Airtac STA Single Acting Compact Guided Cylinder STA32X5N
The AirTAC Airtac STA Single Acting Compact Guided Cylinder STA32X5N is a genuine single-acting COMPACT cylinder (single acting, pull type) with a Ø32mm bore and 5mm 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 STA32X5N
The AirTAC STA32X5N is a compact single-acting pull-type cylinder with a 32 mm bore and 5 mm stroke. Air pressure retracts the 12 mm rod, while an internal spring extends it back out, leaving the unit normally extended at rest. It delivers 290.1 N of net pull at 0.5 MPa, meaning the quoted force already accounts for the spring resistance. A single air line and solenoid port drive the motion, simplifying plumbing.
This thin riveted-body design saves axial mounting depth where standard round-body or profile cylinders will not fit. End-of-stroke deceleration relies on a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion. Operating pressure spans 0.2 to 1.0 MPa, requiring at least 0.2 MPa to overcome the internal spring.
Airtac STA Single Acting Compact Guided Cylinder STA32X5N Technical Specifications
| Model | Airtac STA Single Acting Compact Guided Cylinder STA32X5N |
|---|---|
| Series | STA compact single-acting cylinder |
| Bore size | Ø32 mm |
| Stroke | 5 mm |
| Acting type | Single acting, pull type |
| Port size | PT1/8 |
| Rod end thread | M6×1.0 female / M10×1.25 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 (Ø32mm, Pull)
| Pressure | Pull force (net) |
|---|---|
| 0.5 MPa | 290 N |
| 0.7 MPa | 428 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 STA32X5N
| STA | Compact single acting, pull type cylinder series. |
|---|---|
| 32 | Bore size in mm. |
| ×5 | 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 STA32X5N Is Used
Clamp Retraction
Uses 290.1 N of pull to retract a machining clamp out of the work zone, letting the spring push it safely back into holding position.
Gate Diversion
Pulls a diverter gate inward across a 5 mm travel to alter package flow, relying on the spring to snap the gate open.
Film Tensioning
Draws a tensioning arm back to maintain wrap tightness, venting the line so the spring can release the film roll.
Is the Airtac STA Single Acting Compact Guided Cylinder STA32X5N the Right Cylinder?
When sizing this 32 mm bore, evaluate neighboring options at 0.5 MPa. If 290.1 N is excessive, the STA25 provides 177.7 N; if more pulling power is needed, the STA40 yields 445.1 N. This 5 mm stroke sits well below the 30 mm maximum limit for the series. Keep in mind the spring-extend behavior: on air loss, the rod drives outward and will not hold a mid-stroke load without an external lock.
This specific SKU lacks the -S code, so it has no piston magnet and cannot accept AirTAC reed or electronic switches. It features a female M6x1.0 rod-end thread and a PT1/8 port. The undocumented N suffix carries no defined specification in the standard option set.
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 STA32X5N FAQ
It provides 290.1 N of net pull at 0.5 MPa and 428.3 N at 0.7 MPa. These figures are already net of the return spring resistance.
No, this SKU lacks the -S option, so it has no piston magnet. You would need the -S variant to mount AirTAC reed or electronic switches.
