Do You Want Things To Move Right Every Time?
Imagine building with toy blocks. You want your blocks to stack in the right spot, again and again. But sometimes they wiggle or don’t line up. That makes you feel upset. Servo linear actuators are like super helpers. They always move things to the right place. No wiggle. No guesswork. At Jimi Technology, we make these helpers for lots of big jobs.
What Is a Servo Linear Actuator?
A servo linear actuator looks like a strong little stick. It can push, pull, lift, or lower things. It can even tilt objects or help robots move. Press a button, and it goes to the exact spot you want—quick as a flash!
Table: What Can Servo Linear Actuators Do?
Jimi makes many types: for robots, TV lifts, medical beds, or factory lines.
Why Is Precision Important?
Precision means doing things the right way every time. Like coloring inside the lines for every picture, not just once. If a robot arm misses its place, the whole job can go wrong. Factories need everything to be exact. So do doctors, scientists, and engineers.
Jimi’s servo linear actuators make sure things move just right, every time. No mistakes, no guessing.
1-2-3: Precision—It’s More Than Just “Close Enough”
Let’s talk about three easy words:
- Accuracy: Did it go to the spot you wanted?
- Repeatability: Can it go there again and again?
- Resolution: How small a move can it make?
If you always tie your shoes the same way, you have good “repeatability.” If your bow sits at the middle, that’s “accuracy.” If you can move your fingers just a little, that’s “resolution!”
What Makes Servo Linear Actuators So Good?
Look inside: You see smart parts working together—just like a team!
Closed-Loop Control System (The Big Boss!)
Servo linear actuators use a closed-loop control system. That means a “brain” (controller) checks and fixes your moves all the time.
- Feedback sensors (the “eyes”) see how far you go.
- If you are not in the right spot, the “brain”—a PID controller—makes you try again.
- This keeps things on track—like a train that stays on the rails.
Other helpers, like stepper motors, don’t have this system. They might miss a step and not even know it!
High-Resolution Encoders (Tiny Rulers)
The encoders are like rulers that can see really, really small details. They use “counts,” “lines,” or “scales” to watch even a tiny move.
- Rotary encoders watch spins.
- Linear encoders watch straight lines.
- Absolute encoders remember where you are, even if the power goes out!
- Incremental encoders count each move as it happens.
Servo Motors: The Muscle with Finesse
A servo motor in your actuator is not just strong. It’s smart. It can move fast or slow. It stops exactly where it should, even if something gets in the way. That means your job is always done right.
Smart Controllers: The Brain Power
Servo drives use special programs. The most famous is called PID (Proportional-Integral-Derivative) control. It checks for mistakes, fixes them, and keeps the movement smooth.
Strong Parts: The Structure
You want your toys to be strong so they don’t break, right? Jimi uses:
- Ground ball screws and roller screws—no wobbles!
- Linear guides and bearings—smooth, no sticking.
- Tough housings—keeps out dust, dirt, or bumps.
Some of Jimi's ball screw actuators use preloaded nuts and anti-backlash tricks to make sure there's no space to wiggle.
Direct Drive Magic
Jimi makes direct drive linear actuators too. These don’t use gears or screws. That means no play, no delay, just fast, super-stiff, perfect moves.
Keeping It Perfect: How We Control Problems
Even the best need help staying perfect! Here’s how Jimi does it:
- No backlash (loose spots) by using preloaded nuts, and special designs
- Lots of stiffness so big loads won’t make it bend or slip
- Thermal stability—stays the same even when things get hot or cold!
- We build with super care—no loose bits, always tight checks
Where Do You Need Super Precision?
Look at some places where only the best will do:
- Semiconductor factories (making computer chips)
- Medical machines (helping doctors)
- Robots (in smart factories)
- Laser and optical machines (lining up lights perfectly)
- CNC machines (cutting metal or wood shapes)

Numbers Don’t Lie: How Precise Are Servo Linear Actuators?
Table: Some Precision Facts
| Feature | Usual Range (Jimi’s Best) | Why It Matters |
|---|---|---|
| Accuracy | ±1 to 20 µm | Always hits the target |
| Super Accuracy | < ±0.1 µm | For tiny, exact jobs |
| Repeatability | ±0.5 to 5 µm | Gets it right every time |
| Super Repeatability | < ±0.1 µm | For perfect repeats |
| Resolution | 0.001 to 1 µm | Smallest move possible |
| Backlash (screw) | < 10 µm | Almost no play at all |
| Backlash (direct) | 0 µm | No play, ever |
| Stiffness | 100 N/µm | Holds firm, no bend |
| Update Rates | 1-10kHz | Very fast corrections |
Why Other Actuators Aren’t As Good
Some machines use hydraulic or pneumatic actuators. These can be leaky or bouncy. They are not as exact. Stepper motors don’t check where they are—they guess! That means sometimes they step wrong. You can trust Jimi’s servo linear actuators to never guess.
