Airtac SSA Single-Acting Compact Cylinder SSA20X10N
The AirTAC SSA Single-Acting Compact Cylinder SSA20X10N is a genuine single-acting COMPACT cylinder (single acting, push type) with a Ø20mm bore and 10mm 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 SSA20X10N
The AirTAC SSA20X10N is a compact single-acting push-type cylinder where compressed air extends the rod and an internal mechanical spring handles the retraction. It yields 134.1 N of net push at 0.5 MPa, a figure that already accounts for the spring's opposing resistance. Because only one air line and one solenoid port are required to drive the motion, plumbing complexity drops alongside valve costs.
This model features a short riveted body that minimizes axial mounting depth, fitting easily into crowded machinery where longer profile alternatives fail. The bore dictates an 8 mm piston rod and an M5x0.8 port. End-of-stroke energy is managed by a fixed NBR bumper, which decelerates the piston without acting as a mid-stroke lock.
Airtac SSA Single-Acting Compact Cylinder SSA20X10N Technical Specifications
| Model | Airtac SSA Single-Acting Compact Cylinder SSA20X10N |
|---|---|
| Series | SSA compact single-acting cylinder |
| Bore size | Ø20 mm |
| Stroke | 10 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 SSA20X10N Is Used
PCB Edge Clamping
Applies 134.1 N of net push at 0.5 MPa to secure delicate circuit boards during routing, using the short 10 mm stroke to save fixture depth.
Small Parts Diverter
Ejects lightweight plastic components off a belt line, relying on the spring-return mechanism to retract the 8 mm rod when the single solenoid de-energizes.
Carton Flap Tucking
Tucks minor flaps on small packaging boxes using a compact riveted body that fits neatly within tight conveyor side-guides.
Is the Airtac SSA Single-Acting Compact Cylinder SSA20X10N the Right Cylinder?
When sizing this 20 mm bore actuator, compare its 134.1 N net push at 0.5 MPa against adjacent options: dropping down to the SSA16 provides 80.5 N, while stepping up to the SSA25 yields 216.9 N. This SSA20X10N configuration carries a 10 mm stroke, well under the 30 mm series ceiling, and operates across a 50-500 mm/s speed range. Because it lacks the -S suffix, this specific SKU has no piston magnet and cannot host reed or electronic switches.
Remember that air pressure must stay between 0.2 and 1.0 MPa, as a minimum of 0.2 MPa is necessary to overcome the internal spring. Upon air loss, the spring actively drives the rod back to its retracted state, meaning it cannot hold a mid-stroke load without external mechanical locking. The rod-end thread is female M4x0.7 unless specified otherwise.
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 SSA20X10N FAQ
This single-acting push cylinder provides 134.1 N of net force at 0.5 MPa and 196.9 N at 0.7 MPa. These values already subtract the return spring resistance, giving you a true design figure for your pushing application.
No, this specific SKU does not include a piston magnet. You must select the -S option variant to mount AirTAC reed or electronic switches in the body grooves for position detection.
