Airtac SSA Single-Acting Compact Cylinder SSA12X5
The AirTAC Airtac SSA Single-Acting Compact Cylinder SSA12X5 is a genuine single-acting COMPACT cylinder (single acting, push type) with a Ø12mm bore and 5mm 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 SSA12X5
The AirTAC SSA12X5 is a compact single-acting push-type cylinder where air extends the 6 mm rod and an internal spring retracts it. It provides 46.5 N of net push at 0.5 MPa, making it suitable for light-duty clamping and ejection in tight spaces.
This model features a short riveted body that minimizes axial mounting depth. Because it requires only one air line and one solenoid port, plumbing is simplified. The fixed NBR bumper decelerates the stroke end and is not an adjustable cushion.
Airtac SSA Single-Acting Compact Cylinder SSA12X5 Technical Specifications
| Model | Airtac SSA Single-Acting Compact Cylinder SSA12X5 |
|---|---|
| Series | SSA compact single-acting cylinder |
| Bore size | Ø12 mm |
| Stroke | 5 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.

Thread: PT standard. SSA pushes out / spring returns; STA pulls in / spring extends. Related: SDA (double acting), SDAD (double rod), SDAJ (adjustable stroke).
Where the Airtac SSA Single-Acting Compact Cylinder SSA12X5 Is Used
Micro-Clamp Station
Applies 46.5 N of net push at 0.5 MPa to secure small electronic components during soldering.
Parts Diverter Gate
Uses the 5 mm stroke to briefly extend and route lightweight plastic molds down a line.
Lab Test Ejector
Pushes small vials out of a testing nest with a safe working load of roughly 28 N.
Is the Airtac SSA Single-Acting Compact Cylinder SSA12X5 the Right Cylinder?
This 12 mm bore model yields 46.5 N net push at 0.5 MPa. Sizing upward, the SSA16 provides 80.5 N at the same pressure. The 5 mm stroke is well within the 30 mm maximum standard limit.
Operating pressure is 0.2-1.0 MPa, needing at least 0.2 MPa to overcome the spring. This SKU lacks the S magnet option and cannot take a switch. It uses an M5x0.8 port and a female M3x0.5 rod-end thread. The spring returns the rod on air loss but does not hold a mid-stroke load.
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 SSA12X5 FAQ
The net push force is 46.5 N at 0.5 MPa and 69.2 N at 0.7 MPa. These figures already subtract the return spring resistance.
No, this specific SKU lacks the S option and has no piston magnet. You must select the -S variant to use reed or electronic switches.
