Airtac SSA Single-Acting Compact Cylinder SSA50X5S
The AirTAC Airtac SSA Single-Acting Compact Cylinder SSA50X5S is a genuine single-acting COMPACT cylinder (single acting, push type) with a Ø50mm 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 SSA50X5S
The AirTAC SSA50X5S is a compact single-acting push-type cylinder where air pressure extends the rod and an internal mechanical spring retracts it. Operating at 0.5 MPa, this 50 mm bore unit generates 874.7 N of net push force, which already accounts for the return spring resistance. The riveted body design drastically reduces axial mounting depth, fitting easily into crowded machinery where longer profile alternatives cannot.
This specific configuration includes the S option, meaning a built-in piston magnet enables position detection using an AirTAC reed or electronic switch. End-of-stroke energy is managed solely by a fixed NBR bumper, which decelerates the motion but is not an adjustable air cushion. With a 5 mm stroke, it is purpose-built for high-force, short-travel operations.
Airtac SSA Single-Acting Compact Cylinder SSA50X5S Technical Specifications
| Model | Airtac SSA Single-Acting Compact Cylinder SSA50X5S |
|---|---|
| Series | SSA compact single-acting cylinder |
| Bore size | Ø50 mm |
| Stroke | 5 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.

Where the Airtac SSA Single-Acting Compact Cylinder SSA50X5S Is Used
Heavy-Duty Staking
Delivers 874.7 N of net force at 0.5 MPa to drive solid rivets or stake metal components securely in a 5 mm travel envelope.
Short-Travel Holding
Applies over 1267 N of clamping thrust at 0.7 MPa to lock heavy workpieces against a fixture stop before machining begins.
Part Ejection
Uses the internal spring to retract the 20 mm rod rapidly, pushing finished parts out of a press area before the next cycle.
Is the Airtac SSA Single-Acting Compact Cylinder SSA50X5S the Right Cylinder?
When sizing this model, evaluate your force requirements against the neighboring bores. Stepping down to the SSA40 yields 545.6 N of net push at 0.5 MPa, while stepping up to the SSA63 provides 1382.6 N at the same pressure. For the SSA50X5S, a safe working load is approximately 525 N, representing about 60% of the 874.7 N available at 0.5 MPa, which translates to a vertical lift capacity of roughly 44.6 kg with a 2:1 safety margin.
Remember that the 30 mm standard stroke ceiling applies to this series, and this 5 mm variant is well within limits. Because it is spring-returned, the SSA50X5S cannot hold a mid-stroke load without live air pressure; the spring drives the rod back to rest upon air loss. This model features a PT1/4 port, a 20 mm rod, female M10x1.5 rod-end threads, and the -S magnet for switch sensing.
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 SSA50X5S FAQ
The net push force is 874.7 N at 0.5 MPa and 1267.4 N at 0.7 MPa. These figures already subtract the return spring resistance, giving you the actual usable output for your design calculations.
Air pressure extends the rod, but when air is released, the internal spring retracts it, requiring a minimum of 0.2 MPa to overcome the spring. The included -S magnet allows you to track piston position using an AirTAC reed or electronic switch.
