Airtac SSA Single-Acting Compact Cylinder SSA50X30B
The AirTAC Airtac SSA Single-Acting Compact Cylinder SSA50X30B 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 SSA50X30B
The AirTAC SSA50X30B is a compact single-acting push-type cylinder where air pressure extends the rod and an internal mechanical spring handles the retraction. Operating at 0.5 MPa, it generates 874.7 N of net push force, which already accounts for the spring resistance. The short riveted body design significantly reduces axial mounting depth, making it highly effective for fitting into densely packed machinery where standard length actuators fail to fit.
This specific configuration features a 30 mm stroke and a 50 mm bore with a male M18x1.5 piston rod thread. A single air line and one solenoid port drive the motion, which simplifies plumbing and lowers valve costs. End-of-stroke impact is managed by a fixed NBR bumper that decelerates the piston, rather than an adjustable air cushion.
Airtac SSA Single-Acting Compact Cylinder SSA50X30B Technical Specifications
| Model | Airtac SSA Single-Acting Compact Cylinder SSA50X30B |
|---|---|
| Series | SSA compact single-acting cylinder |
| Bore size | Ø50 mm |
| Stroke | 30 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 (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 SSA50X30B Is Used
Heavy-Duty Stamping Press
Applies 874.7 N of net force at 0.5 MPa to seat or stamp components securely within a 30 mm travel distance.
Pallet Ejection Station
Uses the male M18x1.5 rod thread to push loaded pallets off a conveyor line, saving axial space in tight transfer zones.
Rigid Clamping Fixture
Holds heavy workpieces firmly in place during machining, relying on the 50 mm bore power and fixed NBR bumper to absorb shock.
Is the Airtac SSA Single-Acting Compact Cylinder SSA50X30B the Right Cylinder?
When sizing this model, compare its 874.7 N net push at 0.5 MPa against adjacent bores: the SSA40 provides 545.6 N, while the SSA63 offers 1382.6 N. A practical safe working load is approximately 525 N, representing about 60 percent of the 0.5 MPa figure, which allows for a vertical lift capacity of roughly 44.6 kg with a 2:1 safety margin. The 30 mm stroke represents the maximum standard limit for this series.
This SKU includes the B option for a male-threaded M18x1.5 rod end and uses a PT1/4 port. Because it lacks the S option, there is no piston magnet, meaning it cannot support reed or electronic switches. Remember that the spring actively retracts the rod upon air loss; it will not hold a mid-stroke load without live pressure or an external 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 SSA50X30B FAQ
This model provides a net push force of 874.7 N at 0.5 MPa and 1267.4 N at 0.7 MPa. These figures already subtract the return spring resistance, giving you a true design value for your application.
No, the internal spring drives the rod back to its retracted rest position when air is released. It requires a minimum of 0.2 MPa to overcome the spring and cannot hold a mid-stroke load without external mechanical locking.
