qgs cylinder model meaning









QGS cylinder selection method


1. Select the cylinder type from the action mode:





2. Selection of cylinder bore inner diameter size:



Calculation formula: cylinder thrust F0=0.25πD2 P

Cylinder pulling force F0=0.25π (D2-d2) P

In the formula: D-cylinder piston diameter (cm)

d-cylinder piston rod diameter (cm)

P-Cylinder working pressure (kgf/cm2)

F0-theoretical push-pull force of the cylinder (kgf)

Note: 1. The above output calculation is applicable to the cylinder speed range of 50~500mm/s;
2. The cylinder is installed vertically, and the upward thrust is about 50% of the theoretically calculated thrust.
3. When the cylinder is used horizontally and transversely, the actual output is basically equal to the theoretically calculated thrust considering the inertia factor.
4. Users can select the appropriate cylinder size from the theoretical output force table of the double-acting cylinder in our company's sample according to the load, working pressure, and direction of action.

3. Selection of cylinder stroke:
1. Confirm the moving distance of the workpiece;
2. Compare the standard stroke tables of each series of our company's samples and select the minimum standard stroke that exceeds the moving distance of the workpiece as the cylinder stroke.
[Example] Workpiece moving distance 93mm
Cylinder stroke 100mm (standard stroke)





4. Selection of cylinder buffer form:
1. No buffer cylinder;2. Fixed buffer cylinder;3. Adjustable buffer cylinder.

5. Selection of lubrication method:
1. Cylinder with oil lubrication;2. Cylinder without oil lubrication.

6. Selection of induction switch: (If position signal output is required, you can choose a cylinder with a magnetic switch, determine the working voltage and current, and select an appropriate magnetic switch)
1. Steel belt installation;2. Track installation;3. Tie rod installation;4. Direct installation.


7. Selection of cylinder series:
Based on the above conditions, select the appropriate series of cylinders from the sample.

8. Selection of installation form:
1. Basic type;2. Tripod type (axial or transverse);3. Flange type (front flange type or rear flange type);4. Suspended ear type (single earring type or double earring type);
5. Trunnion type (rod side trunnion type, rod-less trunnion type, middle trunnion type and trunnion support type).

9. Selection of suitable cylinder accessories: (piston rod end accessories)
1. I-type single elbow joint;2. Y-type double elbow joint;3. Floating joint.
