Airtac STA Single Acting Compact Guided Cylinder STA32X25S
The AirTAC Airtac STA Single Acting Compact Guided Cylinder STA32X25S is a genuine single-acting COMPACT cylinder (single acting, pull type) with a Ø32mm bore and 25mm 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 STA32X25S
The AirTAC STA32X25S is a compact single-acting pull-type cylinder where air retracts the rod and an internal spring extends it out. It provides 290.1 N of net pull at 0.5 MPa and 428.3 N at 0.7 MPa. This makes it well suited for tensioning or pulling loads back to a normally extended rest state.
Because the force is already net of the return spring, you can size directly to these ratings. The short riveted body saves axial mounting depth where a longer cylinder will not fit. It includes a built-in piston magnet for position sensing and uses a fixed NBR bumper to decelerate the stroke end rather than an adjustable cushion.
Airtac STA Single Acting Compact Guided Cylinder STA32X25S Technical Specifications
| Model | Airtac STA Single Acting Compact Guided Cylinder STA32X25S |
|---|---|
| Series | STA compact single-acting cylinder |
| Bore size | Ø32 mm |
| Stroke | 25 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 STA32X25S Is Used
Gate Return Mechanism
Uses the spring-extend function to hold a diverter gate open, while the 290.1 N net pull retracts it closed when air is applied.
Film Tensioning
Maintains steady tension on packaging web material by pulling the idler roller back against the product during the cycle.
Vertical Lift Hold-Down
Pulls a 14.8 kg vertical lift fixture securely into its upper rest position using a safe 2:1 load margin at 0.5 MPa.
Is the Airtac STA Single Acting Compact Guided Cylinder STA32X25S the Right Cylinder?
When sizing this 32 mm bore model, compare its 290.1 N net pull at 0.5 MPa against adjacent bores. If you need less force, the STA25 yields 177.7 N; if you need more, the STA40 provides 445.1 N. A practical safe working load is roughly 174 N, which allows a 2:1 margin for a vertical lift of about 14.8 kg.
This configuration has a 25 mm stroke, well under the 30 mm single-acting ceiling. It requires at least 0.2 MPa operating pressure to overcome the spring. The -S code confirms the internal magnet for AirTAC reed or electronic switches, the port is PT1/8, and the rod end is female M6x1.0. Remember the spring drives the rod out on air loss, so it will not hold a mid-stroke load without an external lock.
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 STA32X25S FAQ
This model delivers a net pull of 290.1 N at 0.5 MPa and 428.3 N at 0.7 MPa. The force is already net of the internal spring. It requires an operating pressure of 0.2 to 1.0 MPa, needing at least 0.2 MPa to overcome the spring.
Air pressure retracts the rod, and the internal spring extends it back out when air is released. The included -S magnet allows you to track position with AirTAC reed or electronic switches. A fixed NBR bumper absorbs end-of-stroke shock.
