Airtac SSA Single-Acting Compact Cylinder SSA50X30SB
The AirTAC Airtac SSA Single-Acting Compact Cylinder SSA50X30SB is a genuine single-acting COMPACT cylinder (single acting, push type) with a Ø50mm 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 SSA50X30SB
The AirTAC SSA50X30SB is a compact single-acting push-type cylinder where air pressure extends the rod and an internal spring retracts it. At 50 mm bore, it generates 874.7 N of net push force at 0.5 MPa, with the return spring counterforce already subtracted for precise sizing. A short riveted body minimizes axial mounting depth in crowded machinery.
This specific configuration includes a built-in piston magnet for AirTAC reed or electronic switches, plus a male M18x1.5 threaded rod end. End-of-stroke deceleration relies on a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion. Operating speed ranges from 50-500 mm/s.
Airtac SSA Single-Acting Compact Cylinder SSA50X30SB Technical Specifications
| Model | Airtac SSA Single-Acting Compact Cylinder SSA50X30SB |

| 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 |

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 (Ø50mm, Push)
| Pressure | Push force (net) |
|---|---|
| 0.5 MPa | 875 N |
| 0.7 MPa | 1267 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 SSA50X30SB Is Used
Heavy-Duty Stamping Ejector
Ejects formed metal parts from a die using the full 874.7 N net push, with the 30 mm stroke clearing the press bed quickly.
Pneumatic Riveting Clamp
Holds heavy structural plates in alignment for riveting, utilizing the male M18x1.5 rod end to secure custom clamping jaws.
Pallet Diverter Arm
Pushes loaded pallets onto a secondary conveyor line, where the compact riveted body saves valuable axial space along the belt.
Is the Airtac SSA Single-Acting Compact Cylinder SSA50X30SB the Right Cylinder?
When sizing this model, compare its 874.7 N net push at 0.5 MPa against adjacent bores: stepping down to SSA40 yields 545.6 N, while stepping up to SSA63 provides 1382.6 N. This SSA50X30SB variant features the maximum standard stroke of 30 mm, a PT1/4 port, the -S magnet option, and the -B male rod thread (M18x1.5). Keep in mind the internal spring actively drives the rod back to rest upon air loss, meaning it cannot hold a mid-stroke load without external live pressure or a locking device.
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 SSA50X30SB FAQ
The net push force is 874.7 N at 0.5 MPa and 1267.4 N at 0.7 MPa. These figures already account for the internal return spring, representing the actual usable output force.
Yes, it requires a minimum operating pressure of 0.2 MPa to overcome the internal return spring. Because it is single-acting push type, air extends the rod while the spring retracts it, and it cannot hold a mid-stroke load without live pressure.
