Airtac SSA Single-Acting Compact Cylinder SSA32X15SB
The AirTAC Airtac SSA Single-Acting Compact Cylinder SSA32X15SB 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 SSA32X15SB
The AirTAC SSA32X15SB is a compact single-acting push-type cylinder where air extends the rod and an internal spring retracts it. It delivers 346.6 N of net push at 0.5 MPa, with the return spring force already subtracted from the raw air pressure. This 32 mm bore actuator uses a single air line and one solenoid port, cutting plumbing complexity while fitting into tight fixture layouts.
This specific configuration includes a built-in piston magnet for AirTAC reed or electronic switches, along with a male M10x1.25 threaded rod end for secure mechanical attachments. The short riveted body saves axial mounting depth, and a fixed NBR bumper decelerates the stroke end without requiring adjustment. Operating pressure ranges from 0.2 to 1.0 MPa, requiring at least 0.2 MPa to overcome the internal spring.
Airtac SSA Single-Acting Compact Cylinder SSA32X15SB Technical Specifications
| Model | Airtac SSA Single-Acting Compact Cylinder SSA32X15SB |

| 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 SSA32X15SB Is Used
Short-Stroke Part Clamping
Uses the 346.6 N net push to secure aluminum housings during machining, holding firmly while consuming only one solenoid valve port.
Package Diverting
Extends 15 mm to deflect small cartons on a conveyor line, with the fixed NBR bumper absorbing the repeated end-of-stroke impacts.
Ejector Station
Pushes finished molded parts out of a tight fixture, relying on the internal spring to retract the rod when air pressure is removed.
Is the Airtac SSA Single-Acting Compact Cylinder SSA32X15SB the Right Cylinder?
When sizing this actuator, compare its 346.6 N net push at 0.5 MPa against adjacent bores: the SSA25 provides 216.9 N, while the SSA40 offers 545.6 N. A practical safe working load is roughly 208 N, 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 limit for this series.
Remember that on air loss the spring drives the rod back to its retracted state, so this unit cannot hold a mid-stroke load without external devices. This model is configured with a PT1/8 port, a male M10x1.25 rod thread, and the -S magnet option for position sensing.
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 SSA32X15SB FAQ
The net push force is 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.
Air pressure extends the rod, but when air is released, the internal spring retracts it. The built-in -S magnet allows you to track position with AirTAC reed or electronic switches. A minimum of 0.2 MPa operating pressure is required to overcome the spring.
