About the Airtac SCJ100 Standard Cylinder SCJ100X50-30S
The SCJ100X50-30S delivers substantial force in a compact 50 mm nominal stroke, with a 30 mm rear adjustment range for fine-tuning the stroke end without swapping the cylinder. At 0.5 MPa, it generates 3927 N of push force and 3681 N of pull force, making it a powerful solution for heavy-duty clamping and pressing tasks where the final position needs on-machine calibration.
This model includes a built-in magnet, allowing direct mounting of CMSG, DMSG, or EMSG sensors on the tie-rod barrel for precise end-of-stroke detection. The 25 mm diameter piston rod and PT1/2 ports handle high flow rates, while the 29 mm air cushion at each end decelerates the 100 mm bore piston smoothly. The body length is 245 mm.
Airtac SCJ100 Standard Cylinder SCJ100X50-30S Technical Specifications
| Model | Airtac SCJ100 Standard Cylinder SCJ100X50-30S |
|---|---|
| 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 SCJ100X50-30S Is Used
Heavy-Duty Stop Adjustment
Fine-tune the end-stop position for heavy guided tooling or pallet stops on an assembly line. The 30 mm adjustment range allows operators to dial in the exact stopping point after installation, compensating for machine frame tolerances.
Clamp Force Calibration
Used in a high-force clamping fixture where the clamp's closed position must be precisely set to avoid part damage. The rear adjusting screw lets commissioning engineers set the perfect clamping gap without changing the cylinder.
Wear Compensation on Gates
Actuates a heavy diverter gate on a conveyor system. As the gate's sealing edge wears over time, the stroke end can be extended by up to 30 mm to maintain a tight seal, maximizing service life before part replacement.
Is the Airtac SCJ100 Standard Cylinder SCJ100X50-30S the Right Cylinder?
Choose the SCJ100X50-30S when you need a robust 100 mm bore cylinder with a short, adjustable stroke for applications like heavy clamp positioning or stop-gate adjustment. If your force requirement is lower, stepping down to the 80 mm bore provides 2513 N of push force at the same pressure. For a fixed, non-adjustable stroke, the standard SC100X50 is a direct alternative, but it lacks the 30 mm field-adjustment capability.
When replacing this cylinder, match the 100 mm bore, 50 mm nominal stroke, and the -30 adjust range. Ensure the replacement has a PT1/4 port and the -S magnet option for sensor compatibility. This basic mount model uses the cylinder body for direct installation.
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 SCJ100X50-30S FAQ
At the standard 0.5 MPa operating pressure, this double-acting single-rod cylinder produces a push force of 3927 N and a pull force of 3681 N. At the maximum operating pressure of 1.0 MPa, the theoretical push force reaches 7854 N. The pull force is always lower due to the 25 mm rod reducing the piston area on the return stroke.
Yes, physically it will fit in the same space with the same mounting footprint, but the SCJ100X50-30S body is slightly longer to house the rear adjusting mechanism. It offers the advantage of a 30 mm field-adjustable stroke end, which the fixed-stroke SC does not. Ensure your application can accommodate the extra length and that you need the adjustment feature.
