Airtac SSA Single-Acting Compact Cylinder SSA12X10S
The AirTAC Airtac SSA Single-Acting Compact Cylinder SSA12X10S is a genuine single-acting COMPACT cylinder (single acting, push type) with a Ø12mm bore and 10mm 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 SSA12X10S
The AirTAC SSA12X10S 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, meaning the return spring's resistance is already subtracted from the raw air pressure. This 12 mm bore unit requires only one air line and one solenoid port, drastically simplifying plumbing for short-stroke ejection tasks.
Its short riveted body minimizes axial mounting depth in crowded fixtures. The piston features a built-in magnet for position sensing, and end-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion.
Airtac SSA Single-Acting Compact Cylinder SSA12X10S Technical Specifications
| Model | Airtac SSA Single-Acting Compact Cylinder SSA12X10S |
|---|---|
| Series | SSA compact single-acting cylinder |
| Bore size | Ø12 mm |
| Stroke | 10 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 SSA12X10S Is Used
Small Part Ejection
Pushes lightweight plastic components out of machining fixtures using its 46.5 N net output.
Packaging Diversion
Sorts small cartons on a conveyor line where a single air line simplifies valve requirements.
Lab Clamping
Holds delicate test samples in place during low-force assembly processes within tight enclosures.
Is the Airtac SSA Single-Acting Compact Cylinder SSA12X10S the Right Cylinder?
Selecting this model means sizing around its 46.5 N net push at 0.5 MPa, which translates to a safe working load of roughly 28 N or a vertical lift of about 2.4 kg with a 2:1 margin. If your application requires less force, you are at the bottom of the SSA range, but stepping up to the SSA16 increases the output to 80.5 N at 0.5 MPa. Keep in mind the 30 mm maximum stroke ceiling for this series.
This configuration features a 12 mm bore, 10 mm stroke, and an M5x0.8 port. The -S code indicates the built-in magnet for AirTAC reed or electronic switches. The rod end utilizes a female M3x0.5 thread. Remember that the spring drives the rod back upon air loss, so it cannot hold a mid-stroke load without external devices.
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 SSA12X10S FAQ
The net push force is 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, requiring a minimum of 0.2 MPa to overcome the spring. The built-in -S magnet allows tracking by AirTAC reed or electronic switches.
