Airtac SSA Single-Acting Compact Cylinder SSA32X25N
The AirTAC Airtac SSA Single-Acting Compact Cylinder SSA32X25N is a genuine single-acting COMPACT cylinder (single acting, push type) with a Ø32mm bore and 25mm 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 SSA32X25N
The AirTAC SSA32X25N is a compact single-acting push-type cylinder where air pressure extends the rod and an internal spring retracts it. This bore 32 mm unit provides 346.6 N of net push at 0.5 MPa, a real design figure already accounting for the return spring force. Its short riveted body minimizes axial mounting depth, fitting easily into crowded fixtures where longer profile cylinders cannot.
Because it requires only one air line and one solenoid port to drive the motion, plumbing stays simple and cost-effective. The unit relies on a fixed NBR bumper to decelerate the stroke end rather than 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 SSA32X25N Technical Specifications
| Model | Airtac SSA Single-Acting Compact Cylinder SSA32X25N |
|---|---|
| Series | SSA compact single-acting cylinder |
| Bore size | Ø32 mm |
| Stroke | 25 mm |
| Acting type | Single acting, push type |
| Port size | PT1/8 |
| Rod end thread | M6×1.0 female / M10×1.25 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 (Ø32mm, Push)
| Pressure | Push force (net) |
|---|---|
| 0.5 MPa | 347 N |
| 0.7 MPa | 508 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 SSA32X25N Is Used
Fixture Clamping
Applies 346.6 N of net force to hold aluminum castings securely during CNC machining, retracting instantly when air pressure drops.
Part Diverter
Pushes cartons off a main belt in tight transfer zones, utilizing the 25 mm stroke and compact body to fit between rollers.
Flap Folding
Extends to tuck packaging flaps on automated lines, relying on the fixed NBR bumper to absorb the end-of-stroke impact.
Is the Airtac SSA Single-Acting Compact Cylinder SSA32X25N the Right Cylinder?
When sizing this model, compare its 346.6 N net push at 0.5 MPa against adjacent bores: the SSA25 yields 216.9 N, while the SSA40 provides 545.6 N. A practical safe working load is roughly 208 N, allowing a vertical lift of about 17.7 kg with a 2:1 safety margin. Operating pressure must sit between 0.2 and 1.0 MPa, needing at least 0.2 MPa to overcome the spring.
This configuration features a 32 mm bore, 25 mm stroke, PT1/8 port, and a 12 mm rod with a female M6x1.0 thread. The stroke stays within the 30 mm standard ceiling. Remember that the spring actively drives the rod back to rest upon air loss; it will not hold a mid-stroke load without external live pressure or a separate locking device.
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 SSA32X25N FAQ
This single-acting cylinder delivers 346.6 N of net push at 0.5 MPa and 507.5 N at 0.7 MPa. These values already subtract the internal return spring force, giving you a true design figure for your application.
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. Without the magnet, position sensing is not possible.
