[Optimized Sliding Section]
Stable operation and long life were realized by the adoption of special compounds for wear resistant packing, the adoption of high frequency grease, and by the optimization of the seal function.

[Long service life]
By optimizing the sliding section, a durability of more than 20 million cycles is realized.

[Stable Operation]
By optimizing the structure of the sliding section, the starting pressure is made constant even in repeated operation frequency.
Since the starting pressure is constant, the operating time is also constant. It contributes to stable operation without frequent stops.

[Same standard dimensions]
It has the same dimensions as the standard type Twin rod cylinder STR2 Series, and can be replaced without changing the design or modifying the equipment.
