Airtac STA Single Acting Compact Guided Cylinder STA12X10B
The AirTAC Airtac STA Single Acting Compact Guided Cylinder STA12X10B is a genuine single-acting COMPACT cylinder (single acting, pull type) with a Ø12mm 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 STA12X10B
The AirTAC STA12X10B is a compact single-acting pull-type cylinder, meaning compressed air retracts the 6mm rod while an internal spring extends it back out. It yields 32.4 N of net pull at 0.5 MPa, safely handling a 19 N working load (roughly 60 percent of capacity) or lifting 1.7 kg vertically with a 2:1 margin.
Its short riveted body minimizes axial mounting depth where round-body alternatives fail to fit. This specific B-option unit features a male M5x0.8 piston rod thread, and because it lacks the S magnet code, it cannot accept reed or electronic switches.
Airtac STA Single Acting Compact Guided Cylinder STA12X10B Technical Specifications
| Model | Airtac STA Single Acting Compact Guided Cylinder STA12X10B |
|---|---|
| Series | STA compact single-acting cylinder |
| Bore size | Ø12 mm |
| Stroke | 10 mm |
| Acting type | Single acting, pull type |
| Port size | M5×0.8 |
| Rod end thread | M3×0.5 female / M5×0.8 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 (Ø12mm, Pull)
| Pressure | Pull force (net) |
|---|---|
| 0.5 MPa | 32 N |
| 0.7 MPa | 49 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.
Model Code: Airtac STA Single Acting Compact Guided Cylinder STA12X10B
| STA | Compact single acting, pull type cylinder series. |
|---|---|
| 12 | Bore size in mm. |
| ×10 | Stroke length in mm (single-acting max 30 mm). |
| S | Built-in magnet for magnetic-switch sensing (omit = none). |
| B | Male-thread piston rod (omit = female thread). |
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 STA12X10B Is Used
Clamp Retraction
Uses the 32.4 N net pull to draw a small machining clamp back, letting the internal spring push it forward to grip parts when air stops.
Gate Return
Employs the spring-extend function to keep a lightweight diverter gate open by default, using air pressure to pull the 10mm stroke closed.
Tension Pull-back
Leverages the male M5x0.8 rod end to maintain tension on a packaging film strand, retracting it precisely to clear the packaging path.
Is the Airtac STA Single Acting Compact Guided Cylinder STA12X10B the Right Cylinder?
When sizing this 12mm bore, sizing both ways matters: dropping down is not an option as this is the smallest available STA bore. Stepping up to the STA16 increases the 0.5 MPa net pull to 66.4 N. This 10mm stroke sits well under the 30mm series ceiling.
Remember the spring-extend behavior: on air loss the rod drives outward and will not hold a mid-stroke load. Operating pressure must be 0.2-1.0 MPa to overcome the spring. Verify your bore, stroke, M5x0.8 port, male M5 rod thread, and lack of magnet for this SKU.
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 STA12X10B FAQ
This cylinder provides a net pull of 32.4 N at 0.5 MPa and 49.4 N at 0.7 MPa. It requires an operating pressure of 0.2-1.0 MPa, as at least 0.2 MPa is needed to overcome the internal return spring.
No, this specific SKU lacks a piston magnet so it cannot accept reed or electronic switches. You would need the STA12X10BS variant to utilize the body sensor grooves for position detection.
