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 |
