Airtac SSA Single-Acting Compact Cylinder SSA12X5SB
The AirTAC Airtac SSA Single-Acting Compact Cylinder SSA12X5SB 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 SSA12X5SB
The AirTAC SSA12X5SB is a compact single-acting push-type cylinder where air extends the rod and an internal spring retracts it. Delivering 46.5 N of net push at 0.5 MPa, it requires only one air line and one solenoid port, which simplifies plumbing and cuts valve costs in tight fixtures.
This 12 mm bore model features a short riveted body that minimizes axial mounting depth. It includes a built-in piston magnet for position sensing and a male M5x0.8 threaded rod end. A fixed NBR bumper handles end-of-stroke deceleration, as there is no adjustable air cushion.
Airtac SSA Single-Acting Compact Cylinder SSA12X5SB Technical Specifications
| Model | Airtac SSA Single-Acting Compact Cylinder SSA12X5SB |

| 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 |

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 SSA12X5SB Is Used
Micro-Clamping
Holds small electronic components during soldering with 46.5 N of extend force, retracting instantly when air pressure drops.
Part Ejection
Pushes lightweight molded parts off a conveyor line in confined spaces using a single M5 air line and a 5 mm stroke.
Lab Automation
Actuates a sample diverter gate with a safe 28 N working load, utilizing the male M5 rod end for direct tool mounting.
Is the Airtac SSA Single-Acting Compact Cylinder SSA12X5SB the Right Cylinder?
This 12 mm bore provides 46.5 N net push at 0.5 MPa, offering 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, note that 12 mm is the smallest available bore in this series. Stepping up to the SSA16 increases the output to 80.5 N at 0.5 MPa.
The 5 mm stroke is well within the 30 mm maximum limit. Because the spring drives the rod back upon air release, the SSA12X5SB will not hold a mid-stroke load without live pressure. This specific configuration includes the -S magnet for reed or electronic switches and the -B male M5x0.8 rod thread. The port size is M5x0.8.
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 SSA12X5SB 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.
No. Air extends the rod and the spring retracts it, requiring a minimum of 0.2 MPa to overcome the spring. Upon air loss, the spring drives the rod to its rest position, so it cannot hold a mid-stroke load without an external device.
