Airtac SSA Single-Acting Compact Cylinder SSA63X5S
The AirTAC Airtac SSA Single-Acting Compact Cylinder SSA63X5S 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 SSA63X5S
The AirTAC SSA63X5S 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, making it ideal for heavy short-stroke ejection. The quoted force is already net of the return spring, providing a real design figure rather than raw air pressure. This 63 mm bore unit uses a 20 mm rod and a PT1/4 port.
Its short riveted body saves axial mounting depth where a standard round-body cylinder will not fit. The -S suffix indicates a built-in piston magnet for position sensing with AirTAC reed or electronic switches. A fixed NBR bumper handles end-of-stroke deceleration, though it is not an adjustable air cushion. With a 5 mm stroke, this actuator excels in tight fixtures requiring high impact force.
Airtac SSA Single-Acting Compact Cylinder SSA63X5S Technical Specifications
| Model | Airtac SSA Single-Acting Compact Cylinder SSA63X5S |
|---|---|
| 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.

Where the Airtac SSA Single-Acting Compact Cylinder SSA63X5S Is Used
Heavy-Duty Stamping
Applies 1382.6 N of net force at 0.5 MPa to seat or stamp small components securely within a confined die set.
Part Ejection
Uses the 5 mm stroke to rapidly eject heavy machined parts from a fixture, relying on the internal spring for a fast return.
Riveting Operations
Delivers a high-impact push to set rivets in tight assemblies where axial mounting depth is severely restricted.
Is the Airtac SSA Single-Acting Compact Cylinder SSA63X5S the Right Cylinder?
When sizing this model, consider the neighboring bore options. Stepping down, the SSA50 provides 874.7 N of net push at 0.5 MPa, which may be insufficient for heavy-duty tasks. The SSA63X5S offers a safe working load of roughly 830 N, about 60 percent of its 1382.6 N capacity at 0.5 MPa, and can vertically lift approximately 70.5 kg with a 2:1 safety margin.
This configuration features a 63 mm bore, a 5 mm stroke, a PT1/4 port, a female M10x1.5 rod-end thread, and the -S magnet option. Remember the 30 mm maximum standard stroke ceiling. Because the spring drives the rod back upon air release, it cannot hold a mid-stroke load without live pressure or an external rod lock. Operating pressure must be at least 0.2 MPa to overcome the spring, up to a maximum of 1.0 MPa.
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 SSA63X5S FAQ
The SSA63X5S provides a net push force of 1382.6 N at 0.5 MPa and 2006.1 N at 0.7 MPa. These values already account for the subtraction of the internal return spring force.
Air pressure extends the rod while the internal spring retracts it, requiring a minimum operating pressure of 0.2 MPa to overcome the spring. The -S suffix denotes a built-in magnet compatible with AirTAC reed or electronic switches for position detection.
