Airtac SSA Single-Acting Compact Cylinder SSA16X15
The AirTAC Airtac SSA Single-Acting Compact Cylinder SSA16X15 is a genuine single-acting COMPACT cylinder (single acting, push type) with a Ø16mm bore and 15mm 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 SSA16X15
The AirTAC SSA16X15 is a compact single-acting push-type cylinder where air pressure extends the rod and an internal spring retracts it. It generates 80.5 N of net push at 0.5 MPa, meaning the return spring force is already subtracted from the raw air force. This 16 mm bore actuator uses a short riveted body to minimize axial mounting depth in crowded fixtures.
Because it requires just one air line and one solenoid port, plumbing is greatly simplified. The fixed NBR bumper decelerates the stroke end but is not an adjustable cushion. This specific SKU lacks a piston magnet, so it cannot accept position switches without upgrading to the -S variant.
Airtac SSA Single-Acting Compact Cylinder SSA16X15 Technical Specifications
| Model | Airtac SSA Single-Acting Compact Cylinder SSA16X15 |
|---|---|
| Series | SSA compact single-acting cylinder |
| Bore size | Ø16 mm |
| Stroke | 15 mm |
| 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.

Thread: PT standard. SSA pushes out / spring returns; STA pulls in / spring extends. Related: SDA (double acting), SDAD (double rod), SDAJ (adjustable stroke).
Where the Airtac SSA Single-Acting Compact Cylinder SSA16X15 Is Used
Small Part Ejection
Uses the 80.5 N net push to eject lightweight molded components from a tight fixture before the next cycle.
Package Diverting
Extends 15 mm to push small cartons off a narrow belt, relying on the internal spring to retract instantly.
Bin Lid Actuation
Pops a hopper lid open on command, with the short riveted body fitting into restricted machinery frames.
Is the Airtac SSA Single-Acting Compact Cylinder SSA16X15 the Right Cylinder?
When sizing this model, compare its 80.5 N net push at 0.5 MPa against adjacent bores. Stepping down to the SSA12 yields 46.5 N, while stepping up to the SSA20 provides 134.1 N. A safe working load is roughly 48 N, allowing a vertical lift of about 4.1 kg with a 2:1 safety margin.
This 16 mm bore unit features a 15 mm stroke, well within the 30 mm maximum. It requires a minimum operating pressure of 0.2 MPa to overcome the spring. If air is lost, the spring drives the rod back to rest; it cannot hold a mid-stroke load. Confirm your bore, stroke, M5x0.8 port, female M3x0.5 rod thread, and that no magnet is needed.
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 SSA16X15 FAQ
The net push force is 80.5 N at 0.5 MPa and 120.7 N at 0.7 MPa. These figures already account for the internal return spring resistance.
No. The internal spring drives the rod to its retracted rest position upon air loss. It cannot hold a mid-stroke load and requires at least 0.2 MPa to overcome the spring.
