Airtac SSA Single-Acting Compact Cylinder SSA50X30
The AirTAC Airtac SSA Single-Acting Compact Cylinder SSA50X30 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 SSA50X30
The AirTAC SSA50X30 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, this 50 mm bore unit generates 874.7 N of net push force, which already accounts for the return spring resistance. Reaching the maximum standard stroke of 30 mm, it provides substantial extension capability for a riveted-body design.
This model features a 20 mm piston rod and a PT1/4 port. Because it requires just one air line and one solenoid valve port to drive the motion, plumbing is drastically simplified compared to double-acting alternatives. The short body length saves valuable axial mounting depth in crowded fixtures, and a fixed NBR bumper absorbs the end-of-stroke shock without requiring adjustment.
Airtac SSA Single-Acting Compact Cylinder SSA50X30 Technical Specifications

| 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 SSA50X30 Is Used
Heavy-Duty Stamping
Provides 874.7 N of net extension force at 0.5 MPa to press small components into machined housings within a 30 mm travel range.
Pallet Diverter
Uses the single-air-line simplicity to extend and push heavy pallets off a main transport line, relying on the internal spring to retract clear of the moving belt.
Carton Ejector
Leverages the compact riveted body to fit between tight conveyor rollers, ejecting packaged goods at the end of a packaging cycle.
Is the Airtac SSA Single-Acting Compact Cylinder SSA50X30 the Right Cylinder?
When sizing this model, consider the neighboring bores to match your exact load requirements. Stepping down to the SSA40 yields 545.6 N of net push at 0.5 MPa, while stepping up to the SSA63 provides 1382.6 N at the same pressure. For the SSA50X30, a safe working load is approximately 525 N, representing about 60 percent of the 874.7 N figure at 0.5 MPa, which translates to a vertical lift capacity of roughly 44.6 kg with a 2:1 safety margin.
This configuration uses a 30 mm stroke, which is the absolute maximum standard stroke for the SSA series. The operating pressure spans 0.2 to 1.0 MPa, requiring at least 0.2 MPa to overcome the internal spring. This specific SKU lacks the S magnet option, meaning it cannot support reed or electronic switches. The rod-end thread is female M10x1.5 by default, with a male M18x1.5 thread available via the B option. Remember that the spring actively drives the rod back to rest upon air loss, so it cannot hold a mid-stroke load without external mechanical locking.
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 SSA50X30 FAQ
The SSA50X30 delivers 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 the true usable output for your design calculations.
No, the internal spring drives the rod back to its retracted rest position when air pressure is released or falls below the 0.2 MPa minimum. It cannot hold a mid-stroke load; you would need an external rod lock or a double-acting SDA cylinder for position holding.
