Airtac STA Single Acting Compact Guided Cylinder STA12X30SB
The AirTAC Airtac STA Single Acting Compact Guided Cylinder STA12X30SB 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 STA12X30SB
The AirTAC STA12X30SB is a compact single-acting pull-type cylinder where air retracts the rod and an internal spring extends it out. It provides 32.4 N of net pull at 0.5 MPa and 49.4 N at 0.7 MPa. The short riveted body saves axial mounting depth where a round-body cylinder will not fit. This 12 mm bore unit features a 6 mm rod and a 30 mm stroke.
This configuration includes a built-in piston magnet for AirTAC reed or electronic switches, plus a male M5x0.8 rod thread. A fixed NBR bumper decelerates the stroke end. The safe working load is roughly 19 N, allowing a vertical lift of about 1.7 kg with a 2:1 margin.
Airtac STA Single Acting Compact Guided Cylinder STA12X30SB Technical Specifications

| 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 |

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 STA12X30SB Is Used
Tension Return Mechanism
Pulls a lightweight tension cable back to its open resting state using 32.4 N of net force at 0.5 MPa.
Gate Hold-Down Release
Retracts a small diverter gate against the spring when air is applied, allowing packages to pass.
Test Fixture Clamping
Uses the male M5 rod thread to pull a delicate sample securely into place during lab testing.
Is the Airtac STA Single Acting Compact Guided Cylinder STA12X30SB the Right Cylinder?
When sizing this 12 mm bore, stepping up to the STA16 yields 66.4 N of net pull at 0.5 MPa, whereas this STA12 is the smallest available bore in the series. The 30 mm stroke represents the maximum standard travel limit for this family. Because the spring extends the rod on air loss, the unit does not hold a mid-stroke load without live pressure.
This model is configured with the S magnet option for sensing and the B option for a male M5x0.8 rod end. It requires an M5x0.8 air port and a minimum operating pressure of 0.2 MPa to overcome the internal spring. Operating pressure ranges up to 1.0 MPa.
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 STA12X30SB FAQ
The net pull force is 32.4 N at 0.5 MPa and 49.4 N at 0.7 MPa. These figures already account for the internal return spring, meaning the air only retracts the rod.
No. The internal spring drives the rod to its extended rest position when air is removed. It requires at least 0.2 MPa to overcome the spring and does not lock or hold a mid-stroke load.
