Airtac SSA Single-Acting Compact Cylinder SSA16X25N
The AirTAC SSA Single-Acting Compact Cylinder SSA16X25N is a genuine single-acting COMPACT cylinder (single acting, push type) with a Ø16mm 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 SSA16X25N
The AirTAC SSA16X25N is a compact single-acting push-type cylinder where air pressure extends the rod and an internal mechanical spring retracts it. This 16 mm bore unit generates 80.5 N of net push force at 0.5 MPa, a figure that already accounts for the return spring resistance. Operating across a 50-500 mm/s speed range, it uses a fixed NBR bumper to absorb end-of-stroke shock rather than an adjustable cushion.
Designed with a short riveted body, this pneumatic actuator minimizes axial mounting depth in crowded machinery. It requires only a single M5x0.8 air line and one solenoid port to drive motion, simplifying plumbing and lowering valve costs. 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 SSA16X25N Technical Specifications
| Model | Airtac SSA Single-Acting Compact Cylinder SSA16X25N |
|---|---|
| Series | SSA compact single-acting cylinder |
| Bore size | Ø16 mm |
| Stroke | 25 mm |
| Acting type | Single acting, push type |
| Port size | M5×0.8 |
| Rod end thread | M3×0.5 female / M5×0.8 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 (Ø16mm, Push)
| Pressure | Push force (net) |
|---|---|
| 0.5 MPa | 81 N |
| 0.7 MPa | 121 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 SSA16X25N Is Used
Small Part Ejection
Uses the 80.5 N net push at 0.5 MPa to positively eject small stamped components from a die without occupying valuable tooling depth.
Package Diverting
Briefly extends 25 mm to knock lightweight cartons off a production line, relying on the spring to retract instantly when air is cut.
Is the Airtac SSA Single-Acting Compact Cylinder SSA16X25N the Right Cylinder?
When sizing this model, compare its 80.5 N net output at 0.5 MPa against adjacent bores: the SSA12 yields 46.5 N, while the SSA20 provides 134.1 N. The 25 mm stroke sits safely below the 30 mm maximum limit for this series.
Confirm your parameters before ordering: 16 mm bore, 25 mm stroke, M5x0.8 port, female M3x0.5 rod-end thread, and no magnet. Operating pressure must stay between 0.2 and 1.0 MPa, as a minimum of 0.2 MPa is required to overcome the internal spring. Remember that upon air loss the spring forces the rod back to its retracted state; it will not hold a mid-stroke load without external locking mechanisms.
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 SSA16X25N FAQ
This single-acting cylinder provides a net push force of 80.5 N at 0.5 MPa and 120.7 N at 0.7 MPa. These values already subtract the return spring resistance, giving you the true usable output for your design calculations.
No, this specific SKU does not include a piston magnet. To use AirTAC reed or electronic switches, you must select the -S option code. Additionally, it requires at least 0.2 MPa of air pressure to overcome the internal spring and extend the rod.
