Comparison chart of Hydraulic system and Electric mechanical system
Comparison chart of Hydraulic system and Electric mechanical system
| Item | Hydraulic | Electric mechanical | |
|---|---|---|---|
| 1 | Life time | ・Long life（drive in lubricant） ・Maintenance free |
・Short life（degradation by abrasion of sliding area） ・Need to do maintenance |
| 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 |
