Airtac STA Single Acting Compact Guided Cylinder STA32X20SB
The AirTAC Airtac STA Single Acting Compact Guided Cylinder STA32X20SB is a genuine single-acting COMPACT cylinder (single acting, pull type) with a Ø32mm bore and 20mm 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 STA32X20SB
The AirTAC STA32X20SB is a compact single-acting pull-type cylinder where compressed air retracts the 12 mm piston rod and an internal spring pushes it back out. It generates 290.1 N of net pull at 0.5 MPa, meaning the quoted force already subtracts the spring resistance. This makes it perfect for tensioning or pulling loads rather than pushing them.
Because it uses a short riveted body, this unit saves valuable axial mounting depth where standard round-body or larger profile cylinders cannot fit. It features a built-in piston magnet for position sensing and a male M10x1.25 rod thread. A fixed NBR bumper handles end-of-stroke deceleration, requiring just one air line and solenoid port for operation.
Airtac STA Single Acting Compact Guided Cylinder STA32X20SB Technical Specifications
| Model | Airtac STA Single Acting Compact Guided Cylinder STA32X20SB |

| 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.

Where the Airtac STA Single Acting Compact Guided Cylinder STA32X20SB Is Used
Tension Gate Control
Uses the 290.1 N net pull to retract and hold a diverter gate against product flow, letting the spring safely extend it open during an air loss.
Film Roll Tensioning
Maintains steady pulling tension on packaging web material, utilizing the male M10x1.25 rod thread for secure mechanical linkage.
Component Hold-Down
Pulls a locating pin out of the way via a single PT1/8 air line, allowing the internal spring to passively lock the pin during assembly rests.
Is the Airtac STA Single Acting Compact Guided Cylinder STA32X20SB the Right Cylinder?
When sizing this 32 mm bore model, compare its 290.1 N net pull at 0.5 MPa against adjacent bores. If your load is lighter, the STA25 provides 177.7 N; if heavier, the STA40 offers 445.1 N. This STA32X20SB configuration includes the S magnet for reed or electronic switches and the B option for a male M10x1.25 rod end, replacing the default female M6x1.0 thread.
The 20 mm stroke sits well below the 30 mm single-acting ceiling. Remember that the spring extends the rod when air is removed, so it will not hold a mid-stroke load without live pressure or an external lock. Operating pressure must be at least 0.2 MPa to overcome the return spring, with a speed range of 50-500 mm/s.
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 STA32X20SB FAQ
This cylinder provides a net pull force of 290.1 N at 0.5 MPa and 428.3 N at 0.7 MPa. It requires an operating pressure between 0.2 and 1.0 MPa, as a minimum of 0.2 MPa is needed to overcome the internal return spring.
Air pressure pulls the rod inward, while the internal spring pushes it back out when air is released. Because the spring drives the rod to its extended rest position on air loss, it cannot hold a mid-stroke load without external locking devices. The included S magnet works with AirTAC reed or electronic switches.
