The difference between hydraulic cylinder and hydraulic cylinder

The cylinder pushes the piston with gas to make the cylinder move up and down.

Hydraulic cylinder, which uses liquid (hydraulic oil) to push the piston and make the cylinder move up and down.

In terms of weight, the hydraulic cylinder is heavier than the hydraulic cylinder with the same volume.

In the form of output, the load output by the hydraulic cylinder is relatively light, and the load of the hydraulic cylinder is heavy.

In terms of bearing pressure, the pressure of the cylinder is less than that of the hydraulic cylinder.

In terms of materials, cylinders are generally made of aluminum (and steel), and hydraulic cylinders are made of steel (so hydraulic cylinders are heavier than cylinders of the same size).
