About the Airtac SCJ100 Standard Cylinder SCJ100X80-10
The SCJ100X80-10 is a double-acting, single-rod pneumatic cylinder that puts field-adjustable stroke control directly on the machine. Its rear-cap adjusting screw lets you fine-tune the stroke end position by up to 10 mm without removing the cylinder, making it ideal for commissioning trials and wear take-up. With a 100 mm bore, this unit generates a substantial 3927 N of push force at 0.5 MPa and uses a 25 mm diameter piston rod with a PT1/2 port.
This adjustable-stroke design uses the same robust tie-rod construction as the fixed-stroke SC series but adds a stroke-end screw in the rear cap. The body length A for this SCJ bore is 245 mm, and the standard air cushion is 29 mm. It operates on filtered air from 0.15 to 1.0 MPa across a temperature range of -20 to +70 °C, with a speed range of 30-800 mm/s.
Airtac SCJ100 Standard Cylinder SCJ100X80-10 Technical Specifications
| Model | Airtac SCJ100 Standard Cylinder SCJ100X80-10 |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø100 mm |
| Nominal stroke | 80 mm |
| Stroke adjustment | Up to 10 mm (rear adjusting screw) |
| Acting type | Double acting (single rod) |
| Port size | PT1/2 |
| 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, 29 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 (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 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 SCJ100 Standard Cylinder SCJ100X80-10 Is Used
End-Stop Calibration
The 10 mm rear screw adjustment allows operators to quickly compensate for tooling wear or material thickness changes on clamping and pressing fixtures without stopping production.
Product Diverters
Fine-tune the stroke end on a diverter gate to match different package sizes on a conveyor line, ensuring reliable product handling without mechanical modifications.
Assembly Presses
Set the exact insertion depth for a press-fit operation during setup. The adjustable stroke provides a repeatable mechanical stop, protecting parts from over-travel damage.
Is the Airtac SCJ100 Standard Cylinder SCJ100X80-10 the Right Cylinder?
Choose the SCJ100X80-10 when you need to dial in a precise end position on a 100 mm bore actuator without adding external hard stops. If your force requirement is lower, the 80 mm bore SCJ delivers 2513 N push at 0.5 MPa, offering a lighter and more compact alternative. For applications needing a longer fixed stroke with no adjustment, the standard SC100 series is a simpler, cost-effective match. This model is a direct dimensional replacement for another AirTAC SCJ100X80-10 with PT ports and basic mounting.
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 SCJ100 Standard Cylinder SCJ100X80-10 FAQ
At the standard 0.5 MPa operating pressure, this cylinder provides 3927 N of push force and 3681 N of pull force. The maximum push force at 0.9 MPa is 7068 N. The pull force is lower because the 25 mm rod reduces the effective piston area on the return stroke.
A screw in the rear cap limits how far the piston can retract, shortening the stroke end by up to 10 mm from the nominal 80 mm. This is a mechanical stroke stop, not a locking device. The cylinder will not hold a load if air pressure is lost; an external rod lock or pilot-operated check valve is required for load holding.
