The difference between electric push rod and electric cylinderAug 21, 2024


  • Many people misunderstand the electric cylinder and the electric push rod, thinking they are the same product. In the eyes of people in Europe, the United States, Japan and South Korea, electric push rods and electric cylinders are a type of thing. But in China, we still divide them into two categories. Here, let's take a look at it.
  • The difference between electric cylinder and electric push rod is as follows:
1, Load capacity. The load capacity of the electric cylinder is stronger, and the load capacity of 0-100 tons can cope with different needs; The load of the electric push rod is usually tens to hundreds of kilograms, and the maximum thrust is basically difficult to exceed 10 tons.
2, The selection of screw. Electric cylinder multi-use ball screw to work, can achieve higher accuracy; The electric push rod is multi-purpose grinding ball screw, planetary screw, positioning accuracy is not high.
3, The speed. The electric cylinder can reach a speed of 2m/s; The speed of the electric push rod is generally <100mm/s.
4, The overall structure.The structure of the electric cylinder is the screw structure, and the motor of the electric cylinder is mostly servo motor or stepping motor, and the internal clearance is almost zero, so the repeated positioning accuracy of the electric cylinder is high, the application is more extensive, and the life is long (the total line can reach more than 100000KM).
The nuts inside the electric push rod are ordinary nuts, the internal structure gap is large, and the motors used are mostly AC and DC motors, so the repeated positioning accuracy is low, and the life is short;

5.Control methods. The electric cylinder can be started and stopped at any position, so that it can stop and stop, and can achieve multi-point accurate positioning; The electric push rod can generally only control 0 points and the maximum stroke of 2 positions.


6. Accuracy difference. The positioning accuracy of the electric cylinder is higher, the maximum can be ±0.01mm; The accuracy of the electric push rod is relatively low, and the accuracy of the AC electric push rod is 0.1-0.2mm.

7. Connection methods. The electric cylinder is mainly connected with the motor directly by the coupling, or the synchronous belt wheel connection, and the efficiency is very high; The electric push rod is mainly driven by gear, turbine scroll rod and so on, and the efficiency is low.

8, Application. Electric push rod in ordinary industrial applications more, such as window opening, when a latch, and electric cylinder in addition to the application of electric push rod accident, but also because of high precision, high transmission efficiency, in some high-end applications more.
