Airtac SSA Single-Acting Compact Cylinder SSA16X5
The AirTAC Airtac SSA Single-Acting Compact Cylinder SSA16X5 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 SSA16X5
The AirTAC SSA16X5 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 at 0.5 MPa, meaning the return spring force is already subtracted to give you a reliable design figure. This short 5 mm stroke excels in tight fixtures where axial depth is restricted.
Because it requires only one air line and one solenoid port, plumbing is vastly simplified. The riveted body design minimizes footprint, and a fixed NBR bumper absorbs end-of-stroke shock without needing adjustment.
Airtac SSA Single-Acting Compact Cylinder SSA16X5 Technical Specifications
| Model | Airtac SSA Single-Acting Compact Cylinder SSA16X5 |
|---|---|
| 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.
Model Code: Airtac SSA Single-Acting Compact Cylinder SSA16X5
| SSA | Compact single acting, push type cylinder series. |
|---|---|
| 16 | Bore size in mm. |
| ×5 | Stroke length in mm (single-acting max 30 mm). |
| S | Built-in magnet for magnetic-switch sensing (omit = none). |
| B | Male-thread piston rod (omit = female thread). |
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 SSA16X5 Is Used
Small Part Ejection
Uses the 80.5 N net push to eject small molded components from a tight fixture without requiring a return air line.
Light Clamping
Applies 5 mm of stroke to hold light materials in place, relying on the internal spring to release the clamp safely.
Compact Diverting
Fits into shallow machinery profiles to push lightweight items across a conveyor junction using a single solenoid port.
Is the Airtac SSA Single-Acting Compact Cylinder SSA16X5 the Right Cylinder?
When sizing this 16 mm bore unit, consider the neighboring options. Stepping down to the SSA12 yields 46.5 N at 0.5 MPa, while moving up to the SSA20 provides 134.1 N at 0.5 MPa. This SSA16X5 strikes a balance with a safe working load of roughly 48 N, which translates to a vertical lift capacity of about 4.1 kg with a 2:1 safety margin.
Remember that standard strokes max out at 30 mm. This specific SKU lacks the -S magnet, so it cannot accept position switches. It features a female M3x0.5 rod-end thread, a 6 mm rod, and an M5x0.8 port. Since the spring drives retraction, the cylinder will not hold a mid-stroke load if air pressure drops.
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 SSA16X5 FAQ
The net push force is 80.5 N at 0.5 MPa and 120.7 N at 0.7 MPa. These figures already account for the internal return spring resistance.
No, this specific SKU does not include the -S magnet code. You must select the -S variant to use AirTAC reed or electronic switches for position sensing.
