Airtac SSA Single-Acting Compact Cylinder SSA32X5S
The AirTAC Airtac SSA Single-Acting Compact Cylinder SSA32X5S 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 SSA32X5S
The AirTAC SSA32X5S is a compact single-acting push-type cylinder where air extends the rod and an internal spring retracts it. It delivers 346.6 N of net push at 0.5 MPa, making it ideal for very short 5 mm ejection motions. Because the quoted force is already net of the return spring, you can size directly to this real design figure without manual subtraction.
This model features a built-in piston magnet (-S) for AirTAC reed or electronic switches, fitting neatly into the body sensor grooves. The short riveted body saves axial mounting depth in crowded fixtures, while the fixed NBR bumper absorbs end-of-stroke shock without requiring adjustable cushioning.
Airtac SSA Single-Acting Compact Cylinder SSA32X5S Technical Specifications
| Model | Airtac SSA Single-Acting Compact Cylinder SSA32X5S |
|---|---|
| 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 SSA32X5S Is Used
Short-Stroke Part Ejection
Uses the 346.6 N net push to positively eject machined components from a fixture in just 5 mm, saving axial space.
Transfer Line Diverter
Employs the internal return spring to retract the 12 mm rod automatically when air is removed, simplifying valve requirements.
PCB Edge Clamping
Secures delicate boards with a safe working load of 208 N, using the fixed NBR bumper to prevent harsh impact.
Is the Airtac SSA Single-Acting Compact Cylinder SSA32X5S the Right Cylinder?
When sizing this 32 mm bore unit, consider the neighboring bores at 0.5 MPa: stepping down to the SSA25 yields 216.9 N net push, while stepping up to the SSA40 provides 545.6 N. This SSA32X5S provides a safe working load of roughly 208 N (about 60% of its 346.6 N capacity) and can vertically lift approximately 17.7 kg with a 2:1 safety margin.
This configuration includes a 5 mm stroke, a PT1/8 port, a Ø12 mm rod, and a female M6x1.0 rod-end thread (male M10x1.25 available with a B suffix). Remember the 30 mm maximum standard stroke ceiling. Because the spring drives retraction on air loss, this cylinder will not hold a mid-stroke load; use an external rod lock if position holding is required.
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 SSA32X5S FAQ
This single-acting push cylinder provides 346.6 N of net push at 0.5 MPa and 507.5 N at 0.7 MPa. It requires a minimum operating pressure of 0.2 MPa to overcome the internal return spring.
No, the internal spring drives the rod back to its retracted rest position on air loss. It does not hold a mid-stroke load. The -S magnet allows tracking via reed or electronic switches, but external locking is needed for holding.
