Airtac STA Single Acting Compact Guided Cylinder STA32X30SB
The AirTAC Airtac STA Single Acting Compact Guided Cylinder STA32X30SB 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 STA32X30SB
The AirTAC STA32X30SB is a compact single-acting pull-type cylinder where compressed air retracts the 12 mm rod and an internal spring pushes it back out. It yields 290.1 N of net pull at 0.5 MPa, reaching 428.3 N at 0.7 MPa. This short 30 mm stroke variant utilizes a riveted body to minimize axial mounting depth where standard round-body or profile cylinders cannot fit.
This specific configuration includes a built-in piston magnet for position sensing along with a male M10x1.25 rod thread. The fixed NBR bumper decelerates the stroke end but does not act as an adjustable air cushion. A minimum operating pressure of 0.2 MPa is required to overcome the internal return spring.

| 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 |

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 STA32X30SB Is Used
Conveyor Diverter Gate
Applies 290.1 N of pulling force to retract a routing flap and relies on the internal spring to automatically reopen the gate when air pressure drops.
Carton Hold-Down Clamp
Uses the male M10x1.25 rod thread to secure a custom clamp, pulling packaging materials tight against a fixture during automated sealing cycles.
Storage Lane Stopper
Employs the spring-extend function to keep a pallet lane barrier normally raised, requiring 0.2 MPa of air pressure to pull the 12 mm rod down and release the load.
Is the Airtac STA Single Acting Compact Guided Cylinder STA32X30SB the Right Cylinder?
When sizing this 32 mm bore option, consider the STA25 which offers 177.7 N net pull at 0.5 MPa, or step up to the STA40 providing 445.1 N at 0.5 MPa. Operating pressure spans 0.2-1.0 MPa. With a 2:1 safety margin, the safe working load is approximately 174 N, allowing a vertical lift capacity of about 14.8 kg.
The 30 mm stroke represents the maximum standard limit for this series. Because the spring constantly drives the rod to the extended position, the STA32X30SB will not hold a mid-stroke load without live air pressure. This model features a PT1/8 port, the -S magnet for reed or electronic switches, and the -B male M10x1.25 rod end.
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 STA32X30SB FAQ
The net pull force is 290.1 N at 0.5 MPa and 428.3 N at 0.7 MPa. It requires an operating pressure between 0.2 MPa and 1.0 MPa, with a minimum of 0.2 MPa needed to overcome the return spring.
Air retracts the rod while the internal spring extends it, meaning the cylinder fails to the extended position on air loss and cannot hold a mid-stroke load. The built-in -S magnet allows tracking with either reed or electronic switches.
