Slide cylinder refers to a cylindrical metal part in which the cylinder guides the piston to perform linear reciprocating motion. The air is in thecylinderThermal energy is converted into mechanical energy through gradual expansion;the gas is compressed by the piston in the compressor cylinder and the pressure is increased. Cylinders are generally used in fields such as printing, semiconductors, automation control, and robotics.
The working principle of the slide cylinder
Input compressed air into the cylinder on the fixed mold. The guide rod is pushed by the cylinder at one end and pushed in the opposite direction. The pushing stroke depends on the length of the guide rod. . Pneumatic slide cylinders are generally used for transportation of precision instruments, with relatively high accuracy. The guide rod cylinder has strong lateral load resistance. Determine the push and pull forces on the piston rod based on the amount of force required for the job. Therefore, the cylinder should be selected so that the output force of the cylinder has a slight margin. If the bore diameter is selected to be small, the output force will be insufficient and the cylinder will not work properly;but if the bore diameter is too large, it will not only make the equipment bulky and costly, but also increase air consumption, resulting in a waste of energy. When designing the clamp, a force-increasing mechanism should be used as much as possible to reduce the size of the cylinder.

Characteristics of slide cylinder
The piston of the cylinder is fixed on the piston rod. There are plates at both ends of the piston rod that can be firmly fixed on the machine table. The slide table moves back and forth on the piston rod. This is what we Slide cylinders commonly used in industrial machinery and equipment.
