Airtac STA Single Acting Compact Guided Cylinder STA12X30B
The AirTAC Airtac STA Single Acting Compact Guided Cylinder STA12X30B is a genuine single-acting COMPACT cylinder (single acting, pull type) with a Ø12mm 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 STA12X30B
The AirTAC STA12X30B is a compact single-acting pull-type cylinder where air retracts the rod and an internal spring extends it back out. At its maximum standard 30 mm stroke, this 12 mm bore unit generates 32.4 N of net pull force at 0.5 MPa. The short riveted body saves axial mounting depth where a round-body or profile cylinder will not fit, making it ideal for tight machinery.
This specific SKU features a male M5x0.8 threaded piston rod and an M5x0.8 air port. Because it lacks the -S option, it has no piston magnet and cannot accept magnetic switches. A fixed NBR bumper decelerates the stroke end, but note that on air loss the spring drives the rod to its extended rest position rather than holding a mid-stroke load.
Airtac STA Single Acting Compact Guided Cylinder STA12X30B Technical Specifications
| Model | Airtac STA Single Acting Compact Guided Cylinder STA12X30B |
|---|---|
| Series | STA compact single-acting cylinder |
| Bore size | Ø12 mm |
| Stroke | 30 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.

Where the Airtac STA Single Acting Compact Guided Cylinder STA12X30B Is Used
Tension Return Mechanism
Pulls a lightweight tension cable or linkage inward with 32.4 N force, relying on the internal spring to automatically release the load when air pressure drops.
Small Gate Retraction
Uses the 30 mm stroke to pull a compact diverter gate closed on a conveyor line, saving axial space while the spring ensures the gate fails open.
Film Hold-Down Pull
Draws a packaging film clamp back during the wrapping cycle, providing precise 19 N safe working load tension without requiring bulky pneumatic hardware.
Is the Airtac STA Single Acting Compact Guided Cylinder STA12X30B the Right Cylinder?
When sizing this model, the 32.4 N net pull at 0.5 MPa yields a safe working load of roughly 19 N (about 60% of capacity) and a vertical lift capability of approximately 1.7 kg with a 2:1 margin. If your application requires more pulling power, sizing up to the STA16 provides 66.4 N at 0.5 MPa. As the smallest bore in the series, there is no smaller STA variant to step down to.
This configuration respects the 30 mm stroke ceiling and operates between 0.2 and 1.0 MPa, needing at least 0.2 MPa to overcome the return spring. Confirm the 12 mm bore, 30 mm stroke, M5x0.8 port, male M5x0.8 rod thread, and the absence of a magnet for your setup.
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 STA12X30B FAQ
This single-acting pull cylinder provides a net pull force of 32.4 N at 0.5 MPa and 49.4 N at 0.7 MPa. It requires an operating pressure of 0.2 to 1.0 MPa, with a minimum of 0.2 MPa necessary to overcome the internal return spring.
No, this specific SKU does not have the -S option, meaning it lacks a piston magnet and cannot accept AirTAC reed or electronic switches. You would need the -S variant to enable sensor groove detection.
