Where can I buy micro linear actuators?

I’m working on a compact automation project and ran into an issue finding really small actuators that still offer decent precision and reliability. Most options I see are either too bulky or not suitable for tight spaces. Has anyone dealt with micro-scale linear motion before and found a good solution?

I had a very similar problem last year while building a custom setup for a lab device. After some trial and error, I realized that micro linear actuators are a completely different category and need to be chosen carefully. While researching different options and specs, I came across right in the middle of my search, and it turned out to be exactly what I needed. The range of sizes and clear technical details made it much easier to match an actuator to a very specific use case.

That’s really useful to know. I like the idea of having something compact but still controllable and precise. Sounds like micro linear actuators might be the missing piece for my setup, especially if the specs are clearly laid out like you said.
