Airtac SSA Single-Acting Compact Cylinder SSA40X5
The AirTAC Airtac SSA Single-Acting Compact Cylinder SSA40X5 is a genuine single-acting COMPACT cylinder (single acting, push type) with a Ø40mm 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 SSA40X5
The AirTAC SSA40X5 is a compact single-acting push-type cylinder where air pressure extends the rod and an internal spring retracts it. It delivers 545.6 N of net push at 0.5 MPa, meaning the return spring force is already subtracted to give you a real design figure. The short riveted body saves axial mounting depth in tight fixtures where longer profile cylinders cannot fit.
This 40 mm bore unit uses a PT1/8 port and a 16 mm piston rod. It relies on a fixed NBR bumper to decelerate the stroke end, which is not an adjustable air cushion. Because this specific SKU lacks the -S magnet option, it cannot accept AirTAC reed or electronic switches for position sensing.
Airtac SSA Single-Acting Compact Cylinder SSA40X5 Technical Specifications
| Model | Airtac SSA Single-Acting Compact Cylinder SSA40X5 |
|---|---|
| Series | SSA compact single-acting cylinder |
| Bore size | Ø40 mm |
| Stroke | 5 mm |
| Acting type | Single acting, push type |
| Port size | PT1/8 |
| Rod end thread | M8×1.25 female / M14×1.5 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 (Ø40mm, Push)
| Pressure | Push force (net) |
|---|---|
| 0.5 MPa | 546 N |
| 0.7 MPa | 797 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.

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 SSA40X5 Is Used
Short-Stroke Part Clamping
Uses the 545.6 N net extension force to secure heavy metal blocks during machining operations within a confined tooling space.
Pallet Ejector
Pushes loaded pallets off a line using a brief 5 mm stroke, relying on the internal spring to retract instantly for the next cycle.
Press Fit Pin Insertion
Applies precise downward pressure to seat small hardware, taking advantage of the compact riveted body to minimize vertical height.
Is the Airtac SSA Single-Acting Compact Cylinder SSA40X5 the Right Cylinder?
When sizing this model, the 545.6 N net push at 0.5 MPa yields a safe working load of roughly 327 N at a 60% margin, or a vertical lift capacity of about 27.8 kg with a 2:1 safety factor. If you need less force, stepping down to the SSA32 provides 346.6 N, while stepping up to the SSA50 offers 874.7 N at the same pressure.
The standard stroke ceiling for this series is 30 mm, so this 5 mm unit fits easily. Remember that with air released, the spring drives the rod back to rest, so it does not hold a mid-stroke load. This configuration confirms a 40 mm bore, 5 mm stroke, PT1/8 port, female M8x1.25 rod thread, and no sensor magnet.
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 SSA40X5 FAQ
The net push force is 545.6 N at 0.5 MPa and 796.9 N at 0.7 MPa. These figures already account for the internal return spring resistance, giving you the true output available for your application.
No. It requires at least 0.2 MPa to overcome the spring and extend. When air is released, the spring drives the rod back to its retracted rest position. It cannot hold a mid-stroke load without live pressure and an external locking device.
