About the Airtac SCJ100 Standard Cylinder SCJ100X50-30STC
The SCJ100X50-30STC is a 100 mm bore, double-acting, single-rod pneumatic cylinder with a field-adjustable stroke. A rear-cap adjusting screw lets you shorten the stroke end by up to 30 mm without replacing the cylinder, delivering 3927 N of push force at 0.5 MPa. The 25 mm piston rod, PT1/2 ports, and 29 mm air cushion make it a robust workhorse for heavy-duty positioning tasks.
This model includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors and a centre trunnion mount (TC) with the TCM1 bracket for pivoting applications. The tie-rod construction and TPU seals suit standard temperatures from -20 to +70 °C, providing a genuine AirTAC solution for dynamic stroke-end tuning in industrial machinery.
Airtac SCJ100 Standard Cylinder SCJ100X50-30STC Technical Specifications
| Model | Airtac SCJ100 Standard Cylinder SCJ100X50-30STC |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø100 mm |
| Nominal stroke | 50 mm |
| Stroke adjustment | Up to 30 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 SCJ100X50-30STC Is Used
Commissioning & Process Setup
Fine-tune the end position of a heavy clamp or stop during machine commissioning. The 30 mm adjustment range allows engineers to dial in the exact stroke without swapping shims or cylinders, speeding up line setup.
Format Changeover on Packaging Lines
Adjust the stroke of a pusher or diverter arm when switching between product sizes. The rear screw provides quick, repeatable adjustments, minimizing downtime during format changes on cartoners or palletizers.
Wear Compensation in Heavy Tooling
Compensate for wear on a bending die or pressing tool by slightly extending the stroke end. This maintains consistent part quality over the tool's life without reprogramming the PLC or replacing mechanical stops.
Is the Airtac SCJ100 Standard Cylinder SCJ100X50-30STC the Right Cylinder?
Choose the SCJ100 when you need substantial force—3927 N push at 0.5 MPa—and the ability to dial in the stroke end on the machine. If your force requirement is lower, stepping down to an SCJ80 bore reduces push force to 2513 N at the same pressure. For applications requiring a fixed, non-adjustable stroke, the standard SC100 cylinder is a more economical choice.
This SCJ100X50-30STC is a direct replacement for another AirTAC SCJ100 adjustable-stroke cylinder with a 50 mm nominal stroke, 30 mm adjust range, PT ports, centre trunnion (TC) mounting, and a magnetic piston. For strokes of 300 mm or more, assess side-loading on the 25 mm rod and consider an external guide or a guided cylinder to prevent rod bending.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-30)
- ✓ 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 SCJ100X50-30STC FAQ
As a single-rod cylinder, push and pull forces differ. At 0.5 MPa, the theoretical push force is 3927 N and the pull force is 3681 N. At the maximum operating pressure of 0.9 MPa, push force reaches 7068 N. The adjusting screw only changes the stroke end position and does not alter the cylinder's force output.
Yes, this is a direct replacement for any AirTAC SCJ100 adjustable-stroke cylinder with a 50 mm nominal stroke, 30 mm adjustment range, PT ports, centre trunnion (TC) mounting, and a magnetic piston. Ensure your existing mounting matches the F-SC100TC trunnion bracket and that the sensor type is compatible with the built-in magnet.
