Airtac SSA Single-Acting Compact Cylinder SSA20X10
The AirTAC Airtac SSA Single-Acting Compact Cylinder SSA20X10 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 SSA20X10
The AirTAC SSA20X10 is a compact single-acting push-type cylinder where air pressure extends the rod and an internal mechanical spring handles the retraction. Because it requires just one air line and a single solenoid port, plumbing is vastly simplified while saving valuable space in crowded fixtures. This 20 mm bore unit generates 134.1 N of net push force at 0.5 MPa, meaning the opposing spring resistance is already subtracted from the raw pneumatic force.
Designed with a short riveted body, it minimizes axial mounting depth where standard round-body or profile cylinders will not fit. The unit features a fixed NBR bumper at the end of travel to absorb shock rather than an adjustable air cushion. This specific SKU lacks a piston magnet, so it cannot directly accept position switches; adding the -S variant is required for reed or electronic sensor integration.
Airtac SSA Single-Acting Compact Cylinder SSA20X10 Technical Specifications
| Model | Airtac SSA Single-Acting Compact Cylinder SSA20X10 |
|---|---|
| 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 SSA20X10 Is Used
Short-Stroke Part Clamping
Delivers 134.1 N of net extension force at 0.5 MPa to secure light aluminum workpieces against a fixed stop during CNC milling operations.
Package Diverter Ejector
Uses the 10 mm stroke to push small cartons off a main conveyor belt into a packing chute, relying on the internal spring to retract instantly when air is cut.
Bin Shelf Pusher
Advances thin product blister packs forward in a vertical dispensing magazine, saving axial depth inside the machine enclosure with its compact riveted body.
Is the Airtac SSA Single-Acting Compact Cylinder SSA20X10 the Right Cylinder?
When sizing this model, evaluate the neighboring bores to ensure optimal performance. Dropping down to the SSA16 yields 80.5 N of net push at 0.5 MPa, while stepping up to the SSA25 provides 216.9 N at the same pressure. The 20 mm bore offers a computed safe working load of roughly 80 N, which is about 60 percent of its 134.1 N capacity at 0.5 MPa, translating to a vertical lift capability of approximately 6.8 kg with a 2:1 safety margin.
This configuration features a 10 mm stroke, well within the 30 mm maximum standard limit for the series. It uses an M5x0.8 port and a female M4x0.7 rod-end thread on an 8 mm piston rod. Remember that the internal spring actively drives the rod back to its rest position upon air loss; it will not hold a mid-stroke load without live pressure or an external locking device.
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 SSA20X10 FAQ
This single-acting push cylinder provides 134.1 N of net output force 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 thrust for your application.
No, this specific SKU does not include a piston magnet and therefore cannot support reed or electronic switches. You would need to specify the SSA20X10S variant to enable position sensing capabilities.
