Airtac STA Single Acting Compact Guided Cylinder STA12X5S
The AirTAC Airtac STA Single Acting Compact Guided Cylinder STA12X5S is a genuine single-acting COMPACT cylinder (single acting, pull type) with a Ø12mm bore and 5mm 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 STA12X5S
The AirTAC STA12X5S is a compact single-acting pull-type cylinder where air retracts the 6 mm rod and an internal spring extends it back out. It provides 32.4 N of net pull at 0.5 MPa, making it suitable for light-duty tensioning and return-to-open tasks. Because it is spring-extended, the unit fails safely to the extended position on air loss.
This 12 mm bore model saves axial mounting depth thanks to its short riveted body, fitting where round-body cylinders cannot. The fixed NBR bumper decelerates the stroke end, and the built-in magnet (-S) supports position sensing with AirTAC reed or electronic switches.
Airtac STA Single Acting Compact Guided Cylinder STA12X5S Technical Specifications
| Model | Airtac STA Single Acting Compact Guided Cylinder STA12X5S |
|---|---|
| Series | STA compact single-acting cylinder |
| Bore size | Ø12 mm |
| Stroke | 5 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.

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 STA12X5S Is Used
Light Tensioning
Pulls small cables or light mechanical linkages with 32.4 N net force, releasing them automatically via the internal spring.
Gate Return
Holds a small access gate open using air pressure, then relies on the spring to push the rod out and close it when air is vented.
Part Ejection
Retracts a tiny 6 mm pin to release delicate components, using the spring-extend function to reset the mechanism to its starting state.
Is the Airtac STA Single Acting Compact Guided Cylinder STA12X5S the Right Cylinder?
When sizing this 5 mm stroke model, consider the neighboring STA16 bore, which offers a higher 66.4 N net pull at 0.5 MPa if your load requires more force. The STA12X5S itself yields a safe working load of roughly 19 N, or a vertical lift of about 1.7 kg with a 2:1 margin.
Remember the 30 mm maximum standard stroke ceiling for this series. Because the spring drives the rod out when air is released, this cylinder will not hold a mid-stroke load without live pressure or an external locking device. This specific configuration includes the S magnet option and a female M3x0.5 rod-end thread, operating on an M5x0.8 port.
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 STA12X5S FAQ
The STA12X5S provides 32.4 N of net pull at 0.5 MPa and 49.4 N at 0.7 MPa. It requires an operating pressure of 0.2-1.0 MPa, needing at least 0.2 MPa to overcome the internal return spring.
Air pressure retracts the rod, while the internal spring extends it when air is released. The -S option includes a built-in piston magnet for use with AirTAC reed or electronic switches to confirm end-of-stroke positions.
