EHA (Electro-Hydraulic Actuation) Advantages

The EHA's efficient method of converting power leads to a smaller cost effective package. The EHA design holds a load without an external brake using simple valves.

More Force with Less Space

Force equals Area x PSI

On-board Pressure Sensor Provides Force Feedback

Exponential force with small increases in cylinder size.
e.g. from 2.5" to 3" (20% inc) the force increases (44%)
