Applications and features
The EHSG series double acting single rod piston cylinders are the actuator which reciprocates linearly in hydraulic system. its features are simple in structure, reliable in operation, convenient in assemble and disassemble easy in maintenance, ect.. In addition, there are several varieties of connecting mode and can be provided with the cushioning devices.
The cylinders are widely used in engineering machinery, mining machinery, lifting-transportation machinery, metallurgical machinery and other machinery.

Notes:
1.The speed ratio o mains the ratio of the effective areas of piston to that of the piston rod chamber.
2.In principle, the max.stroke S:
when φ=1.33,S=8D(cylinder bore)
when φ=1.46, S=10D (cylinder bore)
when φ=2, S=12D(cylinder bore)
- To meet the customers need, when S>the values stipulated in the table, it should be fixed through negotiation.
- 4.As for the min. stroke for trunnion and middle flange connection, please use the values in table 5,6,7 and 8.
