Benefits of Replacing Hydraulic Cylinders with Electric Actuators
Improve process control, increase efficiency, eliminate leaks, & get many other advantages by adopting electric actuator systems
1: EVALUATE POTENTIAL BENEFITS
Flexible Operation: would it be helpful to quickly and easily be able to adjust stroke lengths, forces, speed of movements?
Precise Movement: would it be helpful to improve your precision…so that every time you make a move you get exactly the same result?
Data Collection: would it be helpful to collect data from the motor and actuator so you could record how far the actuator moved, how much force was exerted and what speeds the actuator moved at?
Leaks and Environmental Concerns: would it be helpful to eliminate the potential for hydraulic fluid leaks in the manufacturing environment to improve safety and better insure product quality?
Maintenance: would it be helpful if you had a system with fewer moving parts, almost no on-going maintenance requirements and doesn’t contain pressurized oil?
Ambient Temperature: would it be helpful if you got the exact same performance regardless if the ambient temperature was below freezing or the hottest day of the summer?
Other factors: Utility costs, Noise, Shock loads
2. ACCURATELY SIZE ACTUATOR
Converting a hydraulic cylinder to an electric actuator system requires understanding three key variables: force, motion profile and electric actuator technology.
A costly mistake when converting to an electric system is oversizing the actuator.
Learn valuable tips for sizing and selecting high force actuators – from 50 lbf to 50,000 lbf (0.2 kN to 222.4 kN).

Some Sizing Tips:
- Identify application loads and forces including tooling, reactive forces, press forces, drag, etc….
- Motion profiles and cycle rates
- Be as accurate as possible
- What is important: Speed, cycle time or both
- Don’t forget dwells!
