Airtac SSA Single-Acting Compact Cylinder SSA16X15SB
The AirTAC Airtac SSA Single-Acting Compact Cylinder SSA16X15SB 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 SSA16X15SB
The AirTAC SSA16X15SB is a compact single-acting push-type cylinder where air extends the rod and an internal spring retracts it. It generates 80.5 N of net push at 0.5 MPa, meaning the return spring force is already subtracted from the raw air pressure. This 16 mm bore unit features a built-in magnet for position sensing and a male M5x0.8 threaded piston rod.
Its short riveted body minimizes axial mounting depth in crowded fixtures. Because it only requires one air line and one solenoid port to drive the motion, plumbing is simplified and valve costs drop. A fixed NBR bumper handles end-of-stroke deceleration, though it is not an adjustable air cushion.
Airtac SSA Single-Acting Compact Cylinder SSA16X15SB Technical Specifications
| Model | Airtac SSA Single-Acting Compact Cylinder SSA16X15SB |
|---|---|
| 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.

Where the Airtac SSA Single-Acting Compact Cylinder SSA16X15SB Is Used
Small Part Ejection
Uses the 80.5 N net push to eject small stamped components from a tight die cavity before the press cycles.
Fixture Clamping
Applies reliable clamping force to delicate workpieces in confined machining cells where axial depth is restricted.
Carton Flap Folding
Extends 15 mm to tuck packaging flaps on an automated line, relying on the internal spring to retract instantly between cycles.
Is the Airtac SSA Single-Acting Compact Cylinder SSA16X15SB the Right Cylinder?
When sizing this model, compare its 80.5 N net push at 0.5 MPa against adjacent bores. Stepping down to the SSA12 yields 46.5 N, while stepping up to the SSA20 provides 134.1 N. This 16 mm bore offers 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.
This configuration has a 15 mm stroke, well under the 30 mm maximum ceiling. It requires a minimum operating pressure of 0.2 MPa to overcome the internal spring. The rod end is male M5x0.8, the air port is M5x0.8, and the -S magnet enables detection via reed or electronic switches. Note that without live air pressure, the spring returns the rod to rest and cannot hold a mid-stroke load.
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 SSA16X15SB 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, giving you the true usable output.
Air pressure extends the rod, while an internal spring retracts it when air is released. It requires a minimum of 0.2 MPa to overcome the spring, and the included -S magnet works with reed or electronic switches for position confirmation.
