Electro-Hydraulic Drive Actuator (EH-D)

The EH-D is a revolutionary electro-hydraulic, linear solution.

Designed and manufactured by German company Böhner-EH, the Electro-Hydrostatic Drive combines the force capabilities of a hydraulic cylinder with the efficiency and programmability of an electric actuator, all within a compact, sealed for life capsule design.

No Pipes, No Cooling, No Power Pack, No Wearing Parts... Say Yes to Maintenance free Actuation!
