Features: Top limit overflow, automatic overflow over limit.
Uses: It is used in situations where space is extremely limited.

Ultra high pressure ultra low height hydraulic cylinder mainly used in space is very limited occasions, for example: Shipbuilding plant host adjustment, lifting of steam turbine maintenance in power plant and so on occasions.
● The top end is provided with an elastic sealing piece to avoid the impurity into the cylinder, extending cylinder life.
● Top finite overflow port, when the plunger over stroke, automatic overflow, safe and convenient.
● Overload test pressure is 1.5 times higher than the rated working pressure.
● Compared with the same kind cylinder, the same closed height, there is a longer lift stroke.
● G1/4” coupler and dust cap included on all models.

Ultra-Thin Jack with Ultra-High Pressure Manual Pump
● Requires minimal manual effort to achieve significant power output. For pressures of 150MPa or higher, an ultra-high pressure manual pump must be used.

Configuration for Simultaneous Lifting of 2 or 4 Jacks
● Multiple ultra-thin jacks (2, 4, or more) can be connected and controlled via a distribution valve.
● Pros: The configuration is relatively simple, and the overall cost is lower.
● Cons: Synchronous accuracy cannot be guaranteed. There is a risk of over-extension and other unpredictable issues.

● For a higher body height and a larger working stroke, please consider our ultra-thin hydraulic cylinders.

● For higher lifting capacities (300 tons, 500 tons, or more), please choose our electric hydraulic jacks.

● For applications requiring long-term support with a self-locking feature, please select our self-locking hydraulic cylinders.
