Airtac SSA Single-Acting Compact Cylinder SSA16X30S
The AirTAC Airtac SSA Single-Acting Compact Cylinder SSA16X30S is a genuine single-acting COMPACT cylinder (single acting, push type) with a Ø16mm 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 SSA16X30S
The AirTAC SSA16X30S is a compact single-acting push-type cylinder where air pressure extends the rod and an internal mechanical spring retracts it. At 0.5 MPa it generates 80.5 N of net push output, meaning the return spring force is already subtracted from the raw air pressure. This 16 mm bore unit uses a 6 mm piston rod and features a built-in magnetic piston for position sensing.
Because the spring handles the return stroke, you only need a single air line and one solenoid port to drive the motion, reducing fitting complexity and saving valuable manifold space. The short riveted body minimizes axial mounting depth in tight fixtures, while a fixed NBR bumper absorbs end-of-stroke shock without requiring adjustment. Operating speed ranges from 50-500 mm/s across a 0.2-1.0 MPa pressure range.
Airtac SSA Single-Acting Compact Cylinder SSA16X30S Technical Specifications

| Acting type | Single acting, push type |
| Port size | M5×0.8 |
| Rod end thread | M3×0.5 female / M5×0.8 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 (Ø16mm, Push)
| Pressure | Push force (net) |
|---|---|
| 0.5 MPa | 81 N |
| 0.7 MPa | 121 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 SSA16X30S Is Used
Small Part Ejection
Uses the 80.5 N net push force to positively eject small stamped metal components from a die, with the spring ensuring safe retraction in tight tooling spaces.
Package Diverter
Employs the 30 mm stroke to push lightweight cartons off a conveyor belt, requiring only a single solenoid port to simplify the pneumatic manifold layout.
PCB Clamping Fixture
Secures delicate circuit boards during assembly using the 16 mm bore, relying on the compact riveted body to fit within densely packed electronic test stations.
Is the Airtac SSA Single-Acting Compact Cylinder SSA16X30S the Right Cylinder?
When sizing this model, consider the neighboring bores: stepping down to the SSA12 yields 46.5 N net push at 0.5 MPa, while stepping up to the SSA20 provides 134.1 N at the same pressure. This SSA16X30S provides a safe working load of roughly 48 N, or a vertical lift capacity of about 4.1 kg with a 2:1 safety margin. The 30 mm stroke represents the maximum standard limit for this series.
Remember that upon air loss or pressure release, the internal spring drives the rod back to its retracted rest position; it cannot hold a mid-stroke load without live pressure. This specific configuration includes the S option for a piston magnet compatible with AirTAC reed or electronic switches, and uses a female M3x0.5 rod-end thread with an M5x0.8 port.
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 SSA16X30S FAQ
The SSA16X30S provides 80.5 N of net push force at 0.5 MPa and 120.7 N at 0.7 MPa. These figures already account for the internal return spring resistance, giving you the true usable output force for your design calculations.
No, it cannot hold a mid-stroke load. As a single-acting push cylinder, the internal spring drives the rod back to its retracted position when air pressure drops below the 0.2 MPa minimum. For load holding without live pressure, a double-acting cylinder with an external rod lock is required.
