Airtac SSA Single-Acting Compact Cylinder SSA12X5B
The AirTAC Airtac SSA Single-Acting Compact Cylinder SSA12X5B 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 SSA12X5B
The AirTAC SSA12X5B is a compact single-acting push-type cylinder where air pressure extends the rod and an internal spring retracts it. It delivers 46.5 N of net push at 0.5 MPa, making it ideal for short-stroke ejection tasks. Because it requires only one air line and one solenoid port, plumbing is significantly simplified.
This 12mm bore unit features a 5mm stroke and a male M5x0.8 threaded piston rod. The short riveted body saves axial mounting depth where a standard round-body cylinder will not fit. A fixed NBR bumper decelerates the stroke end, but it is not an adjustable air cushion.
Airtac SSA Single-Acting Compact Cylinder SSA12X5B Technical Specifications
| Model | Airtac SSA Single-Acting Compact Cylinder SSA12X5B |
|---|---|
| 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 SSA12X5B Is Used
Small Part Ejection
Uses the 46.5 N net push to eject small molded components from a tight fixture without requiring a return air line.
Package Diverting
The 5mm stroke and compact riveted body fit between conveyor rollers to nudge lightweight cartons onto a branching track.
Test Probe Actuation
Applies precise low-force contact for electronic testing where the male M5x0.8 rod threads directly into a probe mount.
Is the Airtac SSA Single-Acting Compact Cylinder SSA12X5B the Right Cylinder?
When sizing this model, note that the 46.5 N net push at 0.5 MPa yields a safe working load of roughly 28 N, or a vertical lift of about 2.4 kg with a 2:1 margin. If you need less force, note that 12mm is the smallest available SSA bore. Stepping up to the SSA16 increases the 0.5 MPa net push to 80.5 N. The maximum standard stroke for this series is 30mm.
This configuration includes a male M5x0.8 rod thread and an M5x0.8 air port. It lacks the -S magnet option, so it cannot accept position switches. Remember that on air loss the spring drives the rod to its retracted rest position; it 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 SSA12X5B 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.
It is a single-acting push cylinder, so an internal spring retracts the rod to its rest position when air is released. It requires a minimum of 0.2 MPa to overcome the spring and extend.
