Airtac STA Single Acting Compact Guided Cylinder STA63X30S
The AirTAC Airtac STA Single Acting Compact Guided Cylinder STA63X30S is a genuine single-acting COMPACT cylinder (single acting, pull type) with a Ø63mm 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 STA63X30S
The AirTAC STA63X30S is a 63 mm bore compact single-acting pull-type cylinder. Compressed air entering the PT1/4 port retracts the 20 mm rod, while an internal spring extends it when pressure drops. This normally-extended unit yields 1225.5 N of net pull at 0.5 MPa, making it highly effective for heavy tensioning and return-to-open duties.
Its short riveted body drastically cuts axial mounting depth compared to round-body alternatives. The 30 mm stroke represents the maximum standard travel for this series. Outfitted with a built-in piston magnet, the unit supports AirTAC reed or electronic switches for position sensing. End-of-stroke impact is managed by a fixed NBR bumper rather than an adjustable cushion.

| 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 |

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 STA63X30S Is Used
Heavy Gate Closing
Applies up to 1786.2 N of pulling force at 0.7 MPa to draw heavy industrial gates shut, relying on the spring to push them open safely during air loss.
Vertical Load Retraction
Pulls a 62.5 kg vertical load with a 2:1 safety margin, utilizing the 1225.5 N net pull at 0.5 MPa to lower materials into a resting cradle.
Press Hold-Down
Secures heavy sheet metal during stamping by pulling a clamp tight, where the compact riveted body fits into tight press tooling envelopes.
Is the Airtac STA Single Acting Compact Guided Cylinder STA63X30S the Right Cylinder?
When sizing this model, compare its 1225.5 N net pull at 0.5 MPa against adjacent bores. Stepping down, the STA50 provides 717.7 N, which may be insufficient for heavy gate-close applications. Because the STA63X30S sits at the top of the single-acting range, no larger bore exists for higher force requirements.
Remember the 30 mm stroke ceiling and the spring-extend behavior. The spring drives the rod out upon air loss, meaning it will not hold a mid-stroke load without an external locking device. This specific configuration includes the S magnet code for sensing and a female M10x1.5 rod-end thread. Operating pressure must be 0.2-1.0 MPa to overcome the spring.
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 STA63X30S FAQ
The STA63X30S 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, giving you the true usable pulling output.
No. As a single-acting pull-type cylinder, the internal spring extends the rod to its rest position when air is released. It cannot hold a mid-stroke load pneumatically and requires at least 0.2 MPa of air pressure to overcome the spring and retract.
