Airtac STA Single Acting Compact Guided Cylinder STA32X30B
The AirTAC Airtac STA Single Acting Compact Guided Cylinder STA32X30B 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 STA32X30B
The AirTAC STA32X30B is a compact single-acting pull-type cylinder where compressed air retracts the rod and an internal spring extends it back out. It yields 290.1 N of net pull at 0.5 MPa, reaching 428.3 N at 0.7 MPa. Because the spring handles the extension stroke, you only need one air line connected to its PT1/8 port.
This specific SKU features a male M10x1.25 thread on its 12 mm piston rod for direct load attachment. The short riveted body drastically reduces axial mounting depth compared to round-body alternatives. End-of-stroke energy is managed strictly by a fixed NBR bumper, which decelerates the motion but is not an adjustable cushion.

| 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 STA32X30B Is Used
Tensioning Systems
Uses the 290.1 N pull force to draw back belts or filaments, relying on the spring to automatically slacken the line when air pressure drops.
Hold-Down Clamps
Pulls a male M10x1.25 threaded clamp pin down to secure parts, with the spring safely lifting the clamp to release the workpiece.
Gate Diverters
Retracts a sorting flap on a 30 mm stroke to redirect packages, letting the internal spring snap the diverter back to its open rest position.
Is the Airtac STA Single Acting Compact Guided Cylinder STA32X30B the Right Cylinder?
When sizing this 32 mm bore, verify if the adjacent options better fit your payload. Stepping down, the STA25 provides 177.7 N net pull at 0.5 MPa, while stepping up to the STA40 yields 445.1 N. At 0.5 MPa, this STA32X30B offers a safe working load of roughly 174 N (about 60 percent of its rated force), translating to a vertical lift capacity near 14.8 kg with a 2:1 safety margin.
This model utilizes the maximum standard stroke ceiling of 30 mm. It requires a minimum operating pressure of 0.2 MPa to overcome the internal spring. Since this unit lacks the -S suffix, it has no piston magnet and cannot accept reed or electronic switches. It carries the -B option, meaning the rod end is male M10x1.25 instead of the default female M6x1.0 thread.
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 STA32X30B 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, so they represent the actual usable pulling output.
Air pressure must be at least 0.2 MPa to overcome the spring and pull the rod in. When air is released, the spring drives the rod out to its extended rest position. It will not hold a mid-stroke load without live air pressure.
