What are the advantages of double rod cylinder


The double-rod cylinder can also be called a double-axis cylinder, which is equipped with two piston rods inside. This type of cylinder uses a very short copper sleeve in the guide part to prevent it from getting stuck. The two shafts have a large floating space. The two guide shafts can only be used in positions with small lateral force. You can shake your hands when using it.


The most prominent advantage of the double-rod cylinder is that it can ensure high accuracy. First of all, the structure is scientifically designed and equipped with two guide shafts, in which the piston rod and link combination are floating shaft plates. When workshop workers use it, they will find that it can be subject to larger lateral forces, second only to the sliding cylinder. There are two types of double-rod cylinder inverted rods, namely copper rings and ball linear bearings. Ball linear bearings have higher accuracy, but are more expensive;copper ring bearings are cheap, but relatively rough.








Secondly, the double-rod cylinder has obvious advantages in installation. Because the double-rod cylinder adopts a standard embedded installation and fixation form, it can save a lot of space. In addition, it also has certain bending strength and torsional strength, and can also absorb part of the lateral load. The mounting plate has mounting holes on three sides, enabling loading from multiple positions.

The installation of the double-rod cylinder is also very simple and does not require the use of additional accessories. Because it uses two guide shafts, it has strong side resistance. Users can choose the appropriate installation location according to actual needs. It can be used even in some occasions that require relatively high installation accuracy, because it is specially equipped with two precise positioning holes to provide higher precision positioning installation.


The third characteristic of the double-rod cylinder is its high speed. The double-rod cylinder reduces resistance and improves buffering performance by extending the length of the cylinder barrel, improving the material of the sealing ring, and improving processing accuracy, allowing the cylinder to run at higher speeds.







Double rod cylinder thrust calculation


Cylinder inner diameter bottom area × system pressure = output force-----N
For example: cylinder diameter 40, system pressure 0.5MPA

20×20×π×0.5＝628N
Thrust force on the cylinder piston rod F1=π/4×D2×P×ß (N)
Tension force on the cylinder piston rod F2=π/4×(D2-d2)×P×ß(N)

F1: Thrust force when the piston rod is pushed out
F2: The pulling force when the piston rod is pulled back
D: Cylinder tube inner diameter (piston diameter)
d: Piston rod diameter
P: air source pressure
ß: Load rate (ß=65% at slow speed, ß=30% at fast speed)



Double rod cylinder should have double force
First calculate the thrust of the single cylinder, P (working pressure) x S (piston area)
The double-rod cylinder has twice the pushing force
