Airtac STA Single Acting Compact Guided Cylinder STA32X5SB
The AirTAC Airtac STA Single Acting Compact Guided Cylinder STA32X5SB 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 STA32X5SB
The AirTAC STA32X5SB is a compact single-acting pull-type cylinder where compressed air retracts the rod and an internal spring pushes it back out. It yields 290.1 N of net pull at 0.5 MPa, making it ideal for brief tensioning tasks. The short riveted body drastically cuts axial mounting depth where longer profile or round-body units cannot fit.
This specific configuration includes a built-in piston magnet for position sensing along with a male M10x1.25 rod end. End-of-stroke energy is absorbed by a fixed NBR bumper rather than an adjustable cushion. Operating pressure spans 0.2-1.0 MPa, requiring at least 0.2 MPa to overcome the return spring.
Airtac STA Single Acting Compact Guided Cylinder STA32X5SB Technical Specifications
| Model | Airtac STA Single Acting Compact Guided Cylinder STA32X5SB |
|---|---|
| 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.

Where the Airtac STA Single Acting Compact Guided Cylinder STA32X5SB Is Used
Tension Pull-Back
Uses the 290.1 N net pull to retract a tensioning cable or belt, relying on the internal spring to automatically slacken the line when air pressure drops.
Fail-Safe Gate Opening
Keeps a lightweight access hatch normally open via spring force, with air pressure pulling the 12 mm rod inward to close the barrier on demand.
Carton Flap Hold-Down
Pulls a short 5 mm lever arm to hold cardboard flaps clear during filling, releasing the mechanism instantly upon venting to speed up the packing line.
Is the Airtac STA Single Acting Compact Guided Cylinder STA32X5SB the Right Cylinder?
When sizing this unit, compare its 290.1 N net pull at 0.5 MPa against adjacent bores: the STA25 provides 177.7 N, while the STA40 offers 445.1 N. This yields a safe working load of roughly 174 N at a 2:1 margin, or a vertical lift capacity around 14.8 kg. The 5 mm stroke sits well under the 30 mm series ceiling.
Because the spring constantly drives the rod outward, this model cannot hold a mid-stroke load without live air pressure; utilize an external rod lock for static holding. This SKU confirms a 32 mm bore, PT1/8 port, -S magnet for reed or electronic switches, and the -B male threaded piston rod.
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 STA32X5SB FAQ
The single-acting pull force is already net of the return spring. It delivers 290.1 N at 0.5 MPa and 428.3 N at 0.7 MPa. You must supply at least 0.2 MPa to overcome the spring and initiate the retraction stroke.
No. The internal spring constantly extends the rod to its outward rest position. It does not lock or hold a mid-stroke load without live air. For secure mid-stroke holding, use a double-acting SDA cylinder paired with an external rod lock.
