Airtac STA Single Acting Compact Guided Cylinder STA16X30S
The AirTAC Airtac STA Single Acting Compact Guided Cylinder STA16X30S is a genuine single-acting COMPACT cylinder (single acting, pull type) with a Ø16mm bore and 30mm 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 STA16X30S
The AirTAC STA16X30S is a compact single-acting pull-type cylinder where air retracts the 6 mm rod and an internal spring extends it back out. It provides 66.4 N of net pull at 0.5 MPa and 101 N at 0.7 MPa, making it suitable for light-duty tensioning and hold-down operations.
This unit features a built-in piston magnet for position sensing with AirTAC reed or electronic switches. Its short riveted body saves valuable axial mounting depth in tight spaces, and a fixed NBR bumper handles end-of-stroke deceleration without needing adjustable cushions.
Airtac STA Single Acting Compact Guided Cylinder STA16X30S Technical Specifications
| Model | Airtac STA Single Acting Compact Guided Cylinder STA16X30S |
|---|---|
| Series | STA compact single-acting cylinder |
| Bore size | Ø16 mm |
| Stroke | 30 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.

Where the Airtac STA Single Acting Compact Guided Cylinder STA16X30S Is Used
Film Web Tensioning
Applies a steady 66.4 N pull at 0.5 MPa to maintain tension on packaging film webs, with the spring safely returning the roller arm when air is removed.
Pallet Gate Return
Uses the spring-extend function to push a conveyor diverter gate back to its open resting state after compressed air retracts the rod to clear passing packages.
Carton Flap Hold-Down
Pulls a holding bracket down out of the way during box erection, saving axial space while the internal spring reliably resets the mechanism for the next cycle.
Is the Airtac STA Single Acting Compact Guided Cylinder STA16X30S the Right Cylinder?
When sizing this 16 mm bore actuator, consider the neighboring options: the STA12 yields 32.4 N at 0.5 MPa, while the larger STA20 provides 108.9 N. This STA16X30S offers a safe working load of roughly 40 N, or a vertical lift capacity of about 3.4 kg with a 2:1 safety margin.
This model uses a 30 mm stroke, which is the maximum standard length for the series. It requires at least 0.2 MPa of operating pressure to overcome the return spring. Because the spring drives the rod to its extended rest position on air loss, it will not hold a mid-stroke load without external locking. The configuration includes an M5x0.8 port, a female M3x0.5 rod-end thread, and the -S magnet option.
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 STA16X30S FAQ
The net pull force is 66.4 N at 0.5 MPa and 101 N at 0.7 MPa. These values already account for the internal return spring, so you can size directly to these figures.
No. As a single-acting pull-type cylinder, the spring drives the rod to its extended rest position when air is lost. It requires at least 0.2 MPa to overcome the spring and will not hold a mid-stroke load without an external rod lock.
