Airtac SSA Single-Acting Compact Cylinder SSA32X5B
The AirTAC Airtac SSA Single-Acting Compact Cylinder SSA32X5B is a genuine single-acting COMPACT cylinder (single acting, push type) with a Ø32mm 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 SSA32X5B
The AirTAC SSA32X5B is a compact single-acting push-type cylinder where air pressure extends the rod and an internal spring retracts it. At 0.5 MPa it provides 346.6 N of net push output, with the return spring force already subtracted from the raw air force. This 32 mm bore unit uses a 12 mm piston rod and requires only one air line and one solenoid port, simplifying valve and plumbing requirements for short-stroke ejection tasks.
This specific SKU features a male M10x1.25 threaded rod end and a very short 5 mm stroke. The riveted body design minimizes axial mounting depth in crowded fixtures. 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, needing at least 0.2 MPa to overcome the internal spring.
Airtac SSA Single-Acting Compact Cylinder SSA32X5B Technical Specifications
| Model | Airtac SSA Single-Acting Compact Cylinder SSA32X5B |
|---|---|
| Series | SSA compact single-acting cylinder |
| Bore size | Ø32 mm |
| Stroke | 5 mm |
| Acting type | Single acting, push type |
| Port size | PT1/8 |
| Rod end thread | M6×1.0 female / M10×1.25 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 (Ø32mm, Push)
| Pressure | Push force (net) |
|---|---|
| 0.5 MPa | 347 N |
| 0.7 MPa | 508 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 SSA32X5B Is Used
Short-Stroke Part Ejection
Uses the 346.6 N net push at 0.5 MPa to positively eject machined components from a fixture in a fraction of a second.
Male-Thread Tool Clamping
Leverages the M10x1.25 male rod end to securely thread on a custom clamp face, holding workpieces firmly during light assembly.
Shallow Depth Insertion
Fits into tight automated machinery footprints using the compact riveted body and 5 mm stroke to press small pins or rivets.
Is the Airtac SSA Single-Acting Compact Cylinder SSA32X5B the Right Cylinder?
When sizing this model, the 346.6 N net push at 0.5 MPa yields a safe working load of roughly 208 N at a 60 percent margin, or a vertical lift capacity of about 17.7 kg with a 2:1 safety factor. If less force is required, the neighboring SSA25 bore provides 216.9 N at 0.5 MPa. For heavier pushing demands, stepping up to the SSA40 bore offers 545.6 N at 0.5 MPa.
This configuration has a 5 mm stroke, well under the 30 mm standard maximum. It includes the male M10x1.25 rod thread (option B) and uses a PT1/8 port. Because this SKU lacks the S option, it has no piston magnet and cannot accept reed or electronic switches. Remember that upon air loss the spring drives the rod to its retracted rest position, so it cannot hold a mid-stroke load without an external locking device.
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 SSA32X5B FAQ
The net push force is 346.6 N at 0.5 MPa and 507.5 N at 0.7 MPa. These figures already account for the internal return spring resistance, giving you the true usable output for your design calculations.
No, this specific SKU does not include a piston magnet. To use AirTAC reed or electronic switches, you must select the -S variant. Additionally, because it is spring-return, it requires a minimum of 0.2 MPa operating pressure to overcome the spring.
