Airtac STA Single Acting Compact Guided Cylinder STA40X15N
The AirTAC Airtac STA Single Acting Compact Guided Cylinder STA40X15N is a genuine single-acting COMPACT cylinder (single acting, pull type) with a Ø40mm bore and 15mm 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 STA40X15N
The AirTAC STA40X15N is a compact single-acting pull-type cylinder where compressed air retracts the 16 mm rod and an internal spring pushes it back out. It yields 445.1 N of net pull at 0.5 MPa, safely handling a working load of roughly 267 N or lifting 22.7 kg vertically with a 2:1 margin. This unit lacks a piston magnet and cannot accept position switches.
Its short riveted body saves valuable axial mounting depth where larger profile or round-body units fail to fit. End-of-stroke deceleration relies strictly on a fixed NBR bumper, which is not an adjustable air cushion or a locking mechanism.
Airtac STA Single Acting Compact Guided Cylinder STA40X15N Technical Specifications
| Model | Airtac STA Single Acting Compact Guided Cylinder STA40X15N |
|---|---|
| Series | STA compact single-acting cylinder |
| Bore size | Ø40 mm |
| Stroke | 15 mm |
| Acting type | Single acting, pull type |
| Port size | PT1/8 |
| Rod end thread | M8×1.25 female / M14×1.5 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 (Ø40mm, Pull)
| Pressure | Pull force (net) |
|---|---|
| 0.5 MPa | 445 N |
| 0.7 MPa | 656 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 STA40X15N Is Used
Tension Gate Closure
Uses the spring-extend function to hold a conveyor diverter gate open, with the 445.1 N air pull retracting the rod to close the gate on demand.
Carton Flap Hold-Down
Pulls a mechanical arm down to secure packaging flaps during a 15 mm gluing cycle, releasing tension instantly when air is vented.
Vertical Lift Return
Lifts a 22.7 kg fixture vertically using a 2:1 safety margin on the 0.5 MPa pull stroke, letting the spring drive the payload back down.
Is the Airtac STA Single Acting Compact Guided Cylinder STA40X15N the Right Cylinder?
When sizing this 40 mm bore, stepping down to the STA32 yields 290.1 N of net pull at 0.5 MPa, while stepping up to the STA50 provides 717.7 N. This model requires at least 0.2 MPa of operating pressure to overcome the internal spring, with a maximum limit of 1.0 MPa.
The 15 mm stroke sits well below the 30 mm series ceiling. Because air loss forces the rod to its extended rest position, this cylinder cannot hold a mid-stroke load without external devices. This specific SKU features a PT1/8 port, a female M8x1.25 rod-end thread, and no magnet.
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 STA40X15N FAQ
This cylinder provides 445.1 N of net pull at 0.5 MPa and 656.2 N at 0.7 MPa. It requires an operating pressure between 0.2 and 1.0 MPa, needing at least 0.2 MPa to overcome the return spring.
No, this specific SKU does not include a piston magnet and cannot accept reed or electronic switches. You would need the -S variant to enable sensor functionality in the body grooves.
