Airtac STA Single Acting Compact Guided Cylinder STA16X15SB
The AirTAC Airtac STA Single Acting Compact Guided Cylinder STA16X15SB is a genuine single-acting COMPACT cylinder (single acting, pull type) with a Ø16mm bore and 15mm 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 STA16X15SB
The AirTAC STA16X15SB is a compact single-acting pull-type cylinder where compressed air retracts the 6 mm rod and an internal spring pushes it back out. It yields 66.4 N of net pull at 0.5 MPa, making it suitable for tensioning and return-to-open duties. Because the spring performs the extension stroke, only one M5x0.8 air line and a single solenoid port are required.
This thin riveted-body design saves axial mounting depth where a larger profile cylinder will not fit. The unit includes a built-in piston magnet for AirTAC reed or electronic switches and a male M5x0.8 rod thread. End-of-stroke energy is managed by a fixed NBR bumper, which decelerates the piston without locking the load in place.
Airtac STA Single Acting Compact Guided Cylinder STA16X15SB Technical Specifications
| Model | Airtac STA Single Acting Compact Guided Cylinder STA16X15SB |

| 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.

Where the Airtac STA Single Acting Compact Guided Cylinder STA16X15SB Is Used
Tensioning Levers
Pulls a linkage back to an open position with 66.4 N net force, using the internal spring to maintain tension when air is removed.
Gate Diversion
Retracts a sorting flap on a 15 mm stroke to let packages pass, relying on the compact riveted body to fit tight conveyor frames.
Hold-Down Release
Pulls a light clamping pin out of the way via the male M5x0.8 rod end so packaging materials can advance.
Is the Airtac STA Single Acting Compact Guided Cylinder STA16X15SB the Right Cylinder?
When sizing this 16 mm bore, compare its 66.4 N net pull at 0.5 MPa against adjacent models. Dropping down to the STA12 provides 32.4 N, while stepping up to the STA20 offers 108.9 N. A practical safe working load is roughly 40 N, allowing a vertical lift of about 3.4 kg with a 2:1 safety margin.
The 15 mm stroke sits well below the 30 mm maximum limit. Remember that the spring drives the rod to its extended rest position on air loss, so it cannot hold a mid-stroke load. This configuration confirms the 16 mm bore, 15 mm stroke, M5x0.8 port, -S magnet, and -B male M5x0.8 rod thread.
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 STA16X15SB FAQ
This cylinder provides 66.4 N of net pull at 0.5 MPa and 101 N at 0.7 MPa. These figures already account for the internal return spring resistance.
Air pressure retracts the rod, requiring at least 0.2 MPa to overcome the spring. When air is released, the spring extends the rod back out, meaning it will not hold a mid-stroke load without live pressure.
