About the Airtac SCJ100 Standard Cylinder SCJ100X450-10S
The AirTAC SCJ100X450-10S is a double-acting, single-rod pneumatic cylinder offering a nominal 450 mm stroke with a 10 mm rear-end adjustment range, allowing precise field tuning of the stroke end position. This 100 mm bore model delivers a substantial 3927 N of push force at 0.5 MPa, making it suitable for heavy-duty positioning tasks where fine mechanical setup is required.
Equipped with a built-in magnet (-S suffix), this cylinder is ready for direct mounting of CMSG/DMSG/EMSG sensors for electronic end-of-stroke detection. The 25 mm diameter piston rod and PT1/2 port ensure robust air flow, while the 29 mm air cushion provides smooth deceleration across its 30-800 mm/s speed range.
Airtac SCJ100 Standard Cylinder SCJ100X450-10S Technical Specifications
| Model | Airtac SCJ100 Standard Cylinder SCJ100X450-10S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø100 mm |
| Nominal stroke | 450 mm |
| Stroke adjustment | Up to 10 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 SCJ100X450-10S Is Used
End-Stop Calibration
Fine-tune the final position of a heavy sliding gate or press platen during commissioning, using the 10 mm screw adjustment to dial in exact mechanical alignment without re-mounting the cylinder.
Wear Compensation
On a conveyor diverter or pusher arm, the adjustable stroke can be periodically tweaked to compensate for gradual wear on contact pads, maintaining consistent product handling over time.
Format Changeovers
Quickly adapt the stroke end for different product sizes on a packaging or assembly station, reducing changeover time by simply turning the rear adjusting screw instead of swapping out hard stops.
Is the Airtac SCJ100 Standard Cylinder SCJ100X450-10S the Right Cylinder?
For applications requiring a 450 mm stroke with a 10 mm fine-tuning range, this SCJ100X450-10S is a direct fit. If higher force is needed, stepping up to the 125 mm bore provides 6136 N of push force at 0.5 MPa. For a fixed, non-adjustable stroke, the standard SC series is a simpler alternative. This model replaces any SCJ100 with a 450 mm nominal stroke, 10 mm adjust range, PT ports, and a magnet, using basic mounting. At this stroke length, ensure the rod is guided externally if significant side loads are present to prevent bending.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-10)
- ✓ 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 SCJ100X450-10S FAQ
At 0.5 MPa, it provides 3927 N push and 3681 N pull force. The maximum push force at the 1.0 MPa operating limit is 7068 N. The force is identical to a fixed-stroke SC100 cylinder.
A standard SC100 will fit dimensionally but lacks the rear adjusting screw. If your application requires the 10 mm field-adjustable stroke range for setup or wear take-up, you must replace it with another SCJ100X450-10S or an SCJ100 with an equivalent adjust range.
