About the Airtac SCJ100 Standard Cylinder SCJ100X300-30TC
The SCJ100X300-30TC is a double-acting, single-rod tie-rod cylinder that puts stroke-end fine-tuning directly on the machine. With a 100 mm bore and a nominal 300 mm stroke, it delivers a push force of 3927 N at 0.5 MPa, scaling up to 7068 N at the maximum operating pressure of 0.9 MPa. The rear-cap adjusting screw provides a 30 mm field-adjustable range, letting you dial in the exact stroke end position without swapping the cylinder or adding external hard stops.
This model is configured with a centre trunnion (TC) mount, supplied with the TCM1 bracket, making it ideal for applications where the cylinder body needs to pivot during operation. It uses a 25 mm piston rod, PT1/2 ports, and a standard TPU seal for reliable performance from -20 to +70 °C. The body length A(SCJ) is 245 mm, and the pneumatic cushion is 29 mm long to decelerate the piston smoothly.
Airtac SCJ100 Standard Cylinder SCJ100X300-30TC Technical Specifications
| Model | Airtac SCJ100 Standard Cylinder SCJ100X300-30TC |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø100 mm |
| Nominal stroke | 300 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 SCJ100X300-30TC Is Used
Process Tuning
Fine-tune the end position of a material stop or clamp during initial machine setup without mechanical rework, using the 30 mm screw adjustment.
Sorting Gate Actuator
Pivot a diverter gate on a conveyor line with the TC mount, and adjust the gate's open angle precisely via the rear stroke-end screw.
Format Changeover
Quickly adapt a packaging machine's push stroke for a new box size by turning the rear adjuster, avoiding a full cylinder swap.
Is the Airtac SCJ100 Standard Cylinder SCJ100X300-30TC the Right Cylinder?
Choose the SCJ100X300-30TC when your application demands a powerful 100 mm bore linear drive with the ability to tweak the stroke end position by up to 30 mm during commissioning or changeovers. If your force calculation falls short, stepping up to the 125 mm bore provides 6136 N of push at 0.5 MPa. For a simpler, fixed-stroke solution without the rear adjuster, the standard SC100X300 cylinder is the direct alternative. A direct replacement must match the 100 mm bore, 300 mm nominal stroke, 30 mm adjust range, PT port thread, and the TC centre trunnion mounting configuration. For this 300 mm stroke length, be mindful of side loads on the 25 mm rod; if the load is not guided externally, consider adding an external guide rail or switching to a guided cylinder to prevent rod bending and premature seal 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 SCJ100X300-30TC FAQ
At 0.5 MPa, it delivers 3927 N of push force and 3681 N of pull force. The push force increases to 7068 N at the maximum operating pressure of 0.9 MPa.
Yes, if you need the field-adjustable stroke feature. The SCJ100X300-30TC is dimensionally compatible with the SC series for the same bore and mount, but the body is slightly longer to house the adjusting screw. Ensure the 30 mm adjustment range and TC mount match your requirements.
