Airtac STA Single Acting Compact Guided Cylinder STA32X10SB
The AirTAC Airtac STA Single Acting Compact Guided Cylinder STA32X10SB is a genuine single-acting COMPACT cylinder (single acting, pull type) with a Ø32mm bore and 10mm 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 STA32X10SB
The AirTAC STA32X10SB is a compact single-acting pull-type cylinder where compressed air retracts the rod and an internal spring pushes it back out. It generates 290.1 N of net pull at 0.5 MPa, making it highly effective for tensioning and hold-down tasks. The short riveted body saves valuable axial mounting depth in tight machinery.
This specific configuration includes a built-in piston magnet for position sensing along with a male M10x1.25 threaded rod end. It operates at 50-500 mm/s and relies on a fixed NBR bumper to decelerate the stroke end. You must supply at least 0.2 MPa of air pressure to overcome the return spring.
Airtac STA Single Acting Compact Guided Cylinder STA32X10SB Technical Specifications
| Model | Airtac STA Single Acting Compact Guided Cylinder STA32X10SB |
|---|---|
| Series | STA compact single-acting cylinder |
| Bore size | Ø32 mm |
| Stroke | 10 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 |

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 STA32X10SB Is Used
Film Web Tensioning
Pulls a tensioning idler roller back against packaging film webbing, using the 290.1 N net pull to maintain consistent material feed without drifting.
Pneumatic Hold-Down Clamp
Retracts a clamp pin to secure a workpiece during machining, relying on the internal spring to safely release the part to its open state.
Diverter Gate Return
Draws a sorting gate inward on actuation to divert packages on a conveyor, allowing the spring to snap the gate back to the default resting position.
Is the Airtac STA Single Acting Compact Guided Cylinder STA32X10SB the Right Cylinder?
When sizing this unit, verify that your load requires roughly 174 N of safe working pull, which represents about 60 percent of the 290.1 N available at 0.5 MPa. If you need less force, stepping down to the STA25 bore provides 177.7 N, while moving up to the STA40 yields 445.1 N. This 10 mm stroke sits well below the 30 mm series ceiling.
Because the spring constantly drives the rod to the extended position, this model cannot hold a mid-stroke load without live air pressure. Confirm your setup needs the male M10x1.25 rod thread, the PT1/8 port, and the -S magnet for reed or electronic switches. For powered clamping or load holding without continuous pressure, consider a double-acting SDA with an external lock.
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 STA32X10SB FAQ
The net pull force is 290.1 N at 0.5 MPa and 428.3 N at 0.7 MPa. These figures already account for the internal return spring resistance, meaning air pressure only pulls the load inward.
No, the spring constantly extends the rod when air is released, so it cannot maintain a mid-stroke position. It requires at least 0.2 MPa operating pressure to overcome the spring and pull the load, and an external rod lock is needed for holding without live air.
