Airtac SSA Single-Acting Compact Cylinder SSA25X10N
The AirTAC Airtac SSA Single-Acting Compact Cylinder SSA25X10N is a genuine single-acting COMPACT cylinder (single acting, push type) with a Ø25mm bore and 10mm 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 SSA25X10N
The AirTAC SSA25X10N is a compact single-acting push-type cylinder where air pressure extends the rod and an internal spring retracts it. It provides 216.9 N of net push at 0.5 MPa, meaning the return spring force is already subtracted to give a reliable design figure. This 25 mm bore unit requires only one air line and one solenoid port, cutting fitting complexity and saving valve costs.
The short riveted body minimizes axial mounting depth in crowded fixtures. It features a 10 mm piston rod and an M5x0.8 port. End-of-stroke shock is handled by a fixed NBR bumper, which decelerates the motion but is not an adjustable cushion. This specific SKU lacks a piston magnet, so it cannot support position sensing without upgrading to the -S variant.
Airtac SSA Single-Acting Compact Cylinder SSA25X10N Technical Specifications
| Model | Airtac SSA Single-Acting Compact Cylinder SSA25X10N |
|---|---|
| Series | SSA compact single-acting cylinder |
| Bore size | Ø25 mm |
| Stroke | 10 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 SSA25X10N Is Used
Short-Stroke Part Clamping
Uses the 216.9 N net push at 0.5 MPa to secure light metal workpieces against a fixture stop during machining.
Package Diverter Ejector
Employs the 10 mm stroke to push small cartons off a conveyor belt, relying on the internal spring to retract instantly when air stops.
Compact Insertion Press
Fits into tight automated machinery footprints to press small pins or bearings, taking advantage of the short riveted body depth.
Is the Airtac SSA Single-Acting Compact Cylinder SSA25X10N the Right Cylinder?
When sizing this model, compare its 216.9 N net push at 0.5 MPa against adjacent bores. Stepping down to the SSA20 yields 134.1 N, while moving up to the SSA32 provides 346.6 N. A practical safe working load is roughly 130 N, or about 11.1 kg for a vertical lift with a 2:1 safety margin.
Remember the 30 mm maximum stroke ceiling for standard models. Because it is spring-returned, the SSA25X10N does not hold a mid-stroke load on air loss; the spring drives it back to rest. Confirm your requirements for the 25 mm bore, 10 mm stroke, M5x0.8 port, female rod-end thread, and lack of a 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 SSA25X10N FAQ
The net push force is 216.9 N at 0.5 MPa and 315.1 N at 0.7 MPa. These figures already account for the internal return spring resistance. It requires a minimum operating pressure of 0.2 MPa to overcome the spring.
No, this specific SKU does not include a piston magnet. To use AirTAC reed or electronic switches, you must select the -S option code variant which adds the built-in magnet for sensing.
