What is the working principle of the cylinder?

Linear cylinders are divided into piston type and non-piston type, and lubricating oil is not needed when used; Swing and rotating cylinders are divided into plane rotating cylinders and angle pressing cylinders when working; The pneumatic claw and finger cylinder work with the clamping claw. The working principle of the cylinder is the retraction and extension of the cylinder piston. Cylinder is divided into linear motion cylinder, oscillating cylinder, rotating cylinder, air claw cylinder and finger cylinder. The principle of cylinder is the retraction and extension of cylinder piston. Linear cylinder is the most widely used, which can be divided into piston type and non-piston type. Diaphragm cylinder has better sealing performance and no friction resistance. Lubricating oil is not needed when it is used, and it is usually only used for the fastening link of production process control. Swing and rotating cylinders can be divided into plane or angular pressure cylinders when moving; Air claws and finger cylinders, like fingers, have the function of grabbing objects on the cylinder. Moreover, there are mounting holes on the two jaws, and corresponding fixtures can be made according to different products. Million car purchase subsidy
