Airtac SSA Single-Acting Compact Cylinder SSA25X10B
The AirTAC Airtac SSA Single-Acting Compact Cylinder SSA25X10B is a genuine single-acting COMPACT cylinder (single acting, push type) with a Ø25mm bore and 10mm stroke. Air pushes 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 SSA Single-Acting Compact Cylinder SSA25X10B
The AirTAC SSA25X10B is a compact single-acting push-type cylinder where air pressure extends the rod and an internal mechanical spring retracts it. At 0.5 MPa it generates 216.9 N of net push output, meaning the opposing spring force is already subtracted from the raw pneumatic power. This 25 mm bore actuator features a 10 mm stroke and a male M8x1.25 threaded rod end for secure mechanical attachment.
Because it requires only one air line and one solenoid valve port to drive the motion, plumbing is vastly simplified compared to double-acting alternatives. The short riveted body minimizes axial mounting depth, fitting easily into crowded fixtures. End-of-stroke shock is managed by a fixed NBR bumper rather than an adjustable air cushion.
Airtac SSA Single-Acting Compact Cylinder SSA25X10B Technical Specifications
| Model | Airtac SSA Single-Acting Compact Cylinder SSA25X10B |
|---|---|
| Series | SSA compact single-acting cylinder |
| Bore size | Ø25 mm |
| Stroke | 10 mm |
| Acting type | Single acting, push type |
| Port size | M5×0.8 |
| Rod end thread | M5×0.8 female / M8×1.25 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 (Ø25mm, Push)
| Pressure | Push force (net) |
|---|---|
| 0.5 MPa | 217 N |
| 0.7 MPa | 315 N |
These are NET output forces — the return-spring force is already deducted. Single-acting push only; the spring performs the opposite stroke. Size with a safety margin.

Where the Airtac SSA Single-Acting Compact Cylinder SSA25X10B Is Used
Short-Stroke Part Clamping
Uses the 216.9 N net push at 0.5 MPa to secure light metal workpieces against a fixed stop during milling operations.
Package Diverter Ejector
Snaps the 10 mm stroke out rapidly to push small cartons off a sorting line, relying on the internal spring for a swift retraction.
Compact Fixture Locator
Leverages the short riveted body to fit within tight automated assembly jigs where axial space is strictly limited.
Is the Airtac SSA Single-Acting Compact Cylinder SSA25X10B the Right Cylinder?
When sizing this model, compare its 216.9 N net push at 0.5 MPa against adjacent bores. Stepping down, the SSA20 provides 134.1 N, while stepping up to the SSA32 yields 346.6 N at the same pressure. For a practical safe working load, plan for roughly 130 N, which provides a 2:1 safety margin and translates to a vertical lift capacity of about 11.1 kg.
This configuration includes a 10 mm stroke, an M5x0.8 air port, and a male M8x1.25 piston rod. Note the 30 mm maximum standard stroke ceiling. Because the spring drives the return, the cylinder cannot hold a mid-stroke load without live air pressure. This specific SKU lacks a piston magnet, so position sensing is not possible without switching to the -S variant for reed or electronic switches.
Quick checklist
- ✓ Net push 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 SSA Single-Acting Compact Cylinder SSA25X10B FAQ
The net push force is 216.9 N at 0.5 MPa and 315.1 N at 0.7 MPa. These figures already account for the return spring being subtracted from the raw air force.
No, the internal spring drives the rod back to its retracted rest position on air loss, so it cannot hold a mid-stroke load. It also requires a minimum of 0.2 MPa to overcome the spring for extension.
