Airtac STA Single Acting Compact Guided Cylinder STA25X5
The AirTAC Airtac STA Single Acting Compact Guided Cylinder STA25X5 is a genuine single-acting COMPACT cylinder (single acting, pull type) with a Ø25mm 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 STA25X5
The AirTAC STA25X5 is a compact single-acting pull-type cylinder where air retracts the rod and an internal spring extends it out. It yields 177.7 N of net pull at 0.5 MPa, making it perfect for brief tensioning or hold-down duties. The short riveted body saves axial mounting depth where a round-body or profile cylinder will not fit.
This 5 mm stroke model uses a 10 mm piston rod and an M5x0.8 air port. It relies on a fixed NBR bumper to decelerate the stroke end rather than an adjustable air cushion. Because this SKU lacks the -S option, it has no piston magnet and cannot take a magnetic switch.
Airtac STA Single Acting Compact Guided Cylinder STA25X5 Technical Specifications
| Model | Airtac STA Single Acting Compact Guided Cylinder STA25X5 |
|---|---|
| Series | STA compact single-acting cylinder |
| Bore size | Ø25 mm |
| Stroke | 5 mm |
| Acting type | Single acting, pull type |
| Port size | M5×0.8 |
| Rod end thread | M5×0.8 female / M8×1.25 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 (Ø25mm, Pull)
| Pressure | Pull force (net) |
|---|---|
| 0.5 MPa | 178 N |
| 0.7 MPa | 260 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. |
|---|---|
| 25 | Bore size in mm. |
| ×5 | 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 STA25X5 Is Used
Tension Gate Return
Uses the 177.7 N net pull to hold a sliding gate closed against external pressure, with the internal spring automatically pushing it back open when air is cut.
Short Hold-Down Clamp
Applies downward tension on light sheet metal during a brief machining cycle, exploiting the 5 mm stroke for a rapid, compact clamping action.
Package Deflector
Retracts a routing flap on a packaging line to divert small cartons, relying on the spring to safely extend the flap back to its default position.
Is the Airtac STA Single Acting Compact Guided Cylinder STA25X5 the Right Cylinder?
When sizing this unit, verify if the 177.7 N net pull at 0.5 MPa is sufficient. Stepping down to the STA20 gives 108.9 N, while stepping up to the STA32 provides 290.1 N. This 5 mm stroke is well under the 30 mm series ceiling.
Remember the spring-extend behavior: on air loss the rod drives to its extended rest position and does not hold a mid-stroke load. This base configuration confirms a 25 mm bore, 5 mm stroke, M5x0.8 port, female rod-end thread, and no magnet.
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 STA25X5 FAQ
This cylinder provides a net pull of 177.7 N at 0.5 MPa and 260.1 N at 0.7 MPa. It requires an operating pressure of 0.2-1.0 MPa, as at least 0.2 MPa is needed to overcome the internal return spring.
No, this specific SKU does not include the -S option, meaning it lacks a piston magnet and cannot take a magnetic switch. You would need the STA25X5S variant to use AirTAC reed or electronic switches.
