Airtac SSA Single-Acting Compact Cylinder SSA50X5B
The AirTAC SSA Single-Acting Compact Cylinder SSA50X5B 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 SSA50X5B
The AirTAC SSA50X5B is a compact single-acting push-type cylinder where air extends the rod and an internal spring retracts it. It provides 874.7 N net push at 0.5 MPa, meaning the return spring force is already subtracted to give a real design figure. This short 5 mm stroke unit uses a 50 mm bore and a male-threaded M18x1.5 piston rod.
The short riveted body saves axial mounting depth where a larger profile cylinder will not fit. It requires only one air line and one solenoid port to drive the motion, simplifying plumbing. A fixed NBR bumper handles end-of-stroke shock, as there is no adjustable air cushion on this compact unit.
Airtac SSA Single-Acting Compact Cylinder SSA50X5B Technical Specifications
| Model | Airtac SSA Single-Acting Compact Cylinder SSA50X5B |
|---|---|
| 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.
Model Code: Airtac SSA Single-Acting Compact Cylinder SSA50X5B
| SSA | Compact single acting, push type cylinder series. |
|---|---|
| 50 | Bore size in mm. |
| ×5 | Stroke length in mm (single-acting max 30 mm). |
| S | Built-in magnet for magnetic-switch sensing (omit = none). |
| B | Male-thread piston rod (omit = female thread). |
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 SSA50X5B Is Used
Short-Stroke Part Ejection
Uses the 874.7 N net push at 0.5 MPa to eject dense machined components from a fixture quickly over a 5 mm travel distance.
Male-Thread Tool Clamping
Threads a custom clamp or tool directly onto the M18x1.5 male rod end for secure, short-throw holding in automated assembly cells.
Shallow Depth Pressing
Fits into crowded machinery where axial space is restricted, leveraging the compact riveted body to seat bearings or pins in 5 mm increments.
Is the Airtac SSA Single-Acting Compact Cylinder SSA50X5B the Right Cylinder?
When sizing this model, consider the neighbouring bores: the SSA40 yields 545.6 N at 0.5 MPa, while the SSA63 provides 1382.6 N at 0.5 MPa. This SSA50X5B sits between them, delivering 874.7 N at 0.5 MPa.
This configuration features a 50 mm bore, a 5 mm stroke, a PT1/4 port, and a male M18x1.5 rod thread. The stroke ceiling for this series is 30 mm. Because this SKU lacks the -S suffix, it has no piston magnet and cannot accept a magnetic switch. Operating pressure must be 0.2-1.0 MPa to overcome the spring. If air is lost, the spring drives the rod back to rest; it does not hold a mid-stroke load.
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 SSA50X5B FAQ
The SSA50X5B delivers 874.7 N net push at 0.5 MPa and 1267.4 N net push at 0.7 MPa. These figures already account for the internal return spring resistance.
No, this specific SKU does not include the -S magnet option, so it cannot accept reed or electronic switches. You would need the -S variant for position sensing.
