About the Airtac SCJ100 Standard Cylinder SCJ100X350-10S
The SCJ100X350-10S is a double-acting, single-rod pneumatic cylinder with a field-adjustable stroke end, letting you fine-tune the piston stop position by up to 10 mm without removing the unit. With a 100 mm bore and 25 mm rod, it delivers a substantial 3927 N of push force at 0.5 MPa, making it a strong candidate for heavy pressing, clamping, and positioning tasks where the final stroke length needs on-machine dial-in.
This model includes a built-in magnet (S suffix), so CMSG, DMSG, or EMSG solid-state and reed sensors clip directly onto the tie-rod barrel for reliable end-of-stroke or mid-stroke position feedback. The body length A(SCJ) is 245 mm, and the adjustable air cushion at each end decelerates the 25 mm rod smoothly, protecting tooling during high-cycle operation.
Airtac SCJ100 Standard Cylinder SCJ100X350-10S Technical Specifications
| Model | Airtac SCJ100 Standard Cylinder SCJ100X350-10S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø100 mm |
| Nominal stroke | 350 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 SCJ100X350-10S Is Used
End-Stop Commissioning
During machine setup, the 10 mm rear adjusting screw lets technicians dial in the exact clamp or press depth for new tooling without shimming or swapping cylinders, cutting commissioning time.
Heavy-Part Clamping
In a welding or assembly fixture, the 3927 N push force holds large fabrications securely. The adjustable stroke compensates for part tolerance variations, ensuring consistent clamp pressure.
Wear Take-Up on Press Tools
On a punch or forming press, the stroke end can be advanced by up to 10 mm to compensate for tool wear or die sharpening, maintaining the correct bottom-dead-centre position without mechanical rework.
Is the Airtac SCJ100 Standard Cylinder SCJ100X350-10S the Right Cylinder?
Choose the SCJ100 when your application needs roughly 3900 N of push force at standard shop air. If you need more force, stepping up to the 125 mm bore delivers 6136 N push at 0.5 MPa; for a lighter, more compact solution, the 80 mm bore provides 2513 N. The 10 mm adjustment range is ideal for fine end-stop tuning; if your process requires a wider adjustment window, consider a -20 or -50 adjust variant. For a fixed-stroke application without the rear screw, the standard SC100 cylinder is a simpler, lower-cost alternative. At 350 mm of stroke, the rod is extended significantly—evaluate side-loading carefully and consider an external guide rail or a guided cylinder if the load is not perfectly axial. A direct replacement must match the 100 mm bore, 350 mm nominal stroke, 10 mm adjust range, PT port thread, and the built-in magnet.
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 SCJ100X350-10S FAQ
At 0.5 MPa, the push force is 3927 N and the pull force is 3681 N (the pull force is lower because the 25 mm rod reduces the effective piston area on the return stroke). At the maximum operating pressure of 0.9 MPa, the push force reaches 7068 N.
Yes, if you need the ability to fine-tune the stroke end. The SCJ100 shares the same mounting accessories (FA, LB, TC) and port size (PT1/2) as the SC100, but the overall body length is slightly longer to accommodate the adjusting screw. Ensure your mounting space can accept the 245 mm body length A(SCJ) and that the 10 mm adjustment range covers your stroke variation.
