Airtac SSA Single-Acting Compact Cylinder SSA63X5
The AirTAC Airtac SSA Single-Acting Compact Cylinder SSA63X5 is a genuine single-acting COMPACT cylinder (single acting, push type) with a Ø63mm 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 SSA63X5
The AirTAC SSA63X5 is a compact single-acting push-type cylinder where air extends the rod and an internal spring retracts it. It generates 1382.6 N of net push at 0.5 MPa, with the return spring force already subtracted for accurate sizing. This 5 mm stroke unit needs just one air line and solenoid port, cutting plumbing complexity.
Designed for tight fixtures, the short riveted body minimizes axial mounting depth. It features a 20 mm rod, a PT1/4 port, and a fixed NBR bumper that absorbs end-of-stroke shock. This SKU lacks a piston magnet, so it cannot accept reed or electronic switches without the -S option.
Airtac SSA Single-Acting Compact Cylinder SSA63X5 Technical Specifications
| Model | Airtac SSA Single-Acting Compact Cylinder SSA63X5 |
|---|---|
| Series | SSA compact single-acting cylinder |
| Bore size | Ø63 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 (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.

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 SSA63X5 Is Used
Heavy-Duty Stamping
Applies 1382.6 N of net force at 0.5 MPa for short 5 mm stamping and marking operations in dense tooling layouts.
Rigid Workholding
Clamps heavy castings securely during machining, using the compact riveted body to save valuable axial fixture depth.
Part Ejection
Pushes finished components out of a press bed with a 20 mm rod, relying on the internal spring to retract instantly.
Is the Airtac SSA Single-Acting Compact Cylinder SSA63X5 the Right Cylinder?
When sizing this model, the 1382.6 N net push at 0.5 MPa supports a safe working load around 830 N, or a vertical lift of roughly 70.5 kg with a 2:1 margin. If less force is required, stepping down to the SSA50 provides 874.7 N at 0.5 MPa. As the largest bore in the series, there is no larger option; for higher force demands, a double-acting SDA should be evaluated.
The 5 mm stroke is well within the 30 mm maximum limit. Operating pressure must be 0.2-1.0 MPa, needing at least 0.2 MPa to overcome the spring. Remember that the spring drives retraction upon air loss, so the SSA63X5 will not hold a mid-stroke load without an external rod lock. This configuration confirms a 63 mm bore, 5 mm stroke, PT1/4 port, female M10x1.5 rod thread, and no magnet.
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 SSA63X5 FAQ
The SSA63X5 provides 1382.6 N of net push force at 0.5 MPa and 2006.1 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, this specific SKU does not include a piston magnet. To use AirTAC reed or electronic switches, you must specify the -S option. Without it, there is no sensing capability for position feedback.
