Airtac SSA Single-Acting Compact Cylinder SSA50X5
The AirTAC Airtac SSA Single-Acting Compact Cylinder SSA50X5 is a genuine single-acting COMPACT cylinder (single acting, push type) with a Ø50mm bore and 5mm 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 SSA50X5
The AirTAC SSA50X5 is a compact single-acting push-type cylinder where air extends the rod and an internal spring retracts it. It delivers 874.7 N of net push at 0.5 MPa, making the 5 mm stroke highly effective for short, powerful movements. Because it is a spring-return design, the stated force is already netted, giving you a true design figure rather than raw air pressure.
This model features a 50 mm bore and a short riveted body that saves axial mounting depth where a longer cylinder would fail to fit. It requires only one air line and one solenoid port to drive the motion, simplifying your plumbing. The unit uses a fixed NBR bumper to decelerate the stroke end, which is not an adjustable air cushion.
Airtac SSA Single-Acting Compact Cylinder SSA50X5 Technical Specifications
| Model | Airtac SSA Single-Acting Compact Cylinder SSA50X5 |
|---|---|
| Series | SSA compact single-acting cylinder |
| Bore size | Ø50 mm |
| Stroke | 5 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.

| SSA | Compact single acting, push type cylinder series. |
|---|---|
| 50 | Bore size in mm. |
| ×5 | 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 SSA50X5 Is Used
Heavy-Duty Stamping
Applies the 874.7 N net push to seat metal components firmly in a die set during a short 5 mm stamping cycle.
Pallet Deflector
Uses the single-line plumbing advantage to briefly extend and divert heavy pallets on a crowded packaging line.
Short-Stroke Press
Leverages the compact riveted body to deliver high force in a tight vertical press without requiring excessive axial depth.
Is the Airtac SSA Single-Acting Compact Cylinder SSA50X5 the Right Cylinder?
When sizing this model, consider the SSA40 which provides 545.6 N of net push at 0.5 MPa, or step up to the SSA63 which yields 1382.6 N at the same pressure. The SSA50X5 provides a safe working load of roughly 525 N, operating at about 60 percent of its 874.7 N capacity, and can manage a vertical lift of approximately 44.6 kg with a 2:1 safety margin.
This configuration uses a 50 mm bore, a 5 mm stroke, and a PT1/4 port. It lacks the S magnet option, so it cannot accept magnetic switches. The female rod-end thread is M10x1.5. Operating pressure must be between 0.2 and 1.0 MPa, as 0.2 MPa is required just to overcome the return spring. Remember that on air loss the spring drives the rod back to rest, meaning it cannot hold a mid-stroke load.
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 SSA50X5 FAQ
The SSA50X5 provides 874.7 N of net push at 0.5 MPa and 1267.4 N at 0.7 MPa. These figures already account for the internal return spring resistance.
No, this specific SKU does not include the S magnet code, so it cannot accept reed or electronic switches. You would need the -S variant for position sensing.
