Airtac SSA Single-Acting Compact Cylinder SSA25X30B
The AirTAC Airtac SSA Single-Acting Compact Cylinder SSA25X30B is a genuine single-acting COMPACT cylinder (single acting, push type) with a Ø25mm 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 SSA25X30B
The AirTAC SSA25X30B is a compact single-acting push-type cylinder where air pressure extends the rod and an internal mechanical spring retracts it. Because it only requires one air line and a single solenoid port to drive the motion, you cut down on fittings and simplify valve requirements. It yields a true 216.9 N of net push at 0.5 MPa, meaning the opposing return-spring force is already subtracted from the raw air pressure figure.
This specific SKU features a male M8x1.25 threaded piston rod end and operates at the 30 mm maximum standard stroke ceiling. The short riveted body conserves axial mounting depth in crowded fixtures. A fixed NBR bumper handles end-of-stroke deceleration, but note this is not an adjustable air cushion or a locking mechanism.
Airtac SSA Single-Acting Compact Cylinder SSA25X30B Technical Specifications
| Model | Airtac SSA Single-Acting Compact Cylinder SSA25X30B |
|---|---|
| Series | SSA compact single-acting cylinder |
| Bore size | Ø25 mm |
| Stroke | 30 mm |
| Acting type | Single acting, push type |
| Port size | M5×0.8 |
| Rod end thread | M5×0.8 female / M8×1.25 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 (Ø25mm, Push)
| Pressure | Push force (net) |
|---|---|
| 0.5 MPa | 217 N |
| 0.7 MPa | 315 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 SSA25X30B Is Used
Short-Stroke Part Ejection
Uses the 216.9 N net push at 0.5 MPa to positively eject machined components from a tight fixture, relying on the spring to reset automatically.
Package Lane Diverting
The male M8x1.25 rod threads directly into a diverting arm to push light cartons between conveyor belts without needing complex pneumatic plumbing.
Vertical Lift Stops
Lifts a 11.1 kg payload with a 2:1 safety margin, using the compact riveted body to fit within shallow vertical lift station frames.
Is the Airtac SSA Single-Acting Compact Cylinder SSA25X30B the Right Cylinder?
When sizing this unit, compare its 216.9 N net push at 0.5 MPa against adjacent bores: the SSA20 provides 134.1 N, while the SSA32 offers 346.6 N. A practical safe working load is roughly 130 N, or a vertical lift of about 11.1 kg with a 2:1 safety margin. You must supply at least 0.2 MPa of operating pressure to overcome the internal spring.
This configuration combines a 25 mm bore, 30 mm stroke, and an M5x0.8 port. It includes the -B option for a male M8x1.25 rod thread. Because this SKU lacks the -S magnet code, it cannot accept position sensing. If air pressure drops, the spring drives the rod back to rest; it will not hold a mid-stroke load without external devices.
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 SSA25X30B FAQ
This model provides a net push force of 216.9 N at 0.5 MPa and 315.1 N at 0.7 MPa. These figures already account for the subtraction of the internal return spring's resistance.
No, this specific SKU does not have the -S option, so it lacks a piston magnet and cannot accept reed or electronic switches. You would need the -S variant for position sensing.
