Airtac SSA Single-Acting Compact Cylinder SSA20X30B
The AirTAC Airtac SSA Single-Acting Compact Cylinder SSA20X30B 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 SSA20X30B
The AirTAC SSA20X30B is a compact single-acting push-type cylinder where air pressure extends the rod and an internal mechanical spring retracts it. It provides a real net push output of 134.1 N at 0.5 MPa, meaning the opposing spring force is already subtracted for accurate sizing. The short riveted body design minimizes axial mounting depth, fitting easily into crowded fixtures where longer profile cylinders cannot.
This specific SKU features a male M6x1.0 threaded piston rod end for direct mounting, operating on a single M5x0.8 air port. Because it only requires one airline and one solenoid valve port, plumbing is drastically simplified. A fixed NBR bumper handles end-of-stroke deceleration, and the unit runs at speeds between 50-500 mm/s.
Airtac SSA Single-Acting Compact Cylinder SSA20X30B Technical Specifications
| Model | Airtac SSA Single-Acting Compact Cylinder SSA20X30B |
|---|---|
| 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.

Where the Airtac SSA Single-Acting Compact Cylinder SSA20X30B Is Used
Short-Stroke Part Ejection
Uses the 134.1 N net push to positively eject machined components from a fixture, saving axial space with its compact riveted body.
Product Diverting Gate
Extends 30 mm to actuate a lightweight diverter arm on a packaging line, relying on the internal spring to retract when air is released.
Male-Thread Tool Clamping
Leverages the male M6x1.0 rod end to thread directly into a custom clamp block, securing parts during light assembly operations.
Is the Airtac SSA Single-Acting Compact Cylinder SSA20X30B the Right Cylinder?
When sizing this 20 mm bore unit, evaluate your neighbors: the smaller SSA16 yields 80.5 N net push at 0.5 MPa, while the larger SSA25 provides 216.9 N. For the SSA20X30B, a safe working load is approximately 80 N (about 60% of the 134.1 N figure), allowing a vertical lift of roughly 6.8 kg with a 2:1 margin. Note the 30 mm stroke is the maximum standard length for this series.
Confirm the bore and stroke match your space constraints, along with the M5x0.8 port and male M6x1.0 rod thread. Operating pressure must be 0.2-1.0 MPa, as at least 0.2 MPa is required to overcome the return spring. This SKU lacks the -S magnet code, so position sensing is not possible without upgrading to the -S variant for 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 SSA20X30B FAQ
The SSA20X30B provides a net push force of 134.1 N at 0.5 MPa and 196.9 N at 0.7 MPa. These figures already account for the internal return spring resistance, giving you the true usable output for your design calculations.
No, the internal spring drives the rod back to its retracted rest position upon air loss, so it cannot hold a mid-stroke load. It requires a minimum of 0.2 MPa operating pressure to overcome the spring and extend the rod.
