Airtac SSA Single-Acting Compact Cylinder SSA16X5SB
The AirTAC Airtac SSA Single-Acting Compact Cylinder SSA16X5SB is a genuine single-acting COMPACT cylinder (single acting, push type) with a Ø16mm bore and 5mm 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 SSA16X5SB
The AirTAC SSA16X5SB is a compact single-acting push-type cylinder where air pressure extends the rod and an internal spring retracts it. It provides 80.5 N of net push force at 0.5 MPa, a real design figure already accounting for the return spring. This 16 mm bore unit requires just one air line and one solenoid port, cutting plumbing complexity in tight fixtures.
This specific configuration includes a built-in piston magnet for AirTAC reed or electronic switches, plus a male M5x0.8 threaded rod end for direct mounting. The short riveted body saves axial depth compared to standard round-body cylinders. A fixed NBR bumper decelerates the stroke end, though it is not an adjustable cushion.
Airtac SSA Single-Acting Compact Cylinder SSA16X5SB Technical Specifications
| Model | Airtac SSA Single-Acting Compact Cylinder SSA16X5SB |
|---|---|
| Series | SSA compact single-acting cylinder |
| Bore size | Ø16 mm |
| Stroke | 5 mm |
| Acting type | Single acting, push type |
| Port size | M5×0.8 |
| Rod end thread | M3×0.5 female / M5×0.8 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 (Ø16mm, Push)
| Pressure | Push force (net) |
|---|---|
| 0.5 MPa | 81 N |
| 0.7 MPa | 121 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 SSA16X5SB Is Used
Small Part Ejection
Uses the 5 mm stroke to push light machined components out of a jig with 80.5 N of force at 0.5 MPa.
PCB Edge Clamping
Secures delicate circuit boards during assembly using the male M5x0.8 rod thread to mount a custom soft tip.
Flap Tucking
Tucks carton flaps in confined packaging machinery where the short riveted body conserves axial mounting depth.
Is the Airtac SSA Single-Acting Compact Cylinder SSA16X5SB the Right Cylinder?
When sizing this model, verify the 5 mm stroke and 16 mm bore fit your spatial limits. Stepping down to the SSA12 yields 46.5 N net push at 0.5 MPa, while moving up to the SSA20 provides 134.1 N at the same pressure. This makes the 16 mm bore a middle ground for moderate clamping duties.
Confirm the M5x0.8 port, the -S magnet option, and the -B male M5x0.8 rod thread for your assembly. Operating pressure must be 0.2-1.0 MPa to overcome the spring. Because the spring drives retraction, the SSA16X5SB will not hold a mid-stroke load without live air pressure. A safe working load is roughly 48 N, allowing a vertical lift of about 4.1 kg with a 2:1 margin.
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 SSA16X5SB FAQ
The net push force is 80.5 N at 0.5 MPa and 120.7 N at 0.7 MPa. These figures already subtract the internal return spring force.
Air pressure extends the rod, while the internal spring retracts it when air is released, requiring a minimum of 0.2 MPa to overcome the spring. The included -S magnet works with AirTAC reed or electronic switches for position sensing.
