Pneumatic Cylinder & Electric Actuator
Normally, Pneumatic Cylinder and Electric Actuator are categorize as two completely different items of automation products. Although Electric Actuator is applied in more and more pneumatic area under the improvement of electrification, Cylinder is still necessary for all applications. Here introduce the advantages of pneumatic cylinder and electric actuator, including Technical, Cost, Energy Efficiency, Applications and Marketing.

Technical Performance
Pneumatic Cylinder is generally known as a kind of product featured with reliably-working, easy-operation, maintenance-free in harsh environment ranges, compared to electric actuator. Good at reciprocating linear motion, especially suitable for most of transmission requirements in industrial automation, like linear handling, and adjusting the one-way throttle valve installed on both sides can easily control speeds, Pneumatic Cylinder is best and convenience choice for customer in point positioning applications.
Electric Actuator is suitable for rotation and swing system, whose advantage lies in quick-response and well-control to speed, position and torque in the industrial field require high-precision, precise multi-point positioning, But Electric Actuator is too complex to make linear movement, as it needs to be through the tooth belt or screw and other mechanical devices for transmission conversion, and its working environment and its operation and maintenance by qualified personnel, so the next best choice is Pneumatic Cylinder.
Advantage
-Electric Actuator
1).Compact and simple structure
2).Easier and lower demand to drive
3).High reliability, no air leakage
4).No need to install and maintain to pneumatic pipe
5).Stand-by or hold on without power consumption
6).Lower voice during operation
7).Better in precise point positioning (PPP)
-Pneumatic Cylinder
1).Big load, better in high torque output applications
2).Quick-respond
3).Better adaptability to the working environment, especially in flammable, explosive, dust, strong magnetic, radiation and vibration and other harsh working environment, compared to hydraulic, electronic, electrical controls.
4).No damage when Travel obstruction or stem stuck

 | SC Series Cylinder SC Cylinder, referred to as actuators, are devices that use compressed air as the source of gas and converts the pressure energy of the gas into mechanical energy with the form of rotary or linear motion. SC Series pneumatic cylinder has two types Tie-rod type and X type, normal bore size from 32mm to 200mm, bigger size from 250mm to 600mm can also be provided. This series is popular selling in the Asia

Energy efficiency comparison
A study says Pneumatic Cylinder is better for energy saving in the condition of short reciprocating movement period (>1min), meanwhile, Electric Actuator is usually lower than that of the pneumatic cylinder in less period (<1min).
Electric Actuator is certainly in good and high efficiency for automation, but it is not good choice when considering the efficiency decline and the power consumption of the controller in the reciprocating linear motion.
The aim of the specific comparison between Pneumatic Cylinder and Electric Actuator depends on the actual working conditions, such as the installation direction, the reciprocating movement period and the load rate.
Comparison of applications
With harsh environments, like dust, grease, water or cleaners, Pneumatic Cylinder is more adaptable to achieve the automation simple driving functions, feature with easy to install, long service time and lower cost.
Although automation systems are getting more complex and more precise nowadays, Pneumatic Cylinder is better for pneumatic automation system from the perspective of technology and cost. Pneumatic Cylinder can simply make fast linear movement with simple structure and convenient maintenance under a variety of harsh working environments, such as explosion-proof requirements, dust or wet conditions.
Meanwhile, Electric actuators are mainly used for the system needs precise controls in different sizes of machining, like mult-ipoint positioning control, precise control or synchronous tracking speed and torque
In a result, Pneumatic Cylinder is more suitable for simple motion control, and the Electric Actuator is more used for precision motion controls.
