Airtac STA Single Acting Compact Guided Cylinder STA16X5SB
The AirTAC Airtac STA Single Acting Compact Guided Cylinder STA16X5SB is a genuine single-acting COMPACT cylinder (single acting, pull type) with a Ø16mm bore and 5mm 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 STA16X5SB
The AirTAC STA16X5SB is a compact single-acting pull-type cylinder where air retracts the rod and an internal spring pushes it back out. It generates 66.4 N of net pull at 0.5 MPa, making it suitable for light tensioning duties. The short riveted body minimizes axial mounting depth in tight machinery.
This configuration includes a built-in piston magnet for AirTAC reed or electronic switches, plus a male M5x0.8 threaded rod end. A fixed NBR bumper decelerates the stroke end. With a safe working load around 40 N, it can vertically lift roughly 3.4 kg with a 2:1 margin.
Airtac STA Single Acting Compact Guided Cylinder STA16X5SB Technical Specifications
| Model | Airtac STA Single Acting Compact Guided Cylinder STA16X5SB |
|---|---|
| Series | STA compact single-acting cylinder |
| Bore size | Ø16 mm |
| Stroke | 5 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. |
| ×5 | 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 STA16X5SB Is Used
Tension Return
Pulls a light cable or belt with 66.4 N net force at 0.5 MPa, letting the internal spring automatically slacken it when air is removed.
Hold-Down Release
Retracts a 5 mm clamp pin to free a small workpiece, relying on the spring to re-engage the stop when the pneumatic signal drops.
Flap Closer
Draws a packaging guide back 5 mm against the 101 N pull at 0.7 MPa, allowing the spring to push the guide open for the next carton.
Is the Airtac STA Single Acting Compact Guided Cylinder STA16X5SB the Right Cylinder?
When sizing this 16 mm bore, stepping down to the STA12 yields 32.4 N net pull at 0.5 MPa, while stepping up to the STA20 provides 108.9 N. This STA16X5SB features a 5 mm stroke, well under the 30 mm single-acting ceiling.
Because the spring drives the rod out upon air loss, it will not hold a mid-stroke load without live pressure. Confirm your requirements for the M5x0.8 port, male rod thread, and the -S magnet option before ordering.
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 STA16X5SB FAQ
The net pull force is 66.4 N at 0.5 MPa and 101 N at 0.7 MPa. These figures already account for the internal return spring resistance.
No, the spring extends the rod at rest. It requires at least 0.2 MPa of air pressure to overcome the spring and retract the rod. It cannot hold a mid-stroke load without live pressure.
