Airtac SSA Single-Acting Compact Cylinder SSA32X15
The AirTAC Airtac SSA Single-Acting Compact Cylinder SSA32X15 is a genuine single-acting COMPACT cylinder (single acting, push type) with a Ø32mm bore and 15mm 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 SSA32X15
The AirTAC SSA32X15 is a compact single-acting push-type cylinder where air pressure extends the rod and an internal spring retracts it. It generates 346.6 N of net push at 0.5 MPa, meaning the return spring force is already subtracted to give you a real design figure. A safe working load is roughly 208 N, allowing a vertical lift of about 17.7 kg with a 2:1 margin.
This model features a short riveted body that minimizes axial mounting depth in crowded machinery. It uses a fixed NBR bumper to decelerate the stroke end rather than an adjustable air cushion. Because this specific SKU lacks the -S option, it has no piston magnet and cannot accept position switches.
Airtac SSA Single-Acting Compact Cylinder SSA32X15 Technical Specifications
| Model | Airtac SSA Single-Acting Compact Cylinder SSA32X15 |
|---|---|
| Series | SSA compact single-acting cylinder |
| Bore size | Ø32 mm |
| Stroke | 15 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.

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 SSA Single-Acting Compact Cylinder SSA32X15 Is Used
Stamping Ejection
Uses the 346.6 N net push to eject small stamped parts from a die, with the spring safely retracting the rod when air is removed.
Transfer Diversion
Pushes lightweight cartons onto an adjacent conveyor line, relying on the compact body to fit within tight transfer rail clearances.
Pallet Clamping
Secures empty pallets briefly during wrapping, using the 15 mm stroke to apply holding pressure without complex plumbing.
Is the Airtac SSA Single-Acting Compact Cylinder SSA32X15 the Right Cylinder?
When sizing this 32 mm bore unit, consider the SSA25 which provides 216.9 N at 0.5 MPa, or step up to the SSA40 yielding 545.6 N at 0.5 MPa. This SSA32X15 configuration specifies a 15 mm stroke, a PT1/8 port, a 12 mm rod, and a female M6x1.0 rod-end thread. Standard strokes max out at 30 mm.
Operating pressure must sit between 0.2 and 1.0 MPa, as at least 0.2 MPa is required to overcome the internal spring. Remember that upon air loss the spring drives the rod back to rest, so it cannot hold a mid-stroke load without an external locking device.
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 SSA32X15 FAQ
The net push force is 346.6 N at 0.5 MPa and 507.5 N at 0.7 MPa. These values already account for the internal return spring resistance.
No, this specific SKU does not include the -S magnet option, so it cannot accept reed or electronic switches. You would need the -S variant for position sensing.
