Airtac SSA Single-Acting Compact Cylinder SSA63X30B
The AirTAC Airtac SSA Single-Acting Compact Cylinder SSA63X30B 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 SSA63X30B
The AirTAC SSA63X30B is a 63 mm bore compact single-acting push-type cylinder with a 30 mm stroke. Compressed air extends the rod, while an internal mechanical spring retracts it, meaning the actuator is normally closed at rest. Operating at 0.5 MPa yields 1382.6 N of net push output, increasing to 2006.1 N at 0.7 MPa. Because the return spring force is already subtracted from these figures, you can size directly to the stated thrust without estimating spring losses.
This specific SKU features a male M18x1.5 piston rod thread and uses a PT1/4 air port. The short riveted body significantly reduces axial mounting depth compared to standard round-body alternatives, fitting easily into crowded machinery. A fixed NBR bumper handles end-of-stroke deceleration. Since this configuration lacks the -S magnet option, it cannot accept AirTAC reed or electronic switches.

| 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 SSA63X30B Is Used
Heavy-Duty Stamping Ejection
Provides 1382.6 N of net push at 0.5 MPa to positively eject dense metal stampings from a press die, utilizing the 30 mm stroke to clear the part quickly before the spring retracts.
Vertical Pallet Lifting
Raises a 70.5 kg fixture payload with a 2:1 safety margin, using the male M18x1.5 rod thread for a secure mechanical coupling in a short axial footprint where space is restricted.
Riveting Head Actuation
Drives a pneumatic riveting tool into position with up to 2006.1 N of force at 0.7 MPa, relying on the fixed NBR bumper to absorb the shock at the end of the extension stroke.
Is the Airtac SSA Single-Acting Compact Cylinder SSA63X30B the Right Cylinder?
When sizing this model, consider the neighboring bore options to match your exact thrust requirements. Stepping down to the SSA50 provides 874.7 N of net push at 0.5 MPa, which is a 37% reduction in force compared to this 63 mm unit. If you need maximum extension, this 63 mm bore is the largest available in the single-acting series, so exceeding 2006.1 N at 0.7 MPa requires moving to a double-acting SDA configuration. For practical load calculations, the safe working load is approximately 830 N, representing about 60% of the 1382.6 N figure at 0.5 MPa. In a vertical lifting scenario, this translates to safely raising roughly 70.5 kg with a 2:1 safety margin.
The 30 mm stroke represents the absolute maximum standard travel for this series; longer distances require a custom order or a different cylinder family. Keep in mind that upon air loss or pressure dropping below the 0.2 MPa minimum, the internal spring immediately drives the rod back to its retracted state. The SSA63X30B does not hold a mid-stroke load, so applications requiring position holding without live air pressure need an external rod lock. Confirm your fixture accommodates the PT1/4 port and the male M18x1.5 rod end.
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 SSA63X30B FAQ
The net push force is 1382.6 N at 0.5 MPa and 2006.1 N at 0.7 MPa. These values already account for the internal return spring resistance, meaning they represent the actual usable thrust available for your application.
No, it cannot hold a mid-stroke load. The SSA63X30B is a single-acting push cylinder where an internal spring drives the rod back to its fully retracted rest position whenever air pressure drops below 0.2 MPa or is removed. For load holding without live pressure, an external locking device is required.
