if not, which rules sais so ?
thanks

The actuators themselves are allowed, it is the motors that are not.

If you were to adapt/mount a FIRST legal motor (from the kit or as described in the motor section of the rules) to the actuator shown it would be legal for use in competition

We have used the top one before and replaced it with an older FP. They cannot take the load that the FP can make, so i wouldn’t use these in high load applications.
I don’t know anything about the second one listed.
