Airtac SSA Single-Acting Compact Cylinder SSA20X20S
The AirTAC Airtac SSA Single-Acting Compact Cylinder SSA20X20S is a genuine single-acting COMPACT cylinder (single acting, push type) with a Ø20mm bore and 20mm 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 SSA20X20S
The AirTAC SSA20X20S is a compact single-acting push-type cylinder where air extends the rod and an internal spring retracts it. It provides 134.1 N of net push at 0.5 MPa, making it suitable for short-stroke clamping tasks. The short riveted body saves axial mounting depth where a round-body cylinder will not fit.
This model includes a built-in piston magnet for AirTAC reed or electronic switches. A fixed NBR bumper decelerates the stroke end, though it is not an adjustable air cushion. The bore sets the rod at 8 mm with an M4x0.7 female thread.
Airtac SSA Single-Acting Compact Cylinder SSA20X20S Technical Specifications
| Model | Airtac SSA Single-Acting Compact Cylinder SSA20X20S |
|---|---|
| Series | SSA compact single-acting cylinder |
| Bore size | Ø20 mm |
| Stroke | 20 mm |
| Acting type | Single acting, push type |
| Port size | M5×0.8 |
| Rod end thread | M4×0.7 female / M6×1.0 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 (Ø20mm, Push)
| Pressure | Push force (net) |
|---|---|
| 0.5 MPa | 134 N |
| 0.7 MPa | 197 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 SSA20X20S Is Used
PCB Edge Clamping
Applies 134.1 N of net push at 0.5 MPa to secure delicate circuit boards during routing without crushing the substrate.
Parts Diverter
Uses the 20 mm stroke to push lightweight plastic components off a belt, with the spring safely retracting the rod between cycles.
Flap Tucking
Tucks carton flaps in tight machinery where the compact riveted body minimizes axial footprint and simplifies single-line plumbing.
Is the Airtac SSA Single-Acting Compact Cylinder SSA20X20S the Right Cylinder?
This 20 mm bore yields 134.1 N net push at 0.5 MPa. Stepping down to SSA16 provides 80.5 N, while stepping up to SSA25 offers 216.9 N. Operating pressure is 0.2-1.0 MPa, requiring at least 0.2 MPa to overcome the spring.
The stroke is 20 mm, under the 30 mm maximum. The port is M5x0.8. The -S code confirms the magnet for position sensing. On air loss, the spring drives the rod to rest and does not hold a mid-stroke load. For a held load, use a double-acting SDA with an external rod lock.
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 SSA20X20S FAQ
The SSA20X20S provides a net push force of 134.1 N at 0.5 MPa and 196.9 N at 0.7 MPa. These figures already subtract the return spring force.
Air pressure extends the rod, while an internal spring retracts it upon air release. A minimum of 0.2 MPa is needed to overcome the spring. The -S code denotes a built-in magnet for AirTAC reed or electronic switches.
