Comparison chart of Hydraulic system and Electric mechanical system
| Item | Hydraulic | Electric mechanical | |
|---|---|---|---|
| 1 | Life time |
|
|
| 2 | Noise / Vibration | Reduce noise, pulsation and vibration | Big noise and vibration |
| 3 | Shockless | Easy to improve | Hard to improve(costly) |
| 4 | Speed | It is possible to improve to the speedy motion(over 20mm/sec.) | It provides medium or low speed(Max: 5-10mm/sec.) |
| 5 | Load | Easy to handle high load | It can handle only low or medium load |
| 6 | Energy saving | It can provide energy saving by "down by own weight" or "spring return"(It doesn't need Motor driving) | It needs Motor driving constantly during operation |
| 7 | Space design | It can set up the cylinder unit with narrow space because of separation of pump unit and cylinder. The pump unit can be set on a extra space -> It brings enough lowest position |
The actuator unit needs wide space because of one-piece body of actuator and motor |
