This table compares the advantages and disadvantages of electric cylinders (electric actuators) and
pneumatic cylinders (pneumatic actuators), providing a comprehensive comparison across multiple
dimensions:
Comparison Dimensions Electric Cylinders Pneumatic Cylinders
Precision Control High precision (down to micron level), Lower precision (depends on mechanical structure,
supports closed-loop control susceptible to air pressure fluctuations)
Speed Control Precise speed adjustment, supports variable speed motion Speed is limited by air pressure, with a limited adjustment range
Maintenance Cost Low maintenance (no air source required, simple structure) Requires regular maintenance (such as lubrication and seal replacement)
Energy Efficiency High efficiency (direct conversion to electricity, no energy loss) Low efficiency (energy loss in compressed air generation and transmission)
Environmental Adaptability Sensitive to temperature and humidity, High temperature resistance, explosion-proof,
requiring dust and water-resistant design and pollution-resistant
Load Capacity Small to medium loads (large loads require a larger motor) High load capacity (air pressure can easily move heavy objects)
Noise Level Low noise (motor operates quietly) High noise (exhaust noise and mechanical shock)
Installation complexity Requires electrical wiring, but compact design Requires air supply piping, flexible installation, but complex piping.
