Series 40 SCU

Series 40 SCU

Transporting, loading, hauling, dumping—big tasks require big, powerful vehicles with the steering ability to match. The Series 40 Steering Control Unit (SCU) from Eaton makes getting more responsive, reliable steering in a small, compact package more cost effective than ever before. Featuring integrated valves—both symmetrical and progressive for uniform, efficient steering—a high capacity Eaton Gerotor assembly and two available patented designs (balanced architecture and wide angle), the Series 40 SCU is the go-to solution for both articulated- and fixed-frame vehicles.
  • Patented balanced architecture and wide angle designs increase reliability and reduce system costs
  • Optional pilot pressure port can be used for applying pressure to priority valve as well as for diagnostics
  • Symmetrical valving increases balance for precise servo response and uniform steering action, as well as progressive valving to reduce operating costs
  • Thicker sleeve design provides stability, especially under pressure- and thermal-transient conditions.
  • Eaton Q-Amp® technology maximizes steering control
  • High-capacity Gerotor provides ample fluid displacement
  • Integrated valves and load-sensing capabilities and match performance to load requirements
