About the Airtac SCJ80 Standard Cylinder SCJ80X10-10
The SCJ80X10-10 is an 80 mm bore, double-acting, single-rod pneumatic cylinder with a field-adjustable stroke. Its rear-cap screw provides up to 10 mm of stroke-end adjustment from the 10 mm nominal maximum, delivering 2513 N of push force at 0.5 MPa. The 25 mm piston rod and PT3/8 ports suit compact automation tasks requiring precise end-stop tuning.
With a body length A of 239 mm and a 28 mm air cushion, this tie-rod cylinder is built for frequent adjustment. The adjustable stroke mechanism allows operators to dial in the exact stopping position during commissioning or format changes, eliminating the need for external hard stops and reducing mechanical complexity on the line.
Airtac SCJ80 Standard Cylinder SCJ80X10-10 Technical Specifications
| Model | Airtac SCJ80 Standard Cylinder SCJ80X10-10 |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø80 mm |
| Nominal stroke | 10 mm |
| Stroke adjustment | Up to 10 mm (rear adjusting screw) |
| Acting type | Double acting (single rod) |
| Port size | PT3/8 |
| Rod thread | M20×1.5 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |
| Cushion | Adjustable, 28 mm |
| Max stroke | Up to 1500 mm |
Specifications follow the official AirTAC SCJ (adjustable-stroke) datasheet. The rear adjusting screw sets the stroke end position; force is the same as the equivalent single-rod SC bore. Confirm against the product label before installation. Thread options: PT (standard) / G.
Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 kgf | |
SCJ is single-rod, so force matches the equivalent SC bore: push uses the full bore area, pull subtracts the rod area. Actual usable force is lower than theoretical due to friction and back-pressure; size with a safety margin.

Where the Airtac SCJ80 Standard Cylinder SCJ80X10-10 Is Used
Commissioning Fine-Tuning
During machine setup, the 10 mm adjustment screw lets technicians precisely set the retract end position for sensors or grippers without remachining stops.
Wear Compensation
In high-cycle pick-and-place, the adjustable stroke compensates for gripper finger wear over time, maintaining consistent part contact without reprogramming.
Short-Stroke Stops
Acts as a precise, adjustable end-stop for small parts on a conveyor, where the 2513 N push force easily positions lightweight components.
Is the Airtac SCJ80 Standard Cylinder SCJ80X10-10 the Right Cylinder?
Choose the SCJ80X10-10 when you need to fine-tune a very short stroke end position by up to 10 mm. If the 2513 N push force at 0.5 MPa is insufficient, stepping up to the 100 mm bore provides 3927 N. For applications where the stroke never needs field adjustment, the fixed-stroke SC80 cylinder offers a simpler, more cost-effective solution. If side loads are present even on this short 10 mm stroke, consider adding an external guide rail.
This model is a direct replacement for any AirTAC SCJ80X10-10 with PT ports and basic mounting. When ordering a replacement, match the 80 mm bore, 10 mm nominal stroke, and 10 mm adjustment range. The F-SC80LB foot mount or F-SC80FA front flange can be added if the mounting style changes.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-10)
- ✓ Required force at your working pressure
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Set the rear adjusting screw, then lock it before running.
- check Adjust end cushion screws for smooth stops.
- check Use SCJ mounting accessory (FA / LB / TC / TCM1).
- check Installation by qualified personnel per AirTAC docs.
Airtac SCJ80 Standard Cylinder SCJ80X10-10 FAQ
At 0.5 MPa, the push force is 2513 N and the pull force is 2268 N. The maximum push force at the 0.9 MPa operating limit is 4523 N. Because it is a single-rod cylinder, the pull force is lower due to the rod area.
Yes, if you need the adjustable feature. The SCJ80X10-10 matches the SC80 bore and port size but its body is slightly longer to house the adjusting screw. Ensure the 10 mm adjustment range suits your application; for a pure fixed-stroke replacement, an SC80X10 is a direct fit.
