Airtac STA Single Acting Compact Guided Cylinder STA32X5
The AirTAC Airtac STA Single Acting Compact Guided Cylinder STA32X5 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 STA32X5
The AirTAC STA32X5 is a compact single-acting pull-type cylinder where air retracts the rod and an internal spring extends it back out. It provides 290.1 N of net pull at 0.5 MPa, making it highly effective for brief 5 mm tensioning or hold-down tasks. Because the return spring does the extension work, you only need one air line and one solenoid port.
This unit features a short riveted body that saves axial mounting depth where a larger profile cylinder will not fit. It uses a fixed NBR bumper to decelerate the stroke end rather than an adjustable air cushion. Operating pressure ranges from 0.2 to 1.0 MPa, requiring at least 0.2 MPa to overcome the internal spring.
Airtac STA Single Acting Compact Guided Cylinder STA32X5 Technical Specifications
| Model | Airtac STA Single Acting Compact Guided Cylinder STA32X5 |
|---|---|
| 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.

Where the Airtac STA Single Acting Compact Guided Cylinder STA32X5 Is Used
Film Web Tensioning
Uses the 5 mm stroke to pull a tensioning roller back against packaging film, relying on the 290.1 N net pull to maintain consistent material feed.
Clamp Release Mechanism
Air retracts the rod to pull a locking pin out of the way, allowing the internal spring to push the pin back into the extended rest position when air is removed.
Diverter Gate Return
Pulls a sorting gate closed on a conveyor line, with the spring automatically pushing the gate back open to a safe rest state during an air loss.
Is the Airtac STA Single Acting Compact Guided Cylinder STA32X5 the Right Cylinder?
When sizing this model, the 32 mm bore yields 290.1 N net pull at 0.5 MPa. Stepping down, the STA25 provides 177.7 N, while moving up to the STA40 offers 445.1 N at the same pressure. A safe working load is roughly 174 N, which allows a vertical lift of about 14.8 kg with a 2:1 safety margin.
This SKU has no piston magnet and cannot accept a magnetic switch; choose the -S variant if you require reed or electronic sensing. The 5 mm stroke sits well below the 30 mm maximum limit. Remember that on air loss the spring drives the rod to the extended position, so it will not hold a mid-stroke load without an external device. The rod end features a female M6x1.0 thread on a 12 mm rod, with a PT1/8 port.
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 STA32X5 FAQ
The STA32X5 provides a net pull force of 290.1 N at 0.5 MPa and 428.3 N at 0.7 MPa. These figures already account for the force needed to overcome the internal return spring.
No, this specific SKU does not include a piston magnet and cannot accept sensing. You must select the -S option code to add a magnet for AirTAC reed or electronic switches. It also requires a minimum of 0.2 MPa operating pressure to overcome the spring.
