Airtac STA Single Acting Compact Guided Cylinder STA32X5B
The AirTAC Airtac STA Single Acting Compact Guided Cylinder STA32X5B is a genuine single-acting COMPACT cylinder (single acting, pull type) with a Ø32mm 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 STA32X5B
The AirTAC STA32X5B is a compact single-acting pull-type cylinder where air retracts the rod and an internal spring extends it. It provides 290.1 N net pull at 0.5 MPa and 428.3 N at 0.7 MPa. The short riveted body saves axial mounting depth where a round-body cylinder will not fit.
This SKU features a male M10x1.25 piston rod and a PT1/8 port. It has no piston magnet, so it cannot accept magnetic switches. A fixed NBR bumper decelerates the stroke end, operating at 50-500 mm/s across a -20 to +70 C range.
Airtac STA Single Acting Compact Guided Cylinder STA32X5B Technical Specifications
| Model | Airtac STA Single Acting Compact Guided Cylinder STA32X5B |
|---|---|
| Series | STA compact single-acting cylinder |
| Bore size | Ø32 mm |
| Stroke | 5 mm |
| Acting type | Single acting, pull type |
| Port size | PT1/8 |
| Rod end thread | M6×1.0 female / M10×1.25 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 (Ø32mm, Pull)
| Pressure | Pull force (net) |
|---|---|
| 0.5 MPa | 290 N |
| 0.7 MPa | 428 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.

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 STA32X5B Is Used
Short-Stroke Tensioning
Uses the 290.1 N net pull to draw a belt or wire taut, with the internal spring relaxing the tension when air is cut.
Flap Hold-Down
Pulls a packaging guide out of the way during carton transit, relying on the spring to snap it back to the rest position.
Diverter Gate Return
Retracts a sorting gate via the male M10x1.25 rod to allow product flow, letting the spring push it closed as a failsafe.
Is the Airtac STA Single Acting Compact Guided Cylinder STA32X5B the Right Cylinder?
At 0.5 MPa this 32 mm bore yields 290.1 N net pull. Sizing both ways: the STA25 provides 177.7 N, while the STA40 offers 445.1 N. This makes the STA32X5B ideal for a safe working load around 174 N, giving a 2:1 margin for a 14.8 kg vertical lift.
The 5 mm stroke sits well under the 30 mm single-acting ceiling. Because the spring drives the rod out on air loss, it will not hold a mid-stroke load without live pressure. Confirm the male M10x1.25 rod, PT1/8 port, and the lack of a magnet for your sensing requirements.
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 STA32X5B FAQ
The single-acting pull force is 290.1 N at 0.5 MPa and 428.3 N at 0.7 MPa. These figures are already net of the return spring. It requires at least 0.2 MPa operating pressure to overcome the spring.
No, this specific SKU lacks the -S magnet option and cannot accept reed or electronic switches. The internal spring extends the rod on air loss, so it does not hold a mid-stroke load without live pressure.
