Hydraulic pressure that is generated in cylinder dur to the inertia of load shall be set at less than the maximum allowable pressure.
When using in case of retract, set the working pressure up to 6Mpa as measure.
If the working speed is below the speed range, the cylinder would get stick-slip or get stuck. And if the working speed is cut cross the speed range, the packing will get early abrasion and it will also reduce the effectiveness of the cushion.
