Airtac STA Single Acting Compact Guided Cylinder STA16X25B
The AirTAC Airtac STA Single Acting Compact Guided Cylinder STA16X25B is a genuine single-acting COMPACT cylinder (single acting, pull type) with a Ø16mm bore and 25mm 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 STA16X25B
The AirTAC STA16X25B is a compact single-acting pull-type cylinder where compressed air retracts the rod and an internal spring pushes it back out. It provides 66.4 N of net pull at 0.5 MPa, meaning the spring resistance is already subtracted from the pneumatic force. This unit features a 25 mm stroke and a male M5x0.8 threaded rod end for direct load attachment.
Designed to save axial mounting depth, the short riveted body fits where longer profile cylinders cannot. The bore dictates the M5x0.8 air port, and a fixed NBR bumper decelerates the stroke ends rather than using an adjustable cushion. Operating speed ranges from 50-500 mm/s across a temperature span of -20 to +70 C.
Airtac STA Single Acting Compact Guided Cylinder STA16X25B Technical Specifications
| Model | Airtac STA Single Acting Compact Guided Cylinder STA16X25B |
|---|---|
| Series | STA compact single-acting cylinder |
| Bore size | Ø16 mm |
| Stroke | 25 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 STA16X25B Is Used
Tension Pull-Back
Uses the 66.4 N net pull to draw a tensioned cable or wire harness back to a home position when actuated.
Gate Retraction
Air retracts the 25 mm stroke to pull a lightweight diverter gate open, allowing the spring to snap it closed for sorting.
Film Hold-Down
Pulls a clamping arm out of the way during film wrapping, relying on the male M5x0.8 rod to secure the mechanism.
Is the Airtac STA Single Acting Compact Guided Cylinder STA16X25B the Right Cylinder?
When sizing this 16 mm bore, compare its 66.4 N net pull at 0.5 MPa against neighboring bores. Dropping down to the STA12 yields 32.4 N, while stepping up to the STA20 provides 108.9 N. A safe working load is approximately 40 N, allowing a vertical lift of about 3.4 kg with a 2:1 safety margin.
This SKU lacks the S magnet code, so it cannot accept reed or electronic switches. It requires at least 0.2 MPa operating pressure to overcome the spring. Remember the 30 mm maximum standard stroke ceiling, and note that the spring drives the rod to its extended rest position on air loss without holding 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 STA16X25B 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 being subtracted from the pneumatic force.
No, this specific SKU lacks the S option code, meaning it has no piston magnet and cannot accept reed or electronic switches. You would need the STA16X25BS variant for sensing capabilities.
