Airtac SSA Single-Acting Compact Cylinder SSA12X30S
The AirTAC Airtac SSA Single-Acting Compact Cylinder SSA12X30S is a genuine single-acting COMPACT cylinder (single acting, push type) with a Ø12mm bore and 30mm stroke. Air pushes 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 SSA Single-Acting Compact Cylinder SSA12X30S
The AirTAC SSA12X30S is a compact single-acting push-type cylinder where air pressure extends the rod and an internal spring retracts it. At 12 mm bore, it provides 46.5 N net push at 0.5 MPa, meaning the return spring force is already subtracted from the raw air force. This makes it a real design figure for your calculations.
It features a short riveted body that minimizes axial mounting depth in crowded fixtures. A fixed NBR bumper decelerates the stroke end; it is not an adjustable air cushion. Because this model includes the S option, it has a built-in piston magnet for position sensing with AirTAC reed or electronic switches.
Airtac SSA Single-Acting Compact Cylinder SSA12X30S Technical Specifications
| Model | Airtac SSA Single-Acting Compact Cylinder SSA12X30S |
|---|---|
| Series | SSA compact single-acting cylinder |
| Bore size | Ø12 mm |
| Stroke | 30 mm |
| Acting type | Single acting, push 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, Push)
| Pressure | Push force (net) |
|---|---|
| 0.5 MPa | 47 N |
| 0.7 MPa | 69 N |
These are NET output forces — the return-spring force is already deducted. Single-acting push only; the spring performs the opposite stroke. Size with a safety margin.

Where the Airtac SSA Single-Acting Compact Cylinder SSA12X30S Is Used
Small Part Ejection
Pushes lightweight machined components out of a tight fixture using 46.5 N net force, with the spring returning the rod automatically.
Test Probe Actuation
Extends a 6 mm rod to press sensors against boards, relying on the built-in magnet to confirm extension via an electronic switch.
Thin-Wall Clamping
Holds delicate plastic housings in place during a quick labeling cycle, saving axial depth with its short riveted body.
Is the Airtac SSA Single-Acting Compact Cylinder SSA12X30S the Right Cylinder?
Size this 12 mm bore against its neighbor: the SSA16 yields 80.5 N net push at 0.5 MPa if you need more force, while the SSA12 is the smallest available option in the series. This SSA12X30S uses the maximum standard stroke of 30 mm. It requires at least 0.2 MPa operating pressure to overcome the internal spring.
Configuration confirmed: 12 mm bore, 30 mm stroke, M5x0.8 port, female M3x0.5 rod thread, and the S magnet option. The spring drives the rod to rest on air loss, so it cannot hold a mid-stroke load without external live pressure. Operating speed ranges from 50-500 mm/s.
Quick checklist
- ✓ Net push 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 SSA Single-Acting Compact Cylinder SSA12X30S FAQ
The net push force is 46.5 N at 0.5 MPa and 69.2 N at 0.7 MPa. These values already subtract the return spring resistance, giving a safe working load of roughly 28 N for a 2:1 margin.
Air extends the rod, and releasing air lets the internal spring retract it. The S option provides a built-in magnet for AirTAC reed or electronic switches. It needs at least 0.2 MPa to overcome the spring.
