Airtac SSA Single-Acting Compact Cylinder SSA50X25
The AirTAC SSA Single-Acting Compact Cylinder SSA50X25 is a genuine single-acting COMPACT cylinder (single acting, push type) with a Ø50mm 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 SSA50X25
The AirTAC SSA50X25 is a compact single-acting push-type cylinder where air pressure extends the rod and an internal spring retracts it. It provides a substantial 874.7 N net push at 0.5 MPa, making it suitable for robust short-stroke tasks. The quoted force is already net of the return spring, giving you a real design figure rather than raw air pressure.
This model features a 50 mm bore, a 25 mm stroke, and a PT1/4 port. Its short riveted body saves axial mounting depth where a standard round-body cylinder will not fit. Because it requires only one air line and one solenoid port, plumbing is significantly simplified. A fixed NBR bumper decelerates the stroke end, though it is not an adjustable air cushion.
Airtac SSA Single-Acting Compact Cylinder SSA50X25 Technical Specifications
| Model | Airtac SSA Single-Acting Compact Cylinder SSA50X25 |
|---|---|
| Series | SSA compact single-acting cylinder |
| Bore size | Ø50 mm |
| Stroke | 25 mm |
| Acting type | Single acting, push type |
| Port size | PT1/4 |
| Rod end thread | M10×1.5 female / M18×1.5 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 (Ø50mm, Push)
| Pressure | Push force (net) |
|---|---|
| 0.5 MPa | 875 N |
| 0.7 MPa | 1267 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.

|---|---|
| 50 | Bore size in mm. |
| ×25 | Stroke length in mm (single-acting max 30 mm). |
| S | Built-in magnet for magnetic-switch sensing (omit = none). |

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 SSA50X25 Is Used
Heavy-Duty Stamping
Applies the 874.7 N net push at 0.5 MPa to seat or stamp components securely within a 25 mm travel distance.
Pallet Diverter
Uses the single air line to extend and divert heavy pallets, relying on the internal spring for a fail-safe retraction.
Product Ejection
Ejects dense packaged goods from a tight fixture, taking advantage of the compact riveted body to save axial depth.
Is the Airtac SSA Single-Acting Compact Cylinder SSA50X25 the Right Cylinder?
When sizing this model, consider the neighboring bores: the SSA40 yields 545.6 N net push at 0.5 MPa, while the SSA63 provides 1382.6 N at the same pressure.
Remember the 30 mm maximum standard stroke ceiling and the spring-return behavior. If air pressure drops, the spring drives the rod back to rest; it does not hold a mid-stroke load. This specific SKU lacks the -S magnet option, so it cannot accept position switches. The rod end features a female M10x1.5 thread, with a male M18x1.5 available on the B variant.
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 SSA50X25 FAQ
The SSA50X25 delivers 874.7 N of net push force at 0.5 MPa and 1267.4 N at 0.7 MPa. These figures already account for the return spring resistance.
No, it cannot hold a mid-stroke load. The SSA50X25 is a single-acting push cylinder that requires at least 0.2 MPa to overcome the spring. When air is released, the spring drives the rod back to its retracted rest position.
