Airtac SSA Single-Acting Compact Cylinder SSA32X20B
The AirTAC Airtac SSA Single-Acting Compact Cylinder SSA32X20B is a genuine single-acting COMPACT cylinder (single acting, push type) with a Ø32mm bore and 20mm 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 SSA32X20B
The AirTAC SSA32X20B 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 provides 346.6 N of net push output, and 507.5 N at 0.7 MPa. Because it requires only one air line and one solenoid port to drive the motion, plumbing is significantly simplified while the short riveted body minimizes axial mounting depth in crowded fixtures.
This specific SKU features a male M10x1.25 piston rod thread on a 12 mm rod. The quoted force is already net of the return spring, giving a real design figure rather than raw air thrust. It uses a fixed NBR bumper to decelerate the stroke end, which is not an adjustable air cushion.
Airtac SSA Single-Acting Compact Cylinder SSA32X20B Technical Specifications
| Model | Airtac SSA Single-Acting Compact Cylinder SSA32X20B |
|---|---|
| Series | SSA compact single-acting cylinder |
| Bore size | Ø32 mm |
| Stroke | 20 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 SSA32X20B Is Used
Stamping Pin Ejection
Uses the 346.6 N net push to eject small stamped metal pins from a die, relying on the internal spring to retract the 12 mm rod when air is cut.
Carton Flap Folding
Applies short 20 mm strokes to fold corrugated carton flaps, where the single air line simplifies valve requirements in tight packaging machinery.
PCB Edge Clamping
Secures circuit boards during routing using the male M10x1.25 threaded rod end, saving axial depth with its compact riveted body.
Is the Airtac SSA Single-Acting Compact Cylinder SSA32X20B the Right Cylinder?
When sizing this 32 mm bore, evaluate your neighbors: the SSA25 provides 216.9 N net push at 0.5 MPa, while the larger SSA40 yields 545.6 N. For the SSA32X20B, a safe working load is roughly 208 N (about 60% of the 0.5 MPa figure), allowing a vertical lift of approximately 17.7 kg with a 2:1 margin. Stroke is capped at 30 mm for this series.
Confirm the 32 mm bore, 20 mm stroke, and PT1/8 port. This variant includes the male M10x1.25 rod thread (-B) and lacks a piston magnet, so it cannot accept reed or electronic switches without the -S option. Remember the spring drives the rod to rest on air loss; it will not hold a mid-stroke load without external devices.
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 SSA32X20B 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 resistance, and the cylinder requires a minimum of 0.2 MPa to overcome the spring.
No, this specific SKU lacks the -S magnet code, so it cannot accept reed or electronic switches. You must select the -S variant to enable position sensing in the body grooves.
