Airtac STA Single Acting Compact Guided Cylinder STA63X10B
The AirTAC Airtac STA Single Acting Compact Guided Cylinder STA63X10B 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 STA63X10B
The AirTAC STA63X10B is a compact single-acting pull-type cylinder where compressed air retracts the rod and an internal spring extends it back out. It generates 1225.5 N of net pull at 0.5 MPa, reaching 1786.2 N at 0.7 MPa, with the return spring force already subtracted from the pneumatic effort.
Featuring a 63 mm bore and a 10 mm stroke, this riveted-body unit saves axial mounting depth compared to round-body alternatives. It uses a fixed NBR bumper to decelerate the stroke end and requires at least 0.2 MPa operating pressure to overcome the internal spring. This -B variant features a male M18x1.5 piston rod thread.
Airtac STA Single Acting Compact Guided Cylinder STA63X10B Technical Specifications
| Model | Airtac STA Single Acting Compact Guided Cylinder STA63X10B |
|---|---|
| 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 STA63X10B Is Used
Heavy-Duty Tensioning
Pulls heavy cables or webs with up to 1225.5 N net force at 0.5 MPa, relying on the internal spring to maintain baseline tension when air is removed.
Pallet Gate Return
Utilizes the 10 mm stroke to retract and hold a safety gate open, allowing the spring to automatically snap the barrier shut during an air supply failure.
Vertical Load Lifting
Lifts a 62.5 kg vertical load with a 2:1 safety margin, pulling the mass upward against gravity before the spring pushes it back down.
Is the Airtac STA Single Acting Compact Guided Cylinder STA63X10B the Right Cylinder?
When sizing this 63 mm bore actuator, stepping down to the STA50 yields 717.7 N of net pull at 0.5 MPa, while this STA63X10B provides 1225.5 N at the same pressure. The safe working load is approximately 735 N, offering a 2:1 margin for a vertical lift of roughly 62.5 kg. The 10 mm stroke sits well below the 30 mm single-acting ceiling.
Because the spring drives the rod out upon air loss, this cylinder cannot hold a mid-stroke load without live pressure. This specific SKU lacks a piston magnet, so position sensing is unavailable unless you move to an -S variant. Confirm the PT1/4 port, the male M18x1.5 rod thread, and the 50-500 mm/s speed range for your setup.
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 STA63X10B FAQ
The STA63X10B 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 opposing force of the internal return spring.
No, this specific SKU does not include a piston magnet. To use AirTAC reed or electronic switches, you must select the -S variant of this bore size.
