Airtac SSA Single-Acting Compact Cylinder SSA20X15B
The AirTAC Airtac SSA Single-Acting Compact Cylinder SSA20X15B is a genuine single-acting COMPACT cylinder (single acting, push type) with a Ø20mm 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 SSA20X15B
The AirTAC SSA20X15B is a compact single-acting push-type cylinder where air extends the rod and an internal spring retracts it. It provides 134.1 N of net push at 0.5 MPa, meaning the quoted force already accounts for the return spring resistance. This 20 mm bore, 15 mm stroke model is normally retracted at rest.
Featuring a short riveted body, it saves axial mounting depth where a round-body cylinder will not fit. This specific SKU includes a male M6x1.0 piston rod thread and lacks a piston magnet, so it cannot accept magnetic switches. A fixed NBR bumper decelerates the stroke end, though it is not an adjustable air cushion.
Airtac SSA Single-Acting Compact Cylinder SSA20X15B Technical Specifications
| Model | Airtac SSA Single-Acting Compact Cylinder SSA20X15B |
|---|---|
| Series | SSA compact single-acting cylinder |
| Bore size | Ø20 mm |
| Stroke | 15 mm |
| Acting type | Single acting, push type |
| Port size | M5×0.8 |
| Rod end thread | M4×0.7 female / M6×1.0 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 (Ø20mm, Push)
| Pressure | Push force (net) |
|---|---|
| 0.5 MPa | 134 N |
| 0.7 MPa | 197 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.

| SSA | Compact single acting, push type cylinder series. |
|---|---|
| 20 | Bore size in mm. |
| ×15 | Stroke length in mm (single-acting max 30 mm). |
| S | Built-in magnet for magnetic-switch sensing (omit = none). |
| B | Male-thread piston rod (omit = female thread). |
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 SSA20X15B Is Used
Small Part Stamping
Applies 134.1 N of net push at 0.5 MPa to seat thin sheet metal blanks into dies.
Package Diverter
Uses the 15 mm stroke to push lightweight cartons off a narrow belt line.
PCB Edge Clamping
Secures delicate circuit boards during routing without overwhelming the fixture.
Is the Airtac SSA Single-Acting Compact Cylinder SSA20X15B the Right Cylinder?
When sizing this model, consider the neighboring bores: the 16 mm version yields 80.5 N net push at 0.5 MPa, while the 25 mm version provides 216.9 N. A safe working load for this 20 mm bore is approximately 80 N, offering a 2:1 margin for a vertical lift of about 6.8 kg. Operating pressure must be 0.2-1.0 MPa, as at least 0.2 MPa is required to overcome the spring.
Confirm the 20 mm bore, 15 mm stroke, and M5x0.8 air port suit your manifold. This configuration uses a male M6x1.0 rod thread and has no magnet. Because the spring drives the rod to its retracted rest position on air loss, it cannot hold a mid-stroke load; use a double-acting SDA with an external rod lock if positioning is required.
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 SSA20X15B FAQ
The net push force is 134.1 N at 0.5 MPa and 196.9 N at 0.7 MPa. These figures already subtract the internal return spring resistance.
No, this specific SKU lacks the -S option and has no piston magnet, so it cannot take reed or electronic switches. You must select the -S variant for sensing.
