Airtac SSA Single-Acting Compact Cylinder SSA16X5S
The AirTAC Airtac SSA Single-Acting Compact Cylinder SSA16X5S is a genuine single-acting COMPACT cylinder (single acting, push type) with a Ø16mm 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 SSA16X5S
The AirTAC SSA16X5S is a compact single-acting push-type cylinder where air extends the rod and an internal spring retracts it. It provides 80.5 N of net push force at 0.5 MPa, making it suitable for short 5 mm ejection tasks. Because the return spring force is already subtracted, you can size directly to this output figure.
This model includes a built-in piston magnet for AirTAC reed or electronic switches. Its short riveted body minimizes axial mounting depth in crowded machinery. The fixed NBR bumper absorbs end-of-stroke shock without requiring adjustment.
Airtac SSA Single-Acting Compact Cylinder SSA16X5S Technical Specifications
| Model | Airtac SSA Single-Acting Compact Cylinder SSA16X5S |
|---|---|
| Series | SSA compact single-acting cylinder |
| Bore size | Ø16 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 (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 SSA16X5S Is Used
Sensor Part Ejection
Uses the 5 mm stroke to push small electronic components out of a test socket with 80.5 N force.
Thin Carton Flap Hold
Applies brief clamping pressure on lightweight packaging materials in a confined assembly cell.
PCB Alignment Stop
Extends briefly to square a circuit board against a hard stop before a downstream pick and place operation.
Is the Airtac SSA Single-Acting Compact Cylinder SSA16X5S the Right Cylinder?
When sizing this 16 mm bore unit, consider the SSA12 which yields 46.5 N net push at 0.5 MPa, or step up to the SSA20 for 134.1 N. This SSA16X5S configuration features a 5 mm stroke, an M5x0.8 port, a female M3x0.5 rod-end thread, and the -S magnet option.
Operating pressure must be 0.2-1.0 MPa to overcome the spring. With air released, the spring drives the rod back to rest; it does not hold a mid-stroke load. A safe working load is roughly 48 N, allowing a vertical lift of about 4.1 kg with a 2:1 margin.
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 SSA16X5S FAQ
The net push force is 80.5 N at 0.5 MPa and 120.7 N at 0.7 MPa. These figures already account for the internal return spring resistance.
Air pressure extends the rod while the internal spring handles retraction, requiring a minimum of 0.2 MPa to operate. The included -S magnet works with AirTAC reed or electronic switches for position detection.
