Series 20 SCU

Series 20 SCU

Ideal for both rigid frame and articulated vehicles, Eaton’s Series 20 Steering Control Unit (SCU) is the perfect choice for smooth, precision steering in trucks, transporters, tractors and more. With a high capacity Gerotor, a thicker sleeve design, and proven Eaton technologies like Q-Amp®, Wide Angle and VersaSteer, these compact SCUs give operators the low-effort steering feel they want and engineers the reduced system costs and space requirements they need.
