Airtac SSA Single-Acting Compact Cylinder SSA12X30B
The AirTAC Airtac SSA Single-Acting Compact Cylinder SSA12X30B is a genuine single-acting COMPACT cylinder (single acting, push type) with a Ø12mm bore and 30mm 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 SSA12X30B
The AirTAC SSA12X30B is a compact single-acting push-type cylinder where air pressure extends the rod and an internal spring retracts it. This 12 mm bore model yields 46.5 N of net push at 0.5 MPa, with the return spring force already subtracted for accurate sizing. It reaches the 30 mm maximum standard stroke limit for this series.
Featuring a male-thread M5x0.8 piston rod, this unit simplifies plumbing by requiring only a single M5x0.8 air line and one solenoid port. The short riveted body minimizes axial mounting depth in crowded fixtures, and a fixed NBR bumper absorbs end-of-stroke shock without adjustable cushions.
Airtac SSA Single-Acting Compact Cylinder SSA12X30B Technical Specifications
| Model | Airtac SSA Single-Acting Compact Cylinder SSA12X30B |
|---|---|
| Series | SSA compact single-acting cylinder |
| Bore size | Ø12 mm |
| Stroke | 30 mm |
| Acting type | Single acting, push type |
| Port size | M5×0.8 |
| Rod end thread | M3×0.5 female / M5×0.8 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 (Ø12mm, Push)
| Pressure | Push force (net) |
|---|---|
| 0.5 MPa | 47 N |
| 0.7 MPa | 69 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 SSA12X30B Is Used
Small Part Ejection
Uses the 46.5 N push stroke to eject small machined components from a fixture without requiring complex double-acting plumbing.
Product Diverting
The short 30 mm stroke and compact riveted body fit alongside conveyors to push lightweight packages onto a secondary routing lane.
Light Duty Clamping
Applies spring-return clamping pressure via the male M5x0.8 rod end, automatically releasing the workpiece when air pressure is removed.
Is the Airtac SSA Single-Acting Compact Cylinder SSA12X30B the Right Cylinder?
When sizing this bore, verify your motion needs against the 46.5 N net push at 0.5 MPa. If less force is acceptable, stepping down is not an option as 12 mm is the smallest available. Stepping up to the SSA16 provides 80.5 N at 0.5 MPa. Keep in mind the 30 mm stroke ceiling; this model sits exactly at that maximum standard limit.
This configuration includes the B option for a male M5x0.8 rod thread and lacks the S magnet, meaning it cannot support magnetic switches. Operating pressure must be 0.2-1.0 MPa to overcome the spring. Because the spring drives retraction on air loss, it will not hold a mid-stroke load without external locking.
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 SSA12X30B FAQ
This single-acting model provides a net push force of 46.5 N at 0.5 MPa and 69.2 N at 0.7 MPa. These figures already account for the internal return spring resistance.
No, this specific SKU lacks the S option for a built-in piston magnet, so it cannot accept reed or electronic switches. The cylinder also requires a minimum of 0.2 MPa operating pressure to overcome the spring.
