CU 11800 - 18300

0 B

The CU gas spring is a very compact Bore Sealed gas

spring, that gives a high force in a limited space.

The max. 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 shorter stroke springs to be fastened for optimal service-life.

As an option, the CU springs can be delivered with a Side-Port plate (SP) for applications where a side-port is needed (i.e. for use in hose systems).
