Airtac STA Single Acting Compact Guided Cylinder STA63X10
The AirTAC Airtac STA Single Acting Compact Guided Cylinder STA63X10 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 STA63X10
The AirTAC STA63X10 is a 63 mm bore compact single-acting pull-type cylinder where compressed air retracts the rod and an internal spring pushes it back out. It generates 1225.5 N of net pull at 0.5 MPa and 1786.2 N at 0.7 MPa, with the spring force already subtracted from the pneumatic effort. This makes it highly effective for heavy-duty tensioning or pulling loads inward rather than pushing them.
The short riveted body saves axial mounting depth where a larger profile cylinder will not fit. It features a 20 mm piston rod, a PT1/4 air port, and a fixed NBR bumper that decelerates the stroke end without acting as an adjustable lock. This specific SKU lacks a piston magnet, so it cannot accept reed or electronic switches without upgrading to the -S variant.
Airtac STA Single Acting Compact Guided Cylinder STA63X10 Technical Specifications
| Model | Airtac STA Single Acting Compact Guided Cylinder STA63X10 |
|---|---|
| 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.

Thread: PT standard. SSA pushes out / spring returns; STA pulls in / spring extends. Related: SDA (double acting), SDAD (double rod), SDAJ (adjustable stroke).
Where the Airtac STA Single Acting Compact Guided Cylinder STA63X10 Is Used
Heavy-Duty Cable Tensioning
Utilizes the 1225.5 N net pull at 0.5 MPa to draw heavy cables or winch assemblies taut, relying on the internal spring to slacken the line when air pressure drops.
Industrial Clamp Retraction
Pulls a heavy workholding clamp out of the way during part ejection, using the 10 mm stroke to safely clear the machining zone before the spring extends it back.
Pallet Gate Closing
Applies robust pulling force to draw a loaded pallet gate inward, ensuring the barrier is securely held closed against heavy inventory during transit.
Is the Airtac STA Single Acting Compact Guided Cylinder STA63X10 the Right Cylinder?
When sizing this model, consider the neighboring bores to match your actual load requirements. Stepping down, the STA50 provides 717.7 N of net pull at 0.5 MPa, which is significantly less pulling power. The STA63X10 itself yields a safe working load of roughly 735 N, equating to a vertical lift capacity of about 62.5 kg with a 2:1 safety margin. Operating pressure must sit between 0.2 and 1.0 MPa, requiring at least 0.2 MPa to overcome the internal spring.
This configuration uses a 10 mm stroke, well under the 30 mm maximum ceiling for the series. Because the spring drives the rod to the extended position on air loss, it will not hold a mid-stroke load without live pressure or an external rod lock. Confirm your bore, stroke, PT1/4 port, and female M10x1.5 rod-end thread requirements before ordering.
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 STA63X10 FAQ
The STA63X10 provides 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 resistance, meaning the spring force has been subtracted from the raw pneumatic output.
No, this specific SKU does not include a piston magnet, so it cannot accept AirTAC reed or electronic switches. You would need to specify the -S option code to add a built-in magnet for switch mounting in the body sensor grooves.
