rollers are placed. Depending on the engine speed, the force centrifugal pushes the rollers outwards. This has the effect of bringing the cheeks closer to each other and modifying the passage diameter of the belt. Speed ​​variations are thus transmitted fluidly, offering smooth driving and optimal performance.

Thus, unsuitable, worn or seized rollers can cause significant problems, such as loss of speed, insufficient acceleration or even damage to your engine.

The different types

There are a variety of variator pulleys on the market, suitable for different vehicle brands, different engine powers and various driver needs.
