Airtac STA Single Acting Compact Guided Cylinder STA16X20
The AirTAC Airtac STA Single Acting Compact Guided Cylinder STA16X20 is a genuine single-acting COMPACT cylinder (single acting, pull type) with a Ø16mm bore and 20mm stroke. Air pulles 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 STA Single Acting Compact Guided Cylinder STA16X20
The AirTAC STA16X20 is a compact single-acting pull-type cylinder where air retracts the rod and an internal spring extends it back out. It provides 66.4 N of net pull at 0.5 MPa, making it suitable for tensioning and return-to-open tasks. Because the quoted force is already net of the spring, you can size directly to this 66.4 N value.
This actuator features a short riveted body that saves axial mounting depth where a standard round-body cylinder will not fit. It uses a fixed NBR bumper to decelerate the stroke end, which is not an adjustable air cushion. This specific SKU lacks a piston magnet, so it cannot accept a position switch.
Airtac STA Single Acting Compact Guided Cylinder STA16X20 Technical Specifications
| Model | Airtac STA Single Acting Compact Guided Cylinder STA16X20 |
|---|---|
| Series | STA compact single-acting cylinder |
| Bore size | Ø16 mm |
| Stroke | 20 mm |
| Acting type | Single acting, pull 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, Pull)
| Pressure | Pull force (net) |
|---|---|
| 0.5 MPa | 66 N |
| 0.7 MPa | 101 N |
These are NET output forces — the return-spring force is already deducted. Single-acting pull only; the spring performs the opposite stroke. Size with a safety margin.

| STA | Compact single acting, pull type cylinder series. |
|---|---|
| 16 | Bore size in mm. |
| ×20 | Stroke length in mm (single-acting max 30 mm). |
| S | Built-in magnet for magnetic-switch sensing (omit = none). |

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 STA Single Acting Compact Guided Cylinder STA16X20 Is Used
Wire Tensioning
Uses the 66.4 N net pull to maintain consistent tension on filaments during a winding cycle.
Flap Holding
Pulls a carton flap open against the internal spring, allowing adhesive application before release.
Gate Return
Air retracts the rod to open a diverter gate, and the spring automatically closes it upon air release.
Is the Airtac STA Single Acting Compact Guided Cylinder STA16X20 the Right Cylinder?
When sizing this 16 mm bore actuator, compare its 66.4 N net pull at 0.5 MPa against adjacent bores. Stepping down, the STA12 yields 32.4 N; stepping up, the STA20 provides 108.9 N. A safe working load is roughly 40 N, or a vertical lift of about 3.4 kg with a 2:1 margin.
This model has a 20 mm stroke, well under the 30 mm single-acting ceiling. It requires 0.2 to 1.0 MPa operating pressure to function. Confirm your bore, stroke, M5x0.8 port, female rod-end thread, and lack of a magnet. Remember the spring extends the rod on air loss, so it will not hold a mid-stroke load.
Quick checklist
- ✓ Net pull 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 STA Single Acting Compact Guided Cylinder STA16X20 FAQ
This cylinder provides a net pull of 66.4 N at 0.5 MPa and 101 N at 0.7 MPa. The spring force is already subtracted from these figures.
No, this specific SKU does not have the -S magnet code, so it cannot accept reed or electronic switches. You would need the STA16X20S variant for position sensing.
