Airtac SSA Single-Acting Compact Cylinder SSA20X30BH
The AirTAC SSA Single-Acting Compact Cylinder SSA20X30BH is a genuine single-acting COMPACT cylinder (single acting, push type) with a Ø20mm bore and 30mm 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 SSA20X30BH
The AirTAC SSA20X30BH is a compact single-acting push-type cylinder where air extends the rod and an internal spring retracts it. It generates 134.1 N of net push at 0.5 MPa, making it suitable for short-stroke ejection and clamping. This specific SKU includes a male-thread piston rod and a fluororubber (FKM) seal for enhanced thermal and oil resistance.
Because it is spring-returned, you only need one air line and one solenoid port to drive the motion, which reduces fitting complexity. The short riveted body minimizes axial mounting depth in tight fixtures. A fixed NBR bumper decelerates the stroke end, though it does not lock or hold a mid-stroke load if air pressure is lost.
Airtac SSA Single-Acting Compact Cylinder SSA20X30BH Technical Specifications
| Model | Airtac SSA Single-Acting Compact Cylinder SSA20X30BH |
|---|---|
| Series | SSA compact single-acting cylinder |
| Bore size | Ø20 mm |
| Stroke | 30 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.

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 SSA20X30BH Is Used
Hot-Stamping Ejector
Uses the 134.1 N net push to eject small molded parts, while the FKM seal survives elevated ambient temperatures near heating platens.
Carton Flap Folder
Employs the 30 mm stroke to fold corrugated flaps quickly, relying on the male M6x1.0 rod thread for secure custom tooling attachment.
Pneumatic Edge Clamp
Secures workpieces in confined fixtures where the short riveted body saves axial space, returning automatically via spring when air is cut.
Is the Airtac SSA Single-Acting Compact Cylinder SSA20X30BH the Right Cylinder?
When sizing this model, consider the neighboring bores: stepping down to the SSA16 yields 80.5 N at 0.5 MPa, while stepping up to the SSA25 provides 216.9 N. The 30 mm stroke represents the maximum standard limit for this series.
This configuration confirms a 20 mm bore, 30 mm stroke, M5x0.8 port, and a male M6x1.0 rod thread. It requires an operating pressure of 0.2-1.0 MPa to overcome the return spring. Note that this unit lacks the -S magnet, so it cannot accept position switches, and it will not hold a load without live air pressure.
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 SSA20X30BH FAQ
The net push force is 134.1 N at 0.5 MPa and 196.9 N at 0.7 MPa. These figures already account for the return spring resistance, giving you the true usable output for your design calculations.
No, this specific SKU does not include the -S piston magnet, so it cannot accept reed or electronic switches. You must select the -S variant if position sensing is required for your application.
