Airtac SSA Single-Acting Compact Cylinder SSA50X25B
The AirTAC SSA Single-Acting Compact Cylinder SSA50X25B 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 SSA50X25B
The AirTAC SSA50X25B is a compact single-acting push-type cylinder where air pressure extends the rod and an internal spring retracts it. It generates 874.7 N of net push at 0.5 MPa, meaning the return spring force is already subtracted to give you a real design figure. The short riveted body saves axial mounting depth where a standard round-body cylinder will not fit.
This specific SKU features a male M18x1.5 piston rod thread and a 20 mm rod diameter. Because it lacks the -S option, there is no piston magnet and it cannot take magnetic switches. A fixed NBR bumper handles end-of-stroke deceleration, but it is not an adjustable air cushion.
Airtac SSA Single-Acting Compact Cylinder SSA50X25B Technical Specifications
| Model | Airtac SSA Single-Acting Compact Cylinder SSA50X25B |
|---|---|
| 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.

| SSA | Compact single acting, push type cylinder series. |
|---|---|
| 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). |
| B | Male-thread piston rod (omit = female thread). |
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 SSA50X25B Is Used
Heavy-Duty Stamping
Applies the 874.7 N net push to seat or stamp components securely in a tight fixture.
Pallet Ejection
Uses the male M18x1.5 rod to push loaded pallets out of a conveyor station before retracting.
Vertical Lift Stops
Extends to halt a 44.6 kg vertical load, relying on the fixed NBR bumper for end deceleration.
Is the Airtac SSA Single-Acting Compact Cylinder SSA50X25B the Right Cylinder?
When sizing this model, consider the neighbouring bores: the SSA40 provides 545.6 N at 0.5 MPa, while the SSA63 offers 1382.6 N at 0.5 MPa.
Confirm the 25 mm stroke is within the 30 mm ceiling for this series. Operating pressure must be 0.2-1.0 MPa, as at least 0.2 MPa is required to overcome the spring. Remember that on air loss the spring drives the rod to its retracted rest position; it does not hold a mid-stroke load. The bore-fixed port is PT1/4.
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 SSA50X25B FAQ
The net push force is 874.7 N at 0.5 MPa and 1267.4 N at 0.7 MPa. These figures already subtract the internal return spring force.
No, this specific SKU lacks the -S magnet option, so it cannot take reed or electronic switches. You would need the -S variant for position sensing.
