Airtac STA Single Acting Compact Guided Cylinder STA12X10
The AirTAC Airtac STA Single Acting Compact Guided Cylinder STA12X10 is a genuine single-acting COMPACT cylinder (single acting, pull type) with a Ø12mm bore and 10mm stroke. Air pulles the rod and an internal spring returns it, so one solenoid line drives the motion — ideal for short-stroke clamping and ejection in tight spaces.

About the Airtac STA Single Acting Compact Guided Cylinder STA12X10
The AirTAC STA12X10 is a compact single-acting pull-type cylinder where compressed air retracts the rod and an internal spring pushes it back out. It delivers 32.4 N of net pull at 0.5 MPa, safely handling a working load of roughly 19 N for reliable tensioning. This thin riveted body saves axial mounting depth where larger profile cylinders cannot fit.
Only one M5x0.8 air line and solenoid port are required since the internal spring manages the extension stroke. The 6 mm rod uses a female M3x0.5 thread, and a fixed NBR bumper decelerates the stroke ends. This SKU lacks a piston magnet, so position sensing is not supported without upgrading to an -S variant.
Airtac STA Single Acting Compact Guided Cylinder STA12X10 Technical Specifications
| Model | Airtac STA Single Acting Compact Guided Cylinder STA12X10 |
|---|---|
| Series | STA compact single-acting cylinder |
| Bore size | Ø12 mm |
| Stroke | 10 mm |
| Acting type | Single acting, pull type |
| Port size | M5×0.8 |
| Rod end thread | M3×0.5 female / M5×0.8 male (B) |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.2 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 50 – 500 mm/s |
| Cushion | Fixed NBR bumper |
| Max standard stroke | Up to 30 mm |
Specifications follow the official AirTAC SDA-family datasheet. Single-acting types start at 0.2 MPa (the spring must be overcome). Confirm against the product label before installation.
Net Output Force (Ø12mm, Pull)
| Pressure | Pull force (net) |
|---|---|
| 0.5 MPa | 32 N |
| 0.7 MPa | 49 N |
These are NET output forces — the return-spring force is already deducted. Single-acting pull only; the spring performs the opposite stroke. Size with a safety margin.

| STA | Compact single acting, pull type cylinder series. |
|---|---|
| 12 | Bore size in mm. |
| ×10 | Stroke length in mm (single-acting max 30 mm). |
| S | Built-in magnet for magnetic-switch sensing (omit = none). |

Thread: PT standard. SSA pushes out / spring returns; STA pulls in / spring extends. Related: SDA (double acting), SDAD (double rod), SDAJ (adjustable stroke).
Where the Airtac STA Single Acting Compact Guided Cylinder STA12X10 Is Used
Light Wire Tensioning
Pulls a light wire guide into position with 32.4 N of force, letting the spring automatically release the tension when air is removed.
Small Panel Hold-Down
Retracts a 6 mm rod to clamp thin electronic panels during assembly, saving axial space in dense manufacturing fixtures.
Flap Return Mechanism
Uses spring extension to push a packaging guide flap back open after air pressure retracts it, ensuring reliable cycling.
Is the Airtac STA Single Acting Compact Guided Cylinder STA12X10 the Right Cylinder?
When sizing this 12 mm bore, consider the next size up: the STA16 provides 66.4 N of net pull at 0.5 MPa for heavier tensioning. As the smallest bore in the series, there is no smaller STA option. This 10 mm stroke sits well below the 30 mm maximum limit. Remember that the spring extends the rod to its rest position on air loss, meaning it cannot hold a mid-stroke load without an external rod lock.
Confirm your requirements for a 12 mm bore, 10 mm stroke, M5x0.8 port, and female M3x0.5 rod thread. Because this base model has no internal magnet, you must specify the -S option if your application requires reed or electronic switches.
Quick checklist
- ✓ Net pull force at your working pressure
- ✓ Stroke ≤ 30 mm (single-acting limit)
- ✓ Single air line saves a valve/port
- ✓ Magnet (S) for sensors?
- ✓ Female (blank) or male (B) rod thread
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.2 – 1.0 MPa operating pressure.
- check Remember the spring performs the return stroke.
- check Avoid side load on the short piston rod.
- check Front/rear covers are riveted — do not dismantle.
- check Installation by qualified personnel per AirTAC docs.
Airtac STA Single Acting Compact Guided Cylinder STA12X10 FAQ
The STA12X10 provides a net pull force of 32.4 N at 0.5 MPa and 49.4 N at 0.7 MPa. These figures already account for the internal return spring resistance.
No, the internal spring drives the rod to its extended rest position when air is removed. It requires a minimum of 0.2 MPa to overcome the spring and retract the load.
