Airtac SSA Single-Acting Compact Cylinder SSA32X15B
The AirTAC Airtac SSA Single-Acting Compact Cylinder SSA32X15B 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 SSA32X15B
The AirTAC SSA32X15B 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 force at 0.5 MPa, meaning the opposing spring resistance is already subtracted from the raw pneumatic force. Because it requires only one air line and a single solenoid port to drive the motion, plumbing is vastly simplified for short-stroke ejection tasks.
This specific SKU features a 12 mm piston rod with a male M10x1.25 thread, a PT1/8 port, and a 15 mm stroke. The short riveted body saves axial mounting depth where a round-body cylinder will not fit. End-of-stroke impact is managed by a fixed NBR bumper, which decelerates the piston but is not an adjustable air cushion.
Airtac SSA Single-Acting Compact Cylinder SSA32X15B Technical Specifications
| Model | Airtac SSA Single-Acting Compact Cylinder SSA32X15B |
|---|---|
| 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.

Where the Airtac SSA Single-Acting Compact Cylinder SSA32X15B Is Used
Stamping Ejector
Pushes finished metal blanks out of a press die using 346.6 N of net force before the spring retracts the rod clear of the tooling.
Carton Flap Folder
Extends 15 mm to fold minor carton flaps during case packing, relying on the male M10x1.25 thread for a secure clevis attachment.
Lane Diverter Gate
Actuates a short-stroke sorting gate on a conveyor, using the compact riveted body to fit within the narrow conveyor frame profile.
Is the Airtac SSA Single-Acting Compact Cylinder SSA32X15B the Right Cylinder?
When sizing this model, evaluate the neighboring bores using real 0.5 MPa net push figures: stepping down to the SSA25 yields 216.9 N, while stepping up to the SSA40 provides 545.6 N. For the SSA32X15B, a safe working load is roughly 208 N (about 60% of the 346.6 N figure), allowing a vertical lift of approximately 17.7 kg with a 2:1 safety margin. The 15 mm stroke sits well below the 30 mm maximum standard limit.
Remember that on air loss the internal spring drives the rod to its retracted rest position; this unit does not hold a mid-stroke load. To lock a load without live pressure, an external rod lock is required. This configuration includes the male M10x1.25 rod thread (denoted by B) and lacks the S magnet option, meaning it cannot support 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 SSA32X15B FAQ
The SSA32X15B provides a net push force of 346.6 N at 0.5 MPa and 507.5 N at 0.7 MPa. These figures already account for the internal return spring resistance, giving you the true usable output force for your design calculations.
No, if air pressure drops below the 0.2 MPa minimum required to overcome the spring, the internal spring immediately drives the rod back to its fully retracted rest position. It cannot hold a mid-stroke load without live pressure and an external locking device.
