Firstly, the size of the cylinder diameter needs to be determined based on the required load, air pressure, and direction of action.

Firstly, the size of the cylinder diameter needs to be determined based on the required load, air pressure, and direction of action. It can be calculated using formulas or selected based on the output table.

Next is the itinerary, which should be determined based on the distance of the workpiece movement, and at the same time, to facilitate installation and debugging, appropriate margin should be reserved.

Next is the series, which have different characteristics and should be selected according to needs.

Next is the installation type, such as basic type, foot seat type, flange type, U-shaped hook, shaft ear type, etc., depending on the actual situation.

There are also normal working conditions, such as medium and ambient temperature usually ranging from -20 to 80 ℃, and working pressure generally ranging from 0.1 to 1.0MPa. Before installation, it should be tested at 1.5 times the working pressure without any air leakage.

For electric cylinders, the shape should be considered, including linear and folding types, and the load should also be taken into account. The cylinder diameter should be determined according to the load, and the stroke should be determined according to the demand. The speed should also be considered.

In addition, when selecting cylinders, it is important to pay attention to the piston area and adjust it according to the output. There are also load ratios and working pressures, and the pressure should be less than 85% of the inlet pressure of the pressure reducing valve.

After determining the cylinder diameter and stroke, choose the cylinder type and installation form. There are various installation forms, such as basic type, foot type, rod side flange type, etc.

The buffering form should also be selected, including whether there is a buffer, rubber buffer, air buffer, and hydraulic buffer.

Finally, the selection of electromagnetic switches is also important. Magnetic switches installed on cylinders are mainly used for position detection. Before use, it is necessary to confirm that the cylinder has a built-in magnetic ring.
