Airtac SSA Single-Acting Compact Cylinder SSA32X25SB
The AirTAC Airtac SSA Single-Acting Compact Cylinder SSA32X25SB is a genuine single-acting COMPACT cylinder (single acting, push type) with a Ø32mm bore and 25mm 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 SSA32X25SB
The AirTAC SSA32X25SB is a compact single-acting push-type cylinder where air extends the rod and an internal spring retracts it. It provides 346.6 N of net push force at 0.5 MPa and 507.5 N at 0.7 MPa, with the return spring counterforce already subtracted for accurate sizing. A short riveted body saves axial mounting depth in crowded fixtures where longer profile cylinders will not fit.
This specific configuration includes a built-in piston magnet for position sensing alongside a male M10x1.25 threaded rod end. A fixed NBR bumper decelerates the stroke end, meaning it is not an adjustable air cushion. Operating pressure runs from 0.2 to 1.0 MPa, requiring at least 0.2 MPa to overcome the internal spring.
Airtac SSA Single-Acting Compact Cylinder SSA32X25SB Technical Specifications
| Model | Airtac SSA Single-Acting Compact Cylinder SSA32X25SB |
|---|---|
| Series | SSA compact single-acting cylinder |
| Bore size | Ø32 mm |
| Stroke | 25 mm |
| Acting type | Single acting, push 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, Push)
| Pressure | Push force (net) |
|---|---|
| 0.5 MPa | 347 N |
| 0.7 MPa | 508 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 SSA32X25SB Is Used
Die Clamping
Secures stamping dies in tight press beds using 346.6 N of net push force, saving axial space with its compact riveted body.
Package Diverting
Extends 25 mm to push lightweight cartons off a sorting line, relying on the internal spring to retract when air is released.
Part Ejection
Ejects machined components from a fixture using the male M10x1.25 threaded rod, handling a safe working load of 208 N.
Is the Airtac SSA Single-Acting Compact Cylinder SSA32X25SB the Right Cylinder?
Sizing this 32 mm bore involves comparing it to neighboring options. Stepping down to the SSA25 yields 216.9 N net push at 0.5 MPa, while moving up to the SSA40 provides 545.6 N. The 346.6 N rating of this model supports a safe working load around 208 N (roughly 60 percent of capacity) or a vertical lift of 17.7 kg with a 2:1 safety margin. The 25 mm stroke sits safely under the 30 mm maximum ceiling.
Because it is spring-return, the SSA32X25SB cannot hold a mid-stroke load without live air pressure. The PT1/8 port drives the extension, and this SKU reflects the -S magnet for reed or electronic switches plus the -B male M10x1.25 rod thread.
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 SSA32X25SB FAQ
The net push force is 346.6 N at 0.5 MPa and 507.5 N at 0.7 MPa. These figures already subtract the return spring counterforce, giving you a real design value for sizing.
No, the internal spring drives the rod back to its retracted rest position on air loss. It cannot hold a mid-stroke load, and operating pressure must be at least 0.2 MPa to overcome the spring.
