HELP: Micro Linear actuators

I was searching the web in vain for a very small linear actuator (with a stroke about 20mm and a few Newtons force) without much success. The smallest I found were Firgelli PQ-12

and LS-12

LS-6 is still in development. Can somebody please help me finding a smaller linear actuator?



Thank you!

2cm stroke isn't "very small". There are some actuators for auto-focus cameras much smaller than that.

Take a look at these devices:

Those may be too small for you. Here's something a bit bigger:

Do you need position control, or are limit switches enough?

Something else to look at:

NEXACT® PiezoWalk® linear drives feature travel ranges of 20 mm and push/pull force capacities to 10 N in a compact package of only 25 x 25 x 12 mm.

Those things are great, but they're very expensive. Those are used for precision alignment of optical components, operations in wafer fabs, and other applications where you need sub-nanometer precision.
