Airtac STA Single Acting Compact Guided Cylinder STA32X15B
The AirTAC Airtac STA Single Acting Compact Guided Cylinder STA32X15B is a genuine single-acting COMPACT cylinder (single acting, pull type) with a Ø32mm bore and 15mm 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 STA32X15B
The AirTAC STA32X15B is a compact single-acting pull-type cylinder. Air pressure retracts the 12mm rod, while an internal spring extends it to rest. It delivers 290.1 N of net pull at 0.5 MPa, with the spring force already subtracted. The short riveted body saves axial mounting depth where round-body cylinders fail.
This specific SKU features a male M10x1.25 rod-end thread. A fixed NBR bumper decelerates the stroke end, as it lacks adjustable air cushions. With no piston magnet, it cannot accept reed or electronic switches.
Airtac STA Single Acting Compact Guided Cylinder STA32X15B Technical Specifications
| Model | Airtac STA Single Acting Compact Guided Cylinder STA32X15B |
|---|---|
| Series | STA compact single-acting cylinder |
| Bore size | Ø32 mm |
| Stroke | 15 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.

Where the Airtac STA Single Acting Compact Guided Cylinder STA32X15B Is Used
Gate Retraction
Uses the 290.1 N pull to draw a diverter gate closed, relying on the internal spring to push it open if air pressure drops.
Film Tensioning
Maintains steady tension on packaging film by pulling the 12mm rod back against the load, saving axial space.
Carton Hold-Down
Pulls a hold-down bracket securely over a carton during labeling, with the male M10x1.25 thread ensuring a solid mount.
Is the Airtac STA Single Acting Compact Guided Cylinder STA32X15B the Right Cylinder?
Size by net pull: the STA25 yields 177.7 N at 0.5 MPa, while the STA40 yields 445.1 N. This 32mm bore provides a safe working load of roughly 174 N, allowing a vertical lift of about 14.8 kg with a 2:1 margin. Operating pressure is 0.2-1.0 MPa, needing at least 0.2 MPa to overcome the spring.
Confirm the 15mm stroke is within the 30mm maximum. The air port is PT1/8. This SKU includes the male M10x1.25 rod thread (-B) and no magnet. The spring extends the rod on air loss, so it cannot hold a mid-stroke load without 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 STA32X15B FAQ
It provides a net pull of 290.1 N at 0.5 MPa and 428.3 N at 0.7 MPa. These figures are already net of the return spring force.
Air retracts the rod, while the internal spring extends it. It requires at least 0.2 MPa to overcome the spring. On air loss, the spring drives the rod out to the extended position.
