Airtac SSA Single-Acting Compact Cylinder SSA16X30
The AirTAC Airtac SSA Single-Acting Compact Cylinder SSA16X30 is a genuine single-acting COMPACT cylinder (single acting, push type) with a Ø16mm 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 SSA16X30
The AirTAC SSA16X30 is a compact single-acting push-type cylinder where air pressure extends the rod and an internal spring retracts it. It provides 80.5 N net push at 0.5 MPa and 120.7 N at 0.7 MPa, with the return spring force already subtracted for accurate sizing. This thin riveted body saves axial mounting depth where round-body units will not fit.
You only need one air line and one solenoid port to drive the motion, simplifying plumbing and cutting valve costs. The fixed NBR bumper decelerates the stroke end but is not an adjustable cushion. This SKU lacks a piston magnet, so it cannot take a magnetic switch.
Airtac SSA Single-Acting Compact Cylinder SSA16X30 Technical Specifications
| Model | Airtac SSA Single-Acting Compact Cylinder SSA16X30 |
|---|---|
| Series | SSA compact single-acting cylinder |
| Bore size | Ø16 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 (Ø16mm, Push)
| Pressure | Push force (net) |
|---|---|
| 0.5 MPa | 81 N |
| 0.7 MPa | 121 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 SSA16X30 Is Used
Small Part Ejection
Uses the 80.5 N net push to eject small molded components from a tight fixture without needing a return air line.
Package Diverting
Deploys a 30 mm stroke to push light cartons off a conveyor belt, relying on the internal spring to retract automatically.
Test Fixture Clamping
Holds delicate samples in a test rig with a calculated 48 N safe working load, saving axial depth in the compact setup.
Is the Airtac SSA Single-Acting Compact Cylinder SSA16X30 the Right Cylinder?
This 16 mm bore yields a safe working load around 48 N, roughly 60 percent of its 80.5 N output at 0.5 MPa, which translates to a vertical lift of about 4.1 kg with a 2:1 margin. If you need less force, the SSA12 provides 46.5 N at 0.5 MPa. Stepping up to the SSA20 gives 134.1 N at 0.5 MPa.
This model uses a 30 mm stroke, the maximum standard travel for the series. Operating pressure is 0.2-1.0 MPa, needing at least 0.2 MPa to overcome the spring. The bore sets the port to M5x0.8 and the rod to 6 mm. It has a female M3x0.5 rod-end thread. The spring retracts the rod on air loss, so it will 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 SSA16X30 FAQ
The net push force is 80.5 N at 0.5 MPa and 120.7 N at 0.7 MPa. These figures already subtract the return spring resistance, giving you the true design output for your application.
No, this specific SKU does not include a piston magnet. You would need the SSA16X30S variant to use AirTAC reed or electronic switches for position sensing.
