Air is supplied from one side of the piston to generate air pressure. The air pressure pushes the piston to produce thrust to extend and return by spring or self weight.
Compared with the electric actuator, the cylinder can work reliably under harsh conditions, and the operation is simple, and the basic maintenance free can be realized. Cylinder is good at reciprocating linear motion, especially suitable for industrial automation in the most transmission requirements - workpiece linear handling. Moreover, only adjusting the one-way throttle valve installed on both sides of the cylinder can simply achieve stable speed control, which has become the biggest feature and advantage of the cylinder drive system. Therefore, for users without multi-point positioning requirements, most of them prefer to use cylinder from the perspective of convenience. At present, most of the applications of electric actuators in the industrial field require high-precision multi-point positioning, which is the result that it is difficult to achieve with the air cylinder.

The high elasticity of expanded ensures high energy absorption with low reaction force of foam filled marine fenders, which is essential to eliminate the risk of damage to the vessel hull.
Foam Filled Marine Fenders are entirely made of closed cell foam that guarantees unsinkability even in case of damage caused by breaking, rupturing or shearing when hitting rough vessel sides. Ever cell is separate and so water cannot migrate into the foam filled marine fenders.
The Ever-Guard foam filled marine fenders skin is constructed of tough and thick , which provides foam filled marine fenders with unsurpassed strength.  The skins is wrapped in a helix pattern and integrated within the skin itself. This advanced technique process makes the Ever-Guard foam filled marine fenders skin extremely durable to all weather, forces and marine conditions.
The polyurethane or is spray applied on foam filled marine fenders. This creates a high quality and homogeneous skin matrix combining extreme wear resistance with non-marking properties and the option of high visibility colors.
The adoption of super size foam filled marine fenders enlarged the space between the ships and parapet of the wharf, and improves the depth of the berth, consequently improves the ability of loading/unloading, so as to create a new approach for upgrading the wharfs and improved the handling efficiency.  Â

â‘¡ Double acting cylinder: supply air alternately from both sides of piston, output force in one or two directions.
â‘¢ Rodless cylinder: general term for cylinders without piston rod. There are magnetic cylinder and cable cylinder.
The reciprocating cylinder is called swing cylinder. The inner cavity is divided into two parts by the blade, and the air is supplied to the two cavities alternately. The output shaft swings, and the swing angle is less than 280 °. In addition, there are rotary cylinder, gas-liquid damping cylinder and stepping cylinder.
The electric actuator is mainly used for rotating and swinging conditions. Its advantage lies in the fast response time and the precise control of speed, position and torque through the feedback system. But when it needs to complete the linear motion, it needs to be transformed by mechanical devices such as toothed belt or screw rod, so the structure is relatively complex, and there are high requirements for the working environment and the professional knowledge of the operation and maintenance personnel.
advantage
(1) The requirement for users is low. The principle and structure of the cylinder are simple, easy to install and maintain, and the requirements for users are not high. Electric cylinder is different, engineering personnel must have certain electrical knowledge, otherwise it is likely to be damaged due to misoperation.
(2) The output force is large. The output force of the cylinder is proportional to the square of the cylinder diameter; The output force of the electric cylinder is related to three factors: cylinder diameter, motor power and screw pitch. The larger the cylinder diameter and power, the smaller the screw pitch, the greater the output force. The theoretical output force of a cylinder with a diameter of 50 mm can reach 2000 n. for the electric cylinder with the same diameter, although the products of different companies are different, they are basically no more than 1000 n. Obviously, the cylinder has more advantages in terms of output force.
(3) Strong adaptability. The cylinder can work normally in high and low temperature environment, and has the ability of dustproof and waterproof, which can adapt to all kinds of harsh environment. Because of a large number of electrical components, the electric cylinder has high requirements for the environment and poor adaptability.
