Airtac SSA Single-Acting Compact Cylinder SSA63X30
The AirTAC Airtac SSA Single-Acting Compact Cylinder SSA63X30 is a genuine single-acting COMPACT cylinder (single acting, push type) with a Ø63mm bore and 30mm 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 SSA63X30
The AirTAC SSA63X30 is a 63 mm compact single-acting push-type cylinder where air pressure extends the rod and an internal spring retracts it. It provides 1382.6 N of net push at 0.5 MPa, making it the highest-force option in this series. The quoted force is already net of the return spring, giving you a real design figure rather than raw air pressure. This SKU has no piston magnet and cannot take a magnetic switch; the -S variant adds one for reed or electronic sensing.
Featuring a short riveted body, it saves axial mounting depth where a round-body cylinder will not fit. A fixed NBR bumper at each end decelerates the stroke end, though it is not an adjustable air cushion. With a safe working load around 830 N (about 60% of the 0.5 MPa figure), it can achieve a vertical lift of roughly 70.5 kg with a 2:1 safety margin.
Airtac SSA Single-Acting Compact Cylinder SSA63X30 Technical Specifications

| 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 |

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 (Ø63mm, Push)
| Pressure | Push force (net) |
|---|---|
| 0.5 MPa | 1383 N |
| 0.7 MPa | 2006 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 SSA63X30 Is Used
Heavy-Duty Stamping
Applies 1382.6 N of net force at 0.5 MPa for short-stroke stamping and forming tasks within a 30 mm travel limit.
Pallet Ejection
Pushes loaded pallets off an assembly station using a single air line, with the internal spring handling the retraction.
Rigid Workholding
Clamps heavy castings securely in tight fixtures where the compact riveted body minimizes axial mounting depth.
Is the Airtac SSA Single-Acting Compact Cylinder SSA63X30 the Right Cylinder?
This 63 mm bore model sits at the top of the SSA range, delivering 1382.6 N net push at 0.5 MPa. Stepping down, the SSA50 provides 874.7 N at the same pressure, which is a better fit if your application requires less force and a smaller footprint. Because this is the largest bore, there is no larger neighbor in the single-acting series to size up to.
The 30 mm stroke represents the maximum standard travel for this series. Operating pressure must be 0.2-1.0 MPa, needing at least 0.2 MPa to overcome the spring. On air loss, the spring drives the rod back to rest; it does not hold a mid-stroke load. This configuration includes a PT1/4 port, a 20 mm rod, and a female M10x1.5 rod-end 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 SSA63X30 FAQ
The net push force is 1382.6 N at 0.5 MPa and 2006.1 N at 0.7 MPa. These values already subtract the return spring force, so they represent the actual usable output.
No. It is a single-acting push cylinder where the internal spring retracts the rod when air is released. It cannot hold a mid-stroke load; for that, use a double-acting SDA with an external rod lock.
