Airtac SSA Single-Acting Compact Cylinder SSA50X10
The AirTAC Airtac SSA Single-Acting Compact Cylinder SSA50X10 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 SSA50X10
The AirTAC SSA50X10 is a compact single-acting push-type cylinder where air pressure extends the rod and an internal spring retracts it. It delivers 874.7 N of net push at 0.5 MPa, providing robust force for short-stroke tasks. Because the spring handles the return motion, you only need one air line and one solenoid port, which cuts down on fittings and simplifies valve requirements.
This model features a 50 mm bore, a 10 mm stroke, and a short riveted body that saves axial mounting depth in crowded machinery. The 20 mm piston rod uses a PT1/4 port and an M10x1.5 female rod-end thread. It relies on a fixed NBR bumper to decelerate at the stroke end, rather than an adjustable air cushion. Note that this specific SKU lacks a piston magnet, so it cannot accept magnetic switches without upgrading to the -S variant.
Airtac SSA Single-Acting Compact Cylinder SSA50X10 Technical Specifications
| Model | Airtac SSA Single-Acting Compact Cylinder SSA50X10 |
|---|---|
| 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.

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 SSA50X10 Is Used
Heavy-Duty Stamping
Provides 874.7 N of net push at 0.5 MPa to drive short-stroke stamping pins in dense metalworking fixtures.
Pallet Diverter
Extends rapidly to push heavy pallets onto a secondary line, relying on the internal spring to retract quickly out of the way.
Carton Ejection
Uses its compact 10 mm stroke and 50 mm bore to eject packed cartons from a packaging station without consuming valuable axial space.
Is the Airtac SSA Single-Acting Compact Cylinder SSA50X10 the Right Cylinder?
When sizing this unit, consider the neighboring bores to ensure optimal performance. Stepping down to the SSA40 yields 545.6 N of net push at 0.5 MPa, while stepping up to the SSA63 provides 1382.6 N at the same pressure. Based on the 874.7 N output at 0.5 MPa, a safe working load is roughly 525 N (about 60 percent of capacity), allowing a vertical lift of approximately 44.6 kg with a 2:1 safety margin.
Remember that the standard stroke ceiling for this series is 30 mm. Because it is spring-returned, the SSA50X10 will not hold a mid-stroke load if air pressure drops; the spring drives the rod back to its retracted rest position. Confirm your requirements for the 50 mm bore, 10 mm stroke, PT1/4 port, female M10x1.5 rod thread, and the absence of a magnet before ordering.
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 SSA50X10 FAQ
The SSA50X10 provides 874.7 N of net push force at 0.5 MPa and 1267.4 N at 0.7 MPa. These figures already account for the force lost to overcoming the internal return spring.
No, this specific SKU does not include a piston magnet. To use AirTAC reed or electronic switches, you must select the -S variant. Additionally, it requires a minimum operating pressure of 0.2 MPa to overcome the return spring.
