Nominal pressure

Pressure given to a cylinder for convenience of naming. It is not always the same as the working pressure (rated pressure) that guarantees performance under the specified conditions.

Maximum allowable pressure

The maximum allowable pressure generated in a cylinder (surge pressure, etc.).

Proof test pressure

Test pressure against which a cylinder can withstand without unreliable performance at the return to nominal pressure.

Minimum operating pressure

The minimum pressure that a cylinder placed horizontally without a load can work.

Notes)

• The hydraulic pressure generated in a cylinder due to the inertia of load must be lower than the maximum allowable pressure.
• In case that the lock nut is attached to the piston rod end thread part, increase the thread length (dimension A).
