Airtac SSA Single-Acting Compact Cylinder SSA50X10B
The AirTAC Airtac SSA Single-Acting Compact Cylinder SSA50X10B 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 SSA50X10B
The AirTAC SSA50X10B is a compact single-acting push-type cylinder where air pressure extends the rod and an internal spring handles the retraction. It provides 874.7 N of net push at 0.5 MPa, meaning the opposing spring force is already subtracted from the raw pneumatic power. This 50 mm bore unit uses a PT1/4 port and features a male M18x1.5 threaded piston rod end for secure mechanical attachments.
Designed with a short riveted body, this actuator minimizes axial mounting depth in crowded machinery where longer profile cylinders cannot fit. It relies on a fixed NBR bumper to decelerate the stroke end rather than an adjustable air cushion. Operating pressure spans 0.2 to 1.0 MPa, requiring at least 0.2 MPa to overcome the internal spring before any extension occurs.
Airtac SSA Single-Acting Compact Cylinder SSA50X10B Technical Specifications
| Model | Airtac SSA Single-Acting Compact Cylinder SSA50X10B |
|---|---|
| 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.

Where the Airtac SSA Single-Acting Compact Cylinder SSA50X10B Is Used
Short-Stroke Pressing
Applies the 874.7 N net push to seat bearings or pins in tight assembly fixtures using the 10 mm stroke.
Vertical Lift Stations
Raises light pallets weighing up to 44.6 kg with a 2:1 safety margin before the spring retracts the rod.
Riveted Body Clamping
Secures heavy workpieces during machining, leveraging the compact riveted body to save axial depth.
Is the Airtac SSA Single-Acting Compact Cylinder SSA50X10B the Right Cylinder?
When sizing this model, compare its 874.7 N net push at 0.5 MPa against adjacent bores: the SSA40 yields 545.6 N, while the SSA63 provides 1382.6 N. A safe working load is approximately 525 N, which is roughly 60 percent of the 0.5 MPa figure, allowing a vertical lift of about 44.6 kg with a 2:1 margin. The 10 mm stroke stays well under the 30 mm series ceiling.
Because it is spring-return, the SSA50X10B will not hold a mid-stroke load if air pressure drops; the spring drives the rod back to its rest position. This specific configuration lacks the -S magnet, so it cannot support reed or electronic switches, and it carries the -B option for the male M18x1.5 rod thread.
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 SSA50X10B FAQ
The net push force is 874.7 N at 0.5 MPa and 1267.4 N at 0.7 MPa. These figures already account for the internal return spring resistance.
No, it is a single-acting push type that needs at least 0.2 MPa to overcome the spring. If air is released, the spring drives the rod back to rest and cannot hold a mid-stroke position.
