Airtac SSA Single-Acting Compact Cylinder SSA50X10S
The AirTAC Airtac SSA Single-Acting Compact Cylinder SSA50X10S is a genuine single-acting COMPACT cylinder (single acting, push type) with a Ø50mm bore and 10mm 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 SSA50X10S
The AirTAC SSA50X10S is a compact single-acting push-type cylinder where air pressure extends the rod and an internal spring retracts it. It delivers a true net push of 874.7 N at 0.5 MPa, providing substantial force for a 10 mm stroke. This figure already subtracts the return-spring resistance, giving you a reliable design parameter rather than raw air pressure.
Its short riveted body saves valuable axial mounting depth in crowded machinery. The integrated -S piston magnet enables position detection using an AirTAC reed or electronic switch, while the fixed NBR bumper absorbs end-of-stroke shock without requiring adjustment.
Airtac SSA Single-Acting Compact Cylinder SSA50X10S Technical Specifications
| Model | Airtac SSA Single-Acting Compact Cylinder SSA50X10S |
|---|---|
| Series | SSA compact single-acting cylinder |
| Bore size | Ø50 mm |
| Stroke | 10 mm |
| Acting type | Single acting, push type |
| Port size | PT1/4 |
| Rod end thread | M10×1.5 female / M18×1.5 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 (Ø50mm, Push)
| Pressure | Push force (net) |
|---|---|
| 0.5 MPa | 875 N |
| 0.7 MPa | 1267 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 SSA50X10S Is Used
Heavy-Duty Stamping Ejector
Uses the 874.7 N net extension force to positively eject dense metal stampings from a die cavity within a tight 10 mm window.
Pallet Stop Gate
Acts as a robust spring-return stop pin in conveyor lines, extending to halt heavy pallets and retracting safely when air pressure drops.
Fixture Clamping Arm
Generates secure holding force against workpieces in machining fixtures, relying on the compact riveted body to fit within restricted tooling envelopes.
Is the Airtac SSA Single-Acting Compact Cylinder SSA50X10S the Right Cylinder?
When sizing this 50 mm bore model, compare its 874.7 N net push at 0.5 MPa against adjacent bores. Stepping down, the SSA40 yields 545.6 N; stepping up, the SSA63 provides 1382.6 N. A practical safe working load is roughly 525 N, which allows a 2:1 margin for a vertical lift of about 44.6 kg.
This configuration features a 20 mm rod, a PT1/4 port, and a female M10x1.5 rod-end thread. Remember the 30 mm maximum stroke ceiling. Because the spring drives retraction, the SSA50X10S cannot hold a mid-stroke load without live air pressure. Operating pressure must be 0.2-1.0 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 SSA50X10S FAQ
The cylinder provides a net push of 874.7 N at 0.5 MPa and 1267.4 N at 0.7 MPa. These values already account for the internal return-spring resistance.
No. Air extends the rod and the internal spring retracts it. Upon air loss, the spring drives the rod back to its rest position. It requires at least 0.2 MPa operating pressure to overcome the spring and function properly.
