I'd like to know the difference in terms of usage between the standard Linear Actuator:

vs. the "mini" version:

Both of these parts provide the really fun mechanic of translating rotational energy into lateral motion (the essence of an actuator) in a particularly powerful way (in the sense of a worm screw).

My question revolves around the fact that the "standard" actuator is a lot more expensive. When new it comes sealed in its own plastic bag. The "mini" ones are a lot cheaper. Aside from general differences in geometry associated with the two parts, is there any other reason one would choose the "standard" actuator? Does it provide any mechanical virtues one would want to consider when designing a build?

The biggest difference I can think of that would impact my choice would be that the standard linear actuator is much more sturdy.

The standard linear actuator has a metal pole and is very rigid.

The mini linear actuators are made all of plastic, wiggle quite a bit, and whatever mechanism is inside will skip fairly easily.


The large linear actuator extends 5 studs (from 11 retracted to 16 fully extended)

The small one extends 3 studs (from 7 retracted to 10 fully extended)

That's a large functional difference.
