About the Airtac SCJ100 Standard Cylinder SCJ100X30-30S
The AirTAC SCJ100X30-30S is a double-acting, single-rod pneumatic cylinder with a field-adjustable stroke end, giving you a 30 mm fine-tuning range on the nominal 100 mm stroke. Its 25 mm rod generates 3927 N of push force at 0.5 MPa, making it a capable actuator for medium-to-heavy industrial tasks where the final stop position needs on-machine tweaking.
A built-in magnet (the -S suffix) lets you mount CMSG, DMSG, or EMSG reed and solid-state sensors directly onto the tie-rod barrel for contactless end-of-stroke or mid-stroke position feedback. The 100 mm bore body is 245 mm long (A dimension), and the rear adjusting screw shortens the stroke end without altering the cylinder's 0.15–1.0 MPa operating envelope or its 1500 mm maximum standard stroke capability.
Airtac SCJ100 Standard Cylinder SCJ100X30-30S Technical Specifications
| Model | Airtac SCJ100 Standard Cylinder SCJ100X30-30S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø100 mm |
| Nominal stroke | 30 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 SCJ100X30-30S Is Used
Commissioning & Setup
Dial in the exact stop position during machine bring-up with the 30 mm rear screw adjustment, eliminating the need to shim or reposition the entire cylinder body.
Clamping & Pressing
Fine-tune the pressing depth or clamping gap on a fixture using the adjustable stroke end, then monitor piston position with the built-in magnet and a DMSG sensor.
Product Stops & Diverters
Adjust the retracted stop point of a diverter gate to handle different package sizes without swapping the cylinder, speeding up format changeovers on a packaging line.
Is the Airtac SCJ100 Standard Cylinder SCJ100X30-30S the Right Cylinder?
Step up to the SCJ125 if your application demands more than the 3927 N push force this 100 mm bore delivers at 0.5 MPa—the 125 mm bore provides 6136 N. If you never need to alter the stroke after installation, the fixed-stroke SC100 is a simpler, cost-effective alternative. For a direct replacement, match the 100 mm bore, 30 mm nominal stroke, 30 mm adjust range, PT port thread, basic mounting, and the integrated magnet (-S).
At a 30 mm stroke, rod bending from side loads is rarely a concern, but if your tooling applies any off-axis force, an external guide rail or a guided cylinder will protect the rod bearing and piston seals from premature wear.
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 SCJ100X30-30S FAQ
At 0.5 MPa, the push force is 3927 N and the pull force is 3681 N (the difference is due to the single 25 mm rod). At the maximum operating pressure of 1.0 MPa, the theoretical push force reaches 7854 N.
Yes, if you need the 30 mm adjustable stroke range. The SCJ shares the same mounting footprint and port size (PT1/2) as the SC100. Ensure your mounting style and magnet option match; this -S model requires sensor compatibility.
