About the Airtac SCJ100 Standard Cylinder SCJ100X450-30S
The SCJ100X450-30S is a double-acting, single-rod pneumatic cylinder with a rear adjusting screw that lets you fine-tune the stroke end by up to 30 mm on the machine. With a 100 mm bore, it delivers 3927 N of push force at 0.5 MPa, making it a robust actuator for mid-range industrial tasks where stroke calibration is critical.
A built-in magnet allows direct mounting of CMSG/DMSG/EMSG sensors on the tie-rod barrel for reliable end-of-stroke detection. The 25 mm piston rod, PT1/2 ports, and 29 mm air cushion provide smooth deceleration, while the standard TPU seals suit ambient temperatures from -20 to +70 °C.
Airtac SCJ100 Standard Cylinder SCJ100X450-30S Technical Specifications
| Model | Airtac SCJ100 Standard Cylinder SCJ100X450-30S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø100 mm |
| Nominal stroke | 450 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 SCJ100X450-30S Is Used
Format Changeovers
Quickly adjust the end stop by up to 30 mm when switching product sizes on packaging or assembly machines, eliminating mechanical stop changes.
Wear Compensation
Fine-tune the stroke end to take up mechanical wear in clamping or pressing fixtures, maintaining consistent force application over time.
Diverter Gates
Set the precise open/close position of a material-handling gate, with the 3927 N push force easily managing heavy diverting flaps.
Is the Airtac SCJ100 Standard Cylinder SCJ100X450-30S the Right Cylinder?
Choose this 100 mm bore when your application needs around 3900 N of push force at standard shop air. If you require less force, the 80 mm bore offers 2513 N; for more, the 125 mm bore steps up to 6136 N. The 30 mm adjustable stroke is ideal for commissioning trials or format changeovers without swapping the cylinder.
For replacement, match the 100 mm bore, 450 mm nominal stroke, 30 mm adjust range, PT port thread, and the built-in magnet. At this 450 mm stroke, ensure the rod is supported against side loads—consider an external guide rail or switch to a guided cylinder if lateral forces are present.
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 SCJ100X450-30S FAQ
At 0.5 MPa, it provides 3927 N pushing force and 3681 N pulling force. The maximum push force at 0.9 MPa operating pressure is 7068 N.
Yes, if you need field-adjustable stroke. It matches an SC100X450 in bore and nominal stroke, but adds a rear screw for up to 30 mm of end-position adjustment. Ensure your mounting and porting (PT1/2) are compatible.
