· Hydraulic actuators are now capable of operating at higher pressure levels with reduced size, enabling more efficient use of hydraulic energy and compact system designs.
To better understand the advantages of hydraulic rotary actuators, it is essential to compare them with electric and pneumatic actuators:
Parameter | Hydraulic Actuators | Electric Actuators | Pneumatic Actuators |
Torque Output | High, suitable for heavy-duty applications | Moderate, limited by motor size | Low to moderate |
Compactness | Compact and high power-to-size ratio | Bulky, especially at high power | Compact but lower output |
Precision Control | High precision with smooth motion | Very high precision with advanced control | Limited precision |
Reliability in Harsh Environments | Excellent; performs well under high pressure and extreme temperatures | Limited; affected by heat and moisture | Limited durability in harsh conditions |
Cost | Moderate initial cost; low maintenance | High initial cost; maintenance-intensive | Low cost but less efficient |
Energy Efficiency | Highly efficient in heavy-load conditions | Highly efficient at low to moderate loads | Low efficiency due to air compression |
Conclusion: Hydraulic rotary actuators are unmatched in heavy-duty and high-torque applications, offering superior performance in extreme conditions where electric and pneumatic systems may fall short.
