Airtac SSA Single-Acting Compact Cylinder SSA63X10S
The AirTAC Airtac SSA Single-Acting Compact Cylinder SSA63X10S is a genuine single-acting COMPACT cylinder (single acting, push type) with a Ø63mm 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 SSA63X10S
The AirTAC SSA63X10S is a 63 mm bore compact single-acting push-type cylinder with a 10 mm stroke. Compressed air extends the rod, while an internal spring handles the return, meaning you only need one air line and one solenoid port to drive the motion. This simplifies plumbing and cuts valve costs in tight fixtures. It delivers 1382.6 N of net push at 0.5 MPa, with the return spring force already subtracted from that figure.
The short riveted body saves significant axial mounting depth where a longer cylinder would fail to fit. A fixed NBR bumper decelerates the piston at the end of the stroke; this is not an adjustable air cushion, so external shock absorbers are recommended for high-energy approaches. The built-in magnet allows position detection using AirTAC reed or electronic switches.
Airtac SSA Single-Acting Compact Cylinder SSA63X10S Technical Specifications
| Model | Airtac SSA Single-Acting Compact Cylinder SSA63X10S |
|---|---|
| Series | SSA compact single-acting cylinder |
| Bore size | Ø63 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 (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 SSA63X10S Is Used
Heavy-Duty Stamping Ejector
Uses the 1382.6 N net push at 0.5 MPa to eject dense metal stampings from a die, relying on the short 10 mm stroke for rapid cycling.
Pallet Deflection Stop
Halts heavy pallets on a conveyor line using the spring-return mechanism, ensuring the rod safely retracts when air pressure is removed.
Riveting Head Clamp
Applies over 2000 N of force at 0.7 MPa to hold components firmly during a riveting process within a confined machine footprint.
Is the Airtac SSA Single-Acting Compact Cylinder SSA63X10S the Right Cylinder?
When sizing this model, consider the neighboring bores. Stepping down, the SSA50 provides 874.7 N of net push at 0.5 MPa, which may be insufficient if you need the full safe working load of roughly 830 N calculated for this 63 mm bore. Stepping up is not possible as 63 mm is the largest single-acting option available. This cylinder provides a vertical lift capacity of approximately 70.5 kg with a 2:1 safety margin.
The maximum standard stroke for this series is 30 mm, and this 10 mm unit operates within that limit. Operating pressure must be at least 0.2 MPa to overcome the return spring, up to a maximum of 1.0 MPa. Confirm the bore is 63 mm, stroke is 10 mm, port is PT1/4, and the rod end thread is female M10x1.5. The S suffix indicates the piston magnet is present for sensing. Remember that on air loss the spring drives the rod back to rest; it does not hold a mid-stroke load.
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 SSA63X10S FAQ
The net push force is 1382.6 N 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 output capacity for your design calculations.
No, the internal return spring drives the rod back to its retracted rest position when air is released. It cannot hold a mid-stroke load. You would need a double-acting SDA cylinder with an external rod lock for load holding.
