Airtac SSA Single-Acting Compact Cylinder SSA12X30SB
The AirTAC Airtac SSA Single-Acting Compact Cylinder SSA12X30SB 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 SSA12X30SB
The AirTAC SSA12X30SB is a compact single-acting push-type cylinder where air extends the rod and an internal spring retracts it. It generates 46.5 N of net push force at 0.5 MPa, making it suitable for light-duty positioning. Because the quoted force is already net of the return spring, you can size directly to this real design figure without manual subtraction.
This model features a short riveted body that minimizes axial mounting depth in crowded fixtures. It includes a built-in piston magnet for position sensing and a male M5x0.8 threaded rod end. The stroke is set at the 30 mm series maximum, and end-of-travel shock is managed by a fixed NBR bumper rather than an adjustable cushion.
Airtac SSA Single-Acting Compact Cylinder SSA12X30SB Technical Specifications
| Model | Airtac SSA Single-Acting Compact Cylinder SSA12X30SB |
|---|---|
| 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 SSA12X30SB Is Used
Small Part Ejection
Pushes lightweight plastic components out of a machining nest using 46.5 N of net force at 0.5 MPa.
Thin-Wall Clamping
Secures delicate sheet material against a stop without crushing, leveraging the spring-return retraction.
Lab Automation Sorting
Diverts small vials on a conveyor belt with a 30 mm stroke, fitting easily into tight mechanical gaps.
Is the Airtac SSA Single-Acting Compact Cylinder SSA12X30SB the Right Cylinder?
When sizing this 12 mm bore actuator, consider the next size up: the SSA16 provides 80.5 N of net push at 0.5 MPa if your application requires more force. The SSA12X30SB operates on 0.2-1.0 MPa of air pressure, needing at least 0.2 MPa to overcome the internal spring. It uses an M5x0.8 port and moves at 50-500 mm/s.
This configuration includes the -S magnet for AirTAC reed or electronic switches and the -B male M5x0.8 rod thread. Remember that the spring drives the rod back to rest on air loss; it will not hold a mid-stroke load without live pressure or an external locking device.
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 SSA12X30SB FAQ
The net push force is 46.5 N at 0.5 MPa and 69.2 N at 0.7 MPa. These values already account for the internal return spring resistance, giving you a safe working load of roughly 28 N for a 2:1 margin.
Air pressure extends the rod, while an internal spring retracts it when air is released. It requires a minimum of 0.2 MPa to overcome the spring, and the -S code means a magnet is built in for compatibility with reed or electronic switches.
