Airtac SSA Single-Acting Compact Cylinder SSA12X25S
The AirTAC Airtac SSA Single-Acting Compact Cylinder SSA12X25S is a genuine single-acting COMPACT cylinder (single acting, push type) with a Ø12mm bore and 25mm 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 SSA12X25S
The AirTAC SSA12X25S is a compact single-acting push-type cylinder where air extends the rod and an internal spring retracts it. It delivers 46.5 N of net push force at 0.5 MPa, making it ideal for light-duty clamping and ejection. Because the return spring force is already subtracted, you can size directly to this real-world output.
This model features a short riveted body that saves axial mounting depth in crowded machinery. It includes the -S option for a built-in piston magnet, allowing you to track position with an AirTAC reed or electronic switch. A fixed NBR bumper handles end-of-stroke deceleration, and the 6 mm rod uses an M5x0.8 port for straightforward pneumatic hookup.
Airtac SSA Single-Acting Compact Cylinder SSA12X25S Technical Specifications
| Model | Airtac SSA Single-Acting Compact Cylinder SSA12X25S |
|---|---|
| Series | SSA compact single-acting cylinder |
| Bore size | Ø12 mm |
| Stroke | 25 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 SSA12X25S Is Used
Small Part Ejection
Uses the 46.5 N push stroke to eject small molded components from a tight fixture, saving axial space with its compact riveted body.
Package Diverting
Acts as a short-stroke pop-up diverter on a conveyor line, relying on the internal spring to retract quickly when air is released.
Lab Test Clamping
Secures delicate test samples with a safe 28 N working load, utilizing the built-in magnet to confirm clamp engagement.
Is the Airtac SSA Single-Acting Compact Cylinder SSA12X25S the Right Cylinder?
When sizing this 12 mm bore actuator, consider the neighboring SSA16, which provides 80.5 N of net push at 0.5 MPa if your application demands more force. The SSA12X25S requires a minimum operating pressure of 0.2 MPa to overcome the return spring and functions safely up to 1.0 MPa. Based on the 46.5 N output at 0.5 MPa, a safe working load is approximately 28 N, yielding a vertical lift capacity of about 2.4 kg with a 2:1 safety margin.
This configuration has a 25 mm stroke, well within the 30 mm ceiling for this series. Keep in mind that upon air loss, the spring drives the rod back to its retracted state; it will not hold a mid-stroke load without live pressure. This specific build includes the -S magnet for sensing and a female M3x0.5 rod-end thread.
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 SSA12X25S FAQ
This single-acting cylinder provides a net push force of 46.5 N at 0.5 MPa and 69.2 N at 0.7 MPa. These figures already account for the internal return spring resistance.
Air pressure extends the rod, while the internal spring retracts it upon air release, requiring a minimum of 0.2 MPa to operate. The included -S magnet allows you to use AirTAC reed or electronic switches for position detection.
