Series CU4 SP

The CU4 gas spring is a very compact Bore Sealed gas spring with impressive force in a compact body. The maximum frequency for the spring is 100 strokes/minute.

Springs with stroke lengths over 25 mm should always be attached to the tool, using a flange or the tapped holes in the bottom of the spring. We also recommend fixing of shorter stroke springs for optimal service life.
The CU4 SP is equipped with a side port plate (SP) for applications where a sideport is needed (e.g., for use in hose systems).
