What is the stroke on a hydraulic cylinder?
The stroke of hydraulic cylinder is the amount of travel the piston rod can move in and out. It can be found by subtracting the maximum extended length of the hydraulic cylinder from it’s minimum compressed length.
Generally the compressed length is given along with the stroke. To find the maximum length of the cylinder, you have to add the two together.
Stroke lengths are standardized more or less in 2″ increments from 4″ to 24″, and larger increments above those lengths, such as 6″.
Another standardization is that the compressed length for cylinders of any given stroke is usually the same between cylinders. For example, most cylinders with a 12″ stroke will have a 22.25″ compressed length.
We can make a design according to customer’s requirements.If you require our engineer to make a design,please advise us the following specification:
1. Rated pressure
2. Working pressure
3. Test pressure
4. Working condition and environment ,for example ,temperature ,working frequency
5. Pulling force ,and return stroke force
6. Pulling and return speed
7. Assembly size
8. Seal ring requirements .For example , brand ,seal material etc .
9. Cylinder tube and cylinder rod raw material requirements
10. Piston rod surface treatment requirements, for example chroming film thickness,Surface hardness etc .
11. Painting and other spare parts requirements .
