LEGO has recently
come out with a new linear actuator piece as part of their new Power Function sets. The new actuators have a movement range of 5 studs, or about 1.6 in (4cm), which correspond to 26 full revolutions of the input shaft. The actuators also have a built in clutch mechanism to prevent damage from over-extension.
Klocki has more pictures of the actuators. This may be a useful alternative to
much more expensive linear actuators, like the ones from Firgelli.

Nice design of linear actuator. And it’s good that it can be use as an alternative to other actuator that is too much expensive.
