Airtac SSA Single-Acting Compact Cylinder SSA40X15
The AirTAC Airtac SSA Single-Acting Compact Cylinder SSA40X15 is a genuine single-acting COMPACT cylinder (single acting, push type) with a Ø40mm bore and 15mm 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 SSA40X15
The AirTAC SSA40X15 is a compact single-acting push-type cylinder where air pressure extends the rod and an internal mechanical spring handles the retraction. Because it only needs one air line and one solenoid port to function, you cut down on fitting complexity and save valuable manifold space. At 0.5 MPa it generates 545.6 N of net push, and 796.9 N at 0.7 MPa, with the return spring force already subtracted from these figures.
Designed with a short riveted body, this unit minimizes axial mounting depth in crowded machinery where longer profile or round-body options fail to fit. The 16 mm piston rod utilizes a fixed NBR bumper at the stroke ends to absorb shock rather than relying on an adjustable cushion. Since this specific SKU lacks the -S magnet code, it cannot directly host reed or electronic switches.
Airtac SSA Single-Acting Compact Cylinder SSA40X15 Technical Specifications
| Model | Airtac SSA Single-Acting Compact Cylinder SSA40X15 |
|---|---|
| Series | SSA compact single-acting cylinder |
| Bore size | Ø40 mm |
| Stroke | 15 mm |
| Acting type | Single acting, push type |
| Port size | PT1/8 |
| Rod end thread | M8×1.25 female / M14×1.5 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 (Ø40mm, Push)
| Pressure | Push force (net) |
|---|---|
| 0.5 MPa | 546 N |
| 0.7 MPa | 797 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 SSA40X15 Is Used
Stamping Pin Ejection
Uses the 545.6 N net push at 0.5 MPa to eject small stamped metal pins from a die, relying on the internal spring to retract the rod quickly between cycles.
Carton Flap Folding
Applies short 15 mm strokes to fold corrugated carton flaps prior to sealing, with the compact riveted body fitting neatly into tight packaging line frames.
Bracket Clamping
Secures aluminum brackets during a machining process, taking advantage of the fixed NBR bumper to absorb the end-of-stroke shock without adjustment.
Is the Airtac SSA Single-Acting Compact Cylinder SSA40X15 the Right Cylinder?
When sizing this 40 mm bore actuator, compare its 545.6 N net push at 0.5 MPa against adjacent bores: the SSA32 provides 346.6 N, while the SSA50 yields 874.7 N. A practical safe working load is approximately 327 N, translating to a vertical lift capacity of about 27.8 kg when applying a 2:1 safety margin. This 15 mm stroke sits well below the 30 mm maximum limit for the series.
Remember that the internal spring drives the rod back to rest upon air loss, meaning this cylinder cannot hold a mid-stroke load without live pressure. Operating pressure must be 0.2-1.0 MPa, needing at least 0.2 MPa to overcome the spring. This configuration features a PT1/8 port, a female M8x1.25 rod-end thread, and no piston magnet.
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 SSA40X15 FAQ
The SSA40X15 delivers 545.6 N of net push at 0.5 MPa and 796.9 N at 0.7 MPa. These values are already net of the return spring force, meaning they represent the actual usable output for your design calculations rather than raw pneumatic force.
No, the internal spring drives the rod back to its retracted rest position when air is released, so it cannot hold a mid-stroke load. It also requires a minimum operating pressure of 0.2 MPa to overcome the spring and extend the rod.
