Airtac SSA Single-Acting Compact Cylinder SSA50X10SB
The AirTAC Airtac SSA Single-Acting Compact Cylinder SSA50X10SB is a genuine single-acting COMPACT cylinder (single acting, push type) with a Ø50mm bore and 10mm 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 SSA50X10SB
The AirTAC SSA50X10SB is a compact single-acting push-type cylinder where air extends the rod and an internal spring retracts it. It provides 874.7 N of net push force at 0.5 MPa and 1267.4 N at 0.7 MPa, with the return spring force already subtracted for accurate sizing. A short 10 mm stroke keeps the overall footprint minimal for tight fixtures.
This specific configuration includes a built-in piston magnet for AirTAC reed or electronic switches and a male M18x1.5 threaded rod end. The riveted body design saves axial mounting depth where standard cylinders cannot fit. It requires only one air line and one solenoid port to operate, simplifying plumbing while delivering a robust 50 mm bore output.
Airtac SSA Single-Acting Compact Cylinder SSA50X10SB Technical Specifications
| Model | Airtac SSA Single-Acting Compact Cylinder SSA50X10SB |
|---|---|
| Series | SSA compact single-acting cylinder |
| Bore size | Ø50 mm |
| Stroke | 10 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.

Where the Airtac SSA Single-Acting Compact Cylinder SSA50X10SB Is Used
Heavy-Duty Part Ejection
Uses the 874.7 N net push at 0.5 MPa to positively eject heavy machined metal blocks from a crowded machining center.
Riveting Fixture Clamp
Applies reliable clamping force in a short 10 mm stroke, with the male M18x1.5 rod threading directly into the tooling.
Vertical Lift Stop
Lifts a 44.6 kg payload vertically with a 2:1 safety margin, relying on the single air line to extend and the spring to return.
Is the Airtac SSA Single-Acting Compact Cylinder SSA50X10SB the Right Cylinder?
When sizing this model, compare its 874.7 N net push at 0.5 MPa against adjacent bores. Stepping down to the SSA40 yields 545.6 N, while stepping up to the SSA63 provides 1382.6 N. A safe working load is approximately 525 N, offering a 2:1 margin for a vertical lift of around 44.6 kg. The 10 mm stroke is well within the 30 mm maximum limit for this series.
Remember that air pressure must be at least 0.2 MPa to overcome the return spring. Because it is spring-retracted, the SSA50X10SB does not hold a mid-stroke load without live pressure; use an external rod lock for holding. This unit features a PT1/4 port, a 20 mm rod diameter, the -S magnet option, and the -B male rod thread.
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 SSA50X10SB FAQ
The net push force is 874.7 N at 0.5 MPa and 1267.4 N at 0.7 MPa. These figures already account for the internal return spring resistance, giving you the true usable output for your design.
No, the internal spring drives the rod back to its retracted rest position on air loss. It requires a minimum of 0.2 MPa to overcome the spring and does not lock or hold a mid-stroke load without live pressure.
