Airtac SSA Single-Acting Compact Cylinder SSA16X15B
The AirTAC Airtac SSA Single-Acting Compact Cylinder SSA16X15B is a genuine single-acting COMPACT cylinder (single acting, push type) with a Ø16mm bore and 15mm 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 SSA16X15B
The AirTAC SSA16X15B is a compact single-acting push-type cylinder where air pressure extends the rod and an internal spring handles the retraction. It provides 80.5 N of net push force at 0.5 MPa, meaning the opposing spring resistance is already subtracted from the raw pneumatic power. The short riveted body minimizes axial mounting depth, fitting easily into crowded fixtures where longer profile cylinders cannot.
This specific SKU features a male M5x0.8 threaded piston rod for direct mounting and uses an M5x0.8 air port. Because it lacks the -S option, there is no piston magnet, so magnetic position sensing is not supported on this unit. A fixed NBR bumper absorbs end-of-stroke shock, as there is no adjustable air cushion.
Airtac SSA Single-Acting Compact Cylinder SSA16X15B Technical Specifications
| Model | Airtac SSA Single-Acting Compact Cylinder SSA16X15B |
|---|---|
| Series | SSA compact single-acting cylinder |
| Bore size | Ø16 mm |
| Stroke | 15 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.

| SSA | Compact single acting, push type cylinder series. |
|---|---|
| 16 | Bore size in mm. |
| ×15 | Stroke length in mm (single-acting max 30 mm). |
| S | Built-in magnet for magnetic-switch sensing (omit = none). |

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 SSA16X15B Is Used
Small Part Ejection
Uses the 80.5 N net push at 0.5 MPa to eject small molded components from a tight fixture, with the spring automatically retracting the 6 mm rod.
Package Diverter
Employs the 15 mm stroke to push lightweight cartons on a conveyor line, saving axial space alongside other routing mechanisms.
Light Clamping Jig
Applies a safe working load of roughly 48 N to hold delicate workpieces in place during manual assembly operations.
Is the Airtac SSA Single-Acting Compact Cylinder SSA16X15B the Right Cylinder?
When sizing this 16 mm bore model, 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. The 15 mm stroke sits well below the 30 mm maximum limit for this series. Operating pressure must be at least 0.2 MPa to overcome the internal spring, with a maximum allowable pressure of 1.0 MPa.
This configuration includes the -B male rod thread (M5x0.8) instead of the default female thread. Keep in mind that upon air loss, the spring drives the rod back to its retracted state; 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 SSA16X15B FAQ
The SSA16X15B delivers 80.5 N of net push force at 0.5 MPa and 120.7 N at 0.7 MPa. These figures already account for the internal return spring resistance, giving you the true usable output.
No, this specific SKU does not have the -S option, so it lacks a piston magnet and cannot support reed or electronic sensing. You would need the -S variant to use AirTAC magnetic switches.
