About the Airtac SCJ100 Standard Cylinder SCJ100X30-10S
The SCJ100X30-10S is a 100 mm bore double-acting single-rod cylinder with a rear adjusting screw that provides up to 10 mm of field-adjustable stroke reduction. This model delivers a push force of 3927 N at 0.5 MPa and 7068 N at 0.9 MPa, making it a compact powerhouse for applications where the end position needs fine-tuning after installation.
Equipped with a built-in magnet (-S suffix), this cylinder allows direct mounting of CMSG, DMSG, or EMSG sensors along the tie-rod barrel for precise end-of-stroke detection. The 25 mm diameter rod and PT1/2 ports handle high flow, while the 29 mm air cushion decelerates the piston smoothly. The body length A(SCJ) is 245 mm.
Airtac SCJ100 Standard Cylinder SCJ100X30-10S Technical Specifications
| Model | Airtac SCJ100 Standard Cylinder SCJ100X30-10S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø100 mm |
| Nominal stroke | 30 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 SCJ100X30-10S Is Used
End-Stop Calibration
Fine-tune the final position of a 100 mm bore press or clamping fixture during initial setup, using the 10 mm adjustment screw to dial in the exact stop point without reprogramming the controller.
Wear Compensation
On a conveyor diverter gate, use the adjustable stroke to compensate for wear on a rubber stop pad over time, maintaining consistent gate alignment without replacing the cylinder or adding shims.
Short-Stroke Format Change
Quickly adjust the retract position of a 100 mm bore ejector cylinder for different product thicknesses on a packaging line, using the rear screw to set the stroke end within the 10 mm range.
Is the Airtac SCJ100 Standard Cylinder SCJ100X30-10S the Right Cylinder?
Choose the SCJ100X30-10S when you need a 100 mm bore cylinder with a short 30 mm nominal stroke and the ability to dial back the end position by up to 10 mm during commissioning. If 3927 N of push force at 0.5 MPa is more than required, stepping down to the 80 mm bore (2513 N push) saves space and air consumption. For a fixed, non-adjustable stroke, the standard SC100 series is a simpler alternative.
This cylinder is a direct replacement for an existing AirTAC SCJ100X30-10S with a PT port, basic mounting, and a magnet. Ensure the replacement matches the bore, nominal stroke, and the 10 mm adjustment range. For strokes significantly longer than 30 mm, consider an external guide or a guided cylinder to protect the 25 mm rod from side loads.
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 SCJ100X30-10S FAQ
At 0.5 MPa, the push force is 3927 N and the pull force is 3681 N. At the maximum operating pressure of 1.0 MPa, the theoretical push force is 7068 N. The pull force is lower due to the 25 mm piston rod area.
You can, but the SCJ body is slightly longer to accommodate the adjusting screw. The SCJ100X30-10S is a direct replacement for another SCJ100X30-10S with a magnet. To replace a fixed-stroke SC, ensure the 30 mm nominal stroke and PT1/2 ports match, and that you have space for the longer body length A(SCJ) of 245 mm.
