Airtac SSA Single-Acting Compact Cylinder SSA63X30S
The AirTAC Airtac SSA Single-Acting Compact Cylinder SSA63X30S 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 SSA63X30S
The AirTAC SSA63X30S is a 63 mm bore compact single-acting push-type cylinder, meaning compressed air extends the 20 mm rod while an internal spring handles the retraction. Delivering 1382.6 N of net push at 0.5 MPa and 2006.1 N at 0.7 MPa, this spring-return actuator is built for heavy-duty short-stroke tasks. The short riveted body saves axial mounting depth where a larger profile cylinder will not fit.
This specific configuration includes a built-in piston magnet (-S) for position sensing using AirTAC reed or electronic switches. The end-of-stroke deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion. Operating pressure spans 0.2 to 1.0 MPa, requiring at least 0.2 MPa to overcome the internal return spring.

| 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 |

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 SSA63X30S Is Used
Heavy-Duty Stamping Ejector
Uses the 1382.6 N net push at 0.5 MPa to eject thick metal blanks from a press die, relying on the internal spring to retract the 20 mm rod quickly when air is cut.
Multi-Point Forming Clamp
Applies up to 2006.1 N of extending force at 0.7 MPa to hold structural tubing during welding, with the short riveted body fitting neatly between tight tooling clearances.
Pallet Component Sorter
Pushes heavy cartons off a conveyor line using a 30 mm stroke, utilizing the built-in magnet to confirm retracted status before the belt advances.
Is the Airtac SSA Single-Acting Compact Cylinder SSA63X30S 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, whereas this 63 mm bore reaches 1382.6 N. A practical safe working load is approximately 830 N, representing about 60 percent of the 0.5 MPa figure, which translates to a vertical lift capacity of roughly 70.5 kg with a 2:1 safety margin. This model is configured with a 30 mm stroke, the maximum standard length for the series, a PT1/4 port, and a female M10x1.5 rod-end thread.
Because it is a spring-return actuator, the SSA63X30S does not hold a mid-stroke load if air pressure drops; the spring drives the rod back to its retracted rest position. If your application requires a powered return or mid-stroke locking, a double-acting SDA cylinder paired with an external rod lock would be necessary.
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 SSA63X30S 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 force subtracted by the internal return spring, giving you the true output capacity for your design calculations.
No, the SSA63X30S is a single-acting push type that uses an internal spring to retract. If air pressure is lost, the spring drives the rod back to its rest position. It cannot hold a mid-stroke load, and you would need a double-acting SDA with an external rod lock for that function.
