Airtac SSA Single-Acting Compact Cylinder SSA16X15S
The AirTAC Airtac SSA Single-Acting Compact Cylinder SSA16X15S 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 SSA16X15S
The AirTAC SSA16X15S is a compact single-acting push-type cylinder where air pressure extends the rod and an internal mechanical spring handles the retraction. It provides 80.5 N of net push at 0.5 MPa and 120.7 N at 0.7 MPa, with the return spring force already subtracted from these figures. Because it relies on a spring for the return motion, it cannot be loaded on the return stroke.
Featuring a built-in piston magnet (-S), this unit supports AirTAC reed or electronic switches for position sensing. The short riveted body minimizes axial mounting depth in tight machinery, while a fixed NBR bumper decelerates the stroke end. It requires only one air line and one solenoid port, simplifying plumbing and reducing valve costs.
Airtac SSA Single-Acting Compact Cylinder SSA16X15S Technical Specifications
| Model | Airtac SSA Single-Acting Compact Cylinder SSA16X15S |
|---|---|
| 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 SSA16X15S Is Used
Small Part Ejection
Uses the 80.5 N net push to eject small molded components from a die, with the spring safely retracting the rod when air is cut.
Package Diverting
Fits into narrow conveyor frames to push light cartons onto a branching line, needing only a single M5x0.8 air line.
Thin Material Clamping
Applies short-stroke clamping force to hold sheet metal, relying on the compact riveted body to fit within tight fixture depths.
Is the Airtac SSA Single-Acting Compact Cylinder SSA16X15S the Right Cylinder?
When sizing this 16 mm bore unit, consider the neighboring bores: 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 SSA16X15S configuration features a 15 mm stroke, well within the 30 mm maximum standard limit, and uses an M5x0.8 port. The piston rod is 6 mm with a female M3x0.5 rod-end thread.
Operating pressure must be 0.2-1.0 MPa, as at least 0.2 MPa is required to overcome the internal return spring. A safe working load is roughly 48 N, equating to a vertical lift of about 4.1 kg with a 2:1 margin. Remember that on air loss the spring drives the rod back to rest; it does not hold a mid-stroke load. The -S magnet enables switch integration, and the fixed NBR bumper is not an adjustable air cushion.
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 SSA16X15S FAQ
The net push force is 80.5 N at 0.5 MPa and 120.7 N at 0.7 MPa. These values already account for the internal return spring resistance.
No, it is a single-acting push cylinder. When air is released, the internal spring drives the rod back to its retracted rest position. It requires a minimum of 0.2 MPa to overcome the spring and does not hold a mid-stroke load.
