Airtac STA Single Acting Compact Guided Cylinder STA32X30S
The AirTAC Airtac STA Single Acting Compact Guided Cylinder STA32X30S is a genuine single-acting COMPACT cylinder (single acting, pull type) with a Ø32mm 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 STA32X30S
The AirTAC STA32X30S is a compact single-acting pull-type cylinder where compressed air retracts the 12 mm rod and an internal spring extends it back out. At 0.5 MPa it generates 290.1 N of net pull, already accounting for the spring force. This makes it ideal for tensioning or pulling loads inward rather than pushing them.
Because it uses a short riveted body, this unit saves valuable axial mounting depth where a longer cylinder would not fit. It relies on a fixed NBR bumper to decelerate at the stroke end rather than an adjustable cushion. The built-in -S magnet allows position detection using an AirTAC reed or electronic switch.
Airtac STA Single Acting Compact Guided Cylinder STA32X30S Technical Specifications
| Model | Airtac STA Single Acting Compact Guided Cylinder STA32X30S |
|---|---|
| Series | STA compact single-acting cylinder |
| Bore size | Ø32 mm |
| Stroke | 30 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.

| STA | Compact single acting, pull type cylinder series. |
|---|---|
| 32 | Bore size in mm. |
| ×30 | 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 STA32X30S Is Used
Gate Retraction
Uses the 290.1 N net pull at 0.5 MPa to draw a diverter gate inward on a conveyor line, letting the spring push it back to the open position when air is cut.
Film Tensioning
Maintains steady tension on packaging film by pulling the idler roll back against the web, with the internal spring providing consistent extension force.
Lift and Lower
Handles a safe working load of roughly 174 N (about 60% of the 0.5 MPa rating) for lowering a light vertical fixture, achieving a vertical lift of approximately 14.8 kg with a 2:1 margin.
Is the Airtac STA Single Acting Compact Guided Cylinder STA32X30S the Right Cylinder?
When sizing this 32 mm bore model, consider the neighboring options. If your task requires less force, the STA25 provides 177.7 N net pull at 0.5 MPa. If you need more power, stepping up to the STA40 yields 445.1 N at 0.5 MPa. This STA32X30S configuration reaches the 30 mm maximum standard stroke ceiling for the series.
Keep in mind the spring-extend behavior: on air loss the rod drives to its extended rest position and will not hold a mid-stroke load. This specific build includes the S magnet for sensing and features a female M6x1.0 rod-end thread with a PT1/8 port. Operating pressure must be 0.2-1.0 MPa to overcome the spring.
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 STA32X30S FAQ
The net pull force is 290.1 N at 0.5 MPa and 428.3 N at 0.7 MPa. These values already have the return spring force subtracted, so you can size directly to these numbers.
Air pressure retracts the rod while an internal spring extends it. You need a minimum of 0.2 MPa operating pressure to overcome the spring. The included -S magnet works with AirTAC reed or electronic switches for end-position detection.
