Airtac STA Single Acting Compact Guided Cylinder STA32X30
The AirTAC Airtac STA Single Acting Compact Guided Cylinder STA32X30 is a genuine single-acting COMPACT cylinder (single acting, pull type) with a Ø32mm bore and 30mm 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 STA32X30
The AirTAC STA32X30 is a compact single-acting pull-type cylinder engineered for short-stroke tensioning tasks. Compressed air retracts the 12 mm rod, yielding 290.1 N of net pull at 0.5 MPa, while an internal spring pushes it back out when air is released. Because the quoted force is already net of the spring, you can size directly to this 290.1 N rating without manual subtraction.
This 32 mm bore actuator features a space-saving riveted body that minimizes axial mounting depth in tight machinery. It operates at 50-500 mm/s and relies on a fixed NBR bumper to decelerate the stroke end, rather than an adjustable air cushion. A single PT1/8 port and solenoid are all that is required for plumbing.
Airtac STA Single Acting Compact Guided Cylinder STA32X30 Technical Specifications
| Model | Airtac STA Single Acting Compact Guided Cylinder STA32X30 |
|---|---|
| Series | STA compact single-acting cylinder |
| Bore size | Ø32 mm |
| Stroke | 30 mm |
| Acting type | Single acting, pull type |
| Port size | PT1/8 |
| Rod end thread | M6×1.0 female / M10×1.25 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 (Ø32mm, Pull)
| Pressure | Pull force (net) |
|---|---|
| 0.5 MPa | 290 N |
| 0.7 MPa | 428 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. |
|---|---|
| 32 | Bore size in mm. |
| ×30 | 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 STA32X30 Is Used
Tension Gate Retraction
Uses the 290.1 N net pull to draw a diverter gate closed on a conveyor line, allowing the internal spring to push it back open when air is vented.
Carton Flap Hold-Down
Pulls a mechanical hold-down arm out of the way during box indexing, with the spring extending the rod to clamp the flap during the sealing cycle.
Vertical Lift Return
Lifts a 14.8 kg tooling head against gravity using compressed air, relying on the spring to safely lower the head when the pneumatic signal drops.
Is the Airtac STA Single Acting Compact Guided Cylinder STA32X30 the Right Cylinder?
When sizing this actuator, compare its 290.1 N net pull at 0.5 MPa against adjacent bores: the STA25 provides 177.7 N, while the STA40 offers 445.1 N. This 32 mm option fits applications needing roughly 174 N of safe working load (about 60 percent of the 0.5 MPa rating), which translates to a vertical lift capacity of approximately 14.8 kg with a 2:1 safety margin.
This specific SKU has a 30 mm stroke, the absolute maximum standard length for the STA family, and uses a female M6x1.0 rod-end thread. It lacks the -S magnet option, meaning it cannot accept reed or electronic switches. Remember that the spring extends the rod to rest on air loss; it will not hold a mid-stroke load without live pressure or an external lock.
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 STA32X30 FAQ
This 32 mm bore cylinder provides 290.1 N of net pull at 0.5 MPa and 428.3 N at 0.7 MPa. These figures already account for the internal return spring resistance, so no further subtraction is needed for your sizing calculations.
No, this specific SKU does not include the -S magnet code, so it cannot accept reed or electronic switches. You also must supply at least 0.2 MPa of operating pressure to overcome the return spring and retract the rod.
