Airtac STA Single Acting Compact Guided Cylinder STA63X10S
The AirTAC Airtac STA Single Acting Compact Guided Cylinder STA63X10S is a genuine single-acting COMPACT cylinder (single acting, pull type) with a Ø63mm 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 STA63X10S
The AirTAC STA63X10S is a 63 mm bore compact single-acting pull-type cylinder where compressed air retracts the rod and an internal spring extends it out. It generates 1225.5 N of net pull at 0.5 MPa, making it suitable for heavy-duty tensioning within a short riveted body that saves axial mounting depth.
This unit includes a built-in piston magnet for position sensing with AirTAC reed or electronic switches. Operating pressure ranges from 0.2 to 1.0 MPa, requiring at least 0.2 MPa to overcome the internal spring, and end-of-stroke deceleration is handled by a fixed NBR bumper.
Airtac STA Single Acting Compact Guided Cylinder STA63X10S Technical Specifications
| Model | Airtac STA Single Acting Compact Guided Cylinder STA63X10S |
|---|---|
| Series | STA compact single-acting cylinder |
| Bore size | Ø63 mm |
| Stroke | 10 mm |
| Acting type | Single acting, pull type |
| Port size | PT1/4 |
| Rod end thread | M10×1.5 female / M18×1.5 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 (Ø63mm, Pull)
| Pressure | Pull force (net) |
|---|---|
| 0.5 MPa | 1226 N |
| 0.7 MPa | 1786 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 STA63X10S Is Used
Heavy-Duty Tensioning
Uses the 1225.5 N net pull at 0.5 MPa to draw heavy straps or belts tight, with the internal spring releasing tension when air is removed.
Pallet Gate Return
Employs the spring-extend function to push a loading gate open at rest, while air retracts the 20 mm rod to clear the path for forklift entry.
Stamping Pin Extraction
Pulls a 10 mm stroke to extract heavy locating pins from metal stamping dies, relying on the fixed NBR bumper to absorb the end shock.
Is the Airtac STA Single Acting Compact Guided Cylinder STA63X10S the Right Cylinder?
When sizing this model, the STA63X10S provides 1225.5 N net pull at 0.5 MPa and 1786.2 N at 0.7 MPa. Sizing downward, the STA50 bore offers 717.7 N at 0.5 MPa, meaning you step up to this 63 mm bore when the 50 mm falls short. The 10 mm stroke respects the 30 mm maximum standard limit for the series.
Because the spring extends the rod on air loss, this cylinder does not hold a mid-stroke load without live pressure. Confirm the PT1/4 port, the 20 mm rod diameter, the female M10x1.5 rod-end thread, and the -S magnet option for your sensing requirements.
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 STA63X10S FAQ
The STA63X10S delivers a net pull force of 1225.5 N at 0.5 MPa and 1786.2 N at 0.7 MPa. These figures already account for the internal return spring force, so you can size directly to these values.
Air pressure retracts the rod, and you need a minimum of 0.2 MPa to overcome the internal spring. When air is released, the spring extends the rod back out, meaning it fails to the extended position and will not hold a mid-stroke load.
