Airtac SSA Single-Acting Compact Cylinder SSA63X30SB
The AirTAC Airtac SSA Single-Acting Compact Cylinder SSA63X30SB 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 SSA63X30SB
The AirTAC SSA63X30SB is a 63 mm bore compact single-acting push-type cylinder with a 30 mm stroke. Air pressure extends the rod, while an internal mechanical spring retracts it upon release. Because it requires just one air line and one solenoid port, you cut down on fittings and simplify valve requirements. This unit delivers a true 1382.6 N net push at 0.5 MPa, reaching 2006.1 N at 0.7 MPa, with the return spring force already subtracted from the raw pneumatic output.
This configuration includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches, plus a male-thread piston rod (-B) sized M18x1.5. The short riveted body drastically minimizes axial mounting depth compared to traditional round-body alternatives. A fixed NBR bumper handles end-of-stroke deceleration, though it is not an adjustable air cushion. Operating speed ranges from 50-500 mm/s.

| 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 SSA63X30SB Is Used
Heavy-Duty Stamping Ejector
Utilize the 1382.6 N net push at 0.5 MPa to eject thick metal blanks from a die, taking advantage of the 30 mm stroke for rapid part clearance.
Riveting Clamp Fixture
Secure heavy housings during a riveting cycle; the male M18x1.5 rod threads directly into a custom clamp arm, while the compact body fits within tight tooling towers.
Pallet Diverting Gate
Actuate a heavy diverter arm on a packaging line; the single-acting design uses only one air line, reducing valve complexity in high-density conveyor zones.
Is the Airtac SSA Single-Acting Compact Cylinder SSA63X30SB the Right Cylinder?
When sizing this model, compare its 1382.6 N net push at 0.5 MPa against adjacent bores. Stepping down, the SSA50 provides 874.7 N at 0.5 MPa, making the 63 mm bore necessary for heavier ejection or clamping duties. This represents the maximum standard stroke ceiling of 30 mm for the series. The bore dictates the PT1/4 air port and the 20 mm rod diameter.
Remember that spring-return mechanics mean the SSA63X30SB cannot hold a mid-stroke load; when air is released, the spring drives the rod back to its rest position. For load holding without live pressure, an external mechanical device is required. This specific SKU confirms the -S magnet for sensing and the -B male M18x1.5 rod thread (default is female M10x1.5). Operating pressure must be 0.2-1.0 MPa to function properly.
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 SSA63X30SB 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, giving you a true design figure. The cylinder requires a minimum of 0.2 MPa to overcome the spring.
No, the internal spring drives the rod back to its retracted rest position upon air loss. It does not lock or hold a mid-stroke load. The fixed NBR bumper only decelerates the stroke near the end, so an external rod lock is needed for holding.
