About the Airtac SCJ100 Standard Cylinder SCJ100X300-100
The SCJ100X300-100 is a double-acting, single-rod pneumatic cylinder that puts 3927 N of push force at 0.5 MPa behind a 25 mm diameter piston rod. Its defining feature is the rear-cap adjusting screw, which lets you shorten the stroke end by up to 100 mm without removing the cylinder from the machine—ideal for commissioning trials or format changeovers where the exact travel needs to be dialled in on the fly.
With a 29 mm air cushion at each end and a body length A of 245 mm, this 100 mm bore actuator handles operating pressures from 0.15 to 1.0 MPa. At the maximum 0.9 MPa operating pressure, push thrust reaches 7068 N. The PT1/2 port and M20x1.5 rod thread keep connections straightforward in standard industrial setups.
Airtac SCJ100 Standard Cylinder SCJ100X300-100 Technical Specifications
| Model | Airtac SCJ100 Standard Cylinder SCJ100X300-100 |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø100 mm |
| Nominal stroke | 300 mm |
| Stroke adjustment | Up to 100 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 SCJ100X300-100 Is Used
Commissioning & Setup
Field-adjust the stroke end by up to 100 mm during machine commissioning. Fine-tune the stop position without swapping cylinders or machining external hard stops, cutting setup time on new production lines.
Product Format Changeover
When a packaging line switches between box sizes or pallet patterns, the rear screw lets operators quickly reset the cylinder's end position. The 100 mm adjustment range covers multiple formats with a single actuator.
Wear Compensation
In high-cycle clamping or pressing stations, tooling wear gradually shifts the stop point. The SCJ100X300-100 lets maintenance teams dial the stroke back to the correct position without dismantling the tooling or replacing the cylinder.
Is the Airtac SCJ100 Standard Cylinder SCJ100X300-100 the Right Cylinder?
Choose the SCJ100X300-100 when you need the 3927 N push force of a 100 mm bore but also require on-machine stroke fine-tuning. If your force requirement drops closer to 2513 N, stepping down to an 80 mm bore SCJ saves air and space. For applications where the stroke is fixed and never needs adjustment, the standard SC100X300 fixed-stroke cylinder is a simpler, lower-cost alternative.
At 300 mm of stroke, side-loading can bend the 25 mm rod or wear the bushing. If the load is not guided externally, add a guide rail or switch to a guided cylinder. For a drop-in replacement, match the 100 mm bore, 300 mm nominal stroke, 100 mm adjust range, PT port thread, and the same basic mounting configuration.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-100)
- ✓ 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 SCJ100X300-100 FAQ
At 0.5 MPa, push force is 3927 N and pull force is 3681 N (the difference is due to the 25 mm rod area). At the maximum operating pressure of 0.9 MPa, push reaches 7068 N. The adjusting screw changes only the stroke end position, not the force.
Yes, provided the mounting and port thread match. The SCJ body is slightly longer to house the adjusting screw, but the bore, rod, and force ratings are identical. Ensure the 100 mm adjustment range does not interfere with your machine structure.
