About the Airtac SCJ100 Standard Cylinder SCJ100X80-75SH
The SCJ100X80-75SH is a double-acting, single-rod pneumatic cylinder with a field-adjustable stroke, delivering a substantial 3927 N of push force at 0.5 MPa. Its rear-cap adjusting screw provides a 75 mm range to fine-tune the stroke end position, making it ideal for applications requiring precise end-stop calibration without swapping the cylinder. The 100 mm bore uses a 25 mm piston rod and PT1/2 ports, with a body length A of 245 mm.
This model is equipped with a built-in magnet (S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, enabling reliable end-of-stroke detection. The H suffix specifies a Viton (FKM) seal, which extends the operating temperature range to 0–150°C, making it suitable for high-temperature or aggressive environments where standard seals would fail.
Airtac SCJ100 Standard Cylinder SCJ100X80-75SH Technical Specifications
| Model | Airtac SCJ100 Standard Cylinder SCJ100X80-75SH |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø100 mm |
| Nominal stroke | 80 mm |
| Stroke adjustment | Up to 75 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 SCJ100X80-75SH Is Used
Hot Press End-Stop Adjustment
In a heated laminating or forming press, the Viton seals withstand 150°C while the 75 mm adjustment screw allows operators to fine-tune the platen's closed position for different material thicknesses.
Automated Welding Fixture
The 3927 N push force clamps heavy weldments securely. The adjustable stroke compensates for fixture wear or different part batches, and the magnetic piston provides sensor confirmation of clamp engagement.
High-Temp Diverter Gate
Controls a diverter on a conveyor in a drying oven. The 75 mm adjust range sets the gate's end stop precisely, while the Viton seal ensures long life in the continuous high-temperature environment.
Is the Airtac SCJ100 Standard Cylinder SCJ100X80-75SH the Right Cylinder?
Choose the SCJ100X80-75SH when you need high force in a compact stroke length with the ability to dial in the exact stroke end on the machine. If your force requirement is lower, stepping down to an 80 mm bore (2513 N push at 0.5 MPa) can reduce air consumption and cost. For applications needing a fixed, non-adjustable stroke, the standard SC series is a more economical choice. This cylinder is a direct replacement for another AirTAC SCJ100 cylinder with an 80 mm nominal stroke, 75 mm adjust range, PT ports, a magnet, and a Viton seal.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-75)
- ✓ 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 SCJ100X80-75SH FAQ
At the standard operating pressure of 0.5 MPa, this 100 mm bore cylinder provides a push force of 3927 N and a pull force of 3681 N. The maximum push force at 0.9 MPa is 7068 N. The pull force is lower due to the area of the 25 mm piston rod.
The stroke is adjusted via a screw in the rear end cap. This screw acts as a physical stop for the piston, allowing you to shorten the stroke end by up to 75 mm from the nominal 80 mm maximum. It is a mechanical adjustment for position, not a force or speed control.
