Airtac STA Single Acting Compact Guided Cylinder STA40X10
The AirTAC Airtac STA Single Acting Compact Guided Cylinder STA40X10 is a genuine single-acting COMPACT cylinder (single acting, pull type) with a Ø40mm 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 STA40X10
The AirTAC STA40X10 is a compact single-acting pull-type cylinder. Air pressure retracts the 16 mm rod, while an internal spring extends it out when air is released. It provides 445.1 N of net pull at 0.5 MPa, safely handling a working load of roughly 267 N or vertically lifting about 22.7 kg with a 2:1 margin.
This thin riveted body saves axial mounting depth where larger profile cylinders will not fit. A fixed NBR bumper decelerates the stroke end, but it is not an adjustable air cushion. This base SKU lacks a piston magnet, so it cannot accept position switches.
Airtac STA Single Acting Compact Guided Cylinder STA40X10 Technical Specifications
| Model | Airtac STA Single Acting Compact Guided Cylinder STA40X10 |
|---|---|
| Series | STA compact single-acting cylinder |
| Bore size | Ø40 mm |
| Stroke | 10 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.

| STA | Compact single acting, pull type cylinder series. |
|---|---|
| 40 | Bore size in mm. |
| ×10 | Stroke length in mm (single-acting max 30 mm). |
| S | Built-in magnet for magnetic-switch sensing (omit = none). |

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 STA40X10 Is Used
Tensioning Mechanisms
Uses the 445.1 N net pull to draw tension cables or belts tight, with the spring automatically slacking the line when air is removed.
Gate Diversion
Pulls a diverter gate out of the product flow path on demand, letting the internal spring snap it back to the blocking position for fail-safe routing.
Hold-Down Release
Retracts a 16 mm rod to release a clamped carton for ejection, where the compact riveted body minimizes frame interference.
Is the Airtac STA Single Acting Compact Guided Cylinder STA40X10 the Right Cylinder?
Size this unit against its neighbors: the STA32 yields 290.1 N net pull at 0.5 MPa, while the STA50 provides 717.7 N. This 40 mm bore hits 445.1 N at 0.5 MPa (656.2 N at 0.7 MPa). The 10 mm stroke sits well below the 30 mm family ceiling.
Because the spring constantly pushes outward, the rod moves to the extended rest position on air loss and will not hold a mid-stroke load. Use a double-acting SDA with an external rod lock if you need to freeze a load. This configuration specifies 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 STA40X10 FAQ
The net pull force is 445.1 N at 0.5 MPa and 656.2 N at 0.7 MPa. Operating pressure ranges from 0.2 to 1.0 MPa, requiring at least 0.2 MPa to overcome the return spring.
No, this specific SKU does not include a piston magnet. You must select the STA40X10S variant to use AirTAC reed or electronic switches in the body sensor grooves.
