Airtac SSA Single-Acting Compact Cylinder SSA40X15B
The AirTAC Airtac SSA Single-Acting Compact Cylinder SSA40X15B is a genuine single-acting COMPACT cylinder (single acting, push type) with a Ø40mm 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 SSA40X15B
The AirTAC SSA40X15B is a compact single-acting push-type cylinder where air pressure extends the rod and an internal spring retracts it. It provides 545.6 N of net push at 0.5 MPa, meaning the return spring force is already subtracted from the raw air force. This 40 mm bore actuator features a 15 mm stroke and a male M14x1.5 threaded piston rod for direct mounting.
Its short riveted body saves axial mounting depth in tight fixtures where longer profile cylinders cannot fit. A single air line and solenoid port drive the motion, cutting plumbing complexity. The unit relies on a fixed NBR bumper to decelerate at stroke end, operating at speeds of 50-500 mm/s across a temperature range of -20 to +70 C.
Airtac SSA Single-Acting Compact Cylinder SSA40X15B Technical Specifications
| Model | Airtac SSA Single-Acting Compact Cylinder SSA40X15B |
|---|---|
| Series | SSA compact single-acting cylinder |
| Bore size | Ø40 mm |
| Stroke | 15 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.

Where the Airtac SSA Single-Acting Compact Cylinder SSA40X15B Is Used
Stamping Ejector
Uses the 545.6 N net push to eject stamped metal parts from a die, with the internal spring ensuring the rod retracts clear before the next press cycle.
Transfer Gate Diverter
Employs the male M14x1.5 rod to push packages onto a secondary line, fitting into the shallow frame depth alongside the main conveyor belt.
Pallet Stopper Arm
Acts as a compact physical stop for inbound pallets, absorbing end-of-stroke shock via the fixed NBR bumper instead of an adjustable cushion.
Is the Airtac SSA Single-Acting Compact Cylinder SSA40X15B the Right Cylinder?
When sizing this actuator, compare the 545.6 N net push at 0.5 MPa against adjacent bores. Stepping down, the SSA32 yields 346.6 N; stepping up, the SSA50 provides 874.7 N. A practical safe working load is roughly 327 N, offering a 2:1 margin for a vertical lift of about 27.8 kg. This specific SKU includes a male M14x1.5 rod thread and a PT1/8 port, but lacks a piston magnet, so it cannot support magnetic sensing.
Remember the 30 mm maximum standard stroke ceiling for this series. Because it is spring-returned, the SSA40X15B does not hold a mid-stroke load on air loss; the spring drives the rod to its retracted rest position. Operating pressure must be 0.2-1.0 MPa, requiring at least 0.2 MPa to overcome the internal spring.
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 SSA40X15B FAQ
The SSA40X15B provides a net push force of 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 usable output force for your design calculations.
No, it cannot hold a mid-stroke load. As a single-acting push cylinder, an internal spring retracts the rod when air pressure drops below the 0.2 MPa minimum. For load holding without live pressure, you would need a double-acting cylinder with an external rod lock.
