Airtac STA Single Acting Compact Guided Cylinder STA63X30
The AirTAC Airtac STA Single Acting Compact Guided Cylinder STA63X30 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 STA63X30
The AirTAC STA63X30 is a 63 mm bore compact single-acting pull-type cylinder that operates on one air line. Compressed air retracts the 20 mm rod, while an internal spring extends it back out when pressure drops. This unit delivers a substantial 1225.5 N net pull at 0.5 MPa, reaching 1786.2 N at 0.7 MPa, with the return spring force already subtracted from these figures.
Designed for tight footprints, the short riveted body saves axial mounting depth where larger profile cylinders cannot fit. The 30 mm stroke represents the maximum standard travel for this series. End-of-stroke deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion. This specific SKU lacks a piston magnet, so it cannot accept position switches without upgrading to an -S variant.
Airtac STA Single Acting Compact Guided Cylinder STA63X30 Technical Specifications

| Stroke | 30 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 STA63X30 Is Used
Heavy-Duty Tensioning
Applies up to 1786.2 N of pulling force at 0.7 MPa to draw heavy belting or cabling tight, with the internal spring automatically relaxing tension when air is removed.
Pallet Gate Return
Utilizes the 30 mm stroke to pull a spring-loaded pallet gate closed after a forklift passes, ensuring the barrier normally rests in the safe extended position.
Clamp Release Mechanism
Overcomes a 735 N safe working load to retract a holding pin, allowing the spring force to push the rod out and release manufactured parts from a fixture.
Is the Airtac STA Single Acting Compact Guided Cylinder STA63X30 the Right Cylinder?
When sizing this 63 mm bore model, compare its 1225.5 N net pull at 0.5 MPa against the next size down: the STA50 provides 717.7 N at the same pressure. Since 63 mm is the largest available bore in this single-acting series, exceeding 1786.2 N at 0.7 MPa requires moving to a double-acting SDA configuration. With a 2:1 safety margin, this cylinder can vertically lift approximately 62.5 kg, equating to a safe working load of 735 N.
Verify that the 30 mm stroke ceiling meets your travel requirements, as longer distances require a different cylinder family. Keep in mind the spring-extend behavior: on air loss, the rod drives to its extended rest position and will not hold a mid-stroke load. This model features a PT1/4 port, a female M10x1.5 rod-end thread, and requires a minimum 0.2 MPa operating pressure to overcome the internal 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 STA63X30 FAQ
The STA63X30 provides 1225.5 N of net pull at 0.5 MPa and 1786.2 N at 0.7 MPa. These values already account for the internal return spring resistance, meaning this is the actual usable pulling force generated by the air pressure.
No, it cannot hold a mid-stroke load. As a single-acting pull-type cylinder, the spring drives the rod to its extended position when air is removed. It requires a minimum of 0.2 MPa to overcome the spring and retract the load.
