About the Airtac SCJ63 Standard Cylinder SCJ63X100-10
The SCJ63X100-10 is a double-acting, single-rod pneumatic cylinder that puts fine stroke-end adjustment directly on the machine. Its rear-cap screw lets you shorten the stroke by up to 10 mm without removing the cylinder, which is a practical time-saver during commissioning or format changes. With a 20 mm rod, PT1/4 ports, and a 28 mm air cushion, this 63 mm bore unit delivers 1559 N of push force at 0.5 MPa, scaling to 2805 N at the 0.9 MPa maximum operating pressure.
Because the stroke is field-adjustable, you can dial in the exact end position to compensate for wear, tooling variations, or slight fixture misalignment. The SCJ shares the same mounting accessories as the fixed-stroke SC series—basic, FA front flange, LB foot, or TC centre trunnion—so it drops into existing setups with minimal rework. This model is basic mount, TPU seal, and PT thread, ready for standard industrial air service from -20 to +70 °C.
Airtac SCJ63 Standard Cylinder SCJ63X100-10 Technical Specifications

| Nominal stroke | 100 mm |
| Stroke adjustment | Up to 10 mm (rear adjusting screw) |
| Acting type | Double acting (single rod) |
| Port size | PT1/4 |
| Rod thread | M16×1.5 |
| 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, 28 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 (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | — |
| Max (@1.0 MPa) | 318 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 SCJ63 Standard Cylinder SCJ63X100-10 Is Used
End-Stop Fine Tuning
Dial in the precise stopping position of a pusher or ejector during machine commissioning. The 10 mm adjustment screw lets technicians compensate for stack-up tolerances without shimming or re-machining the mounting bracket.
Wear Take-Up on Stops
On a conveyor gate or diverter, the rubber stop bumper compresses over time. The adjustable stroke lets operators restore the exact gate position in seconds by turning the rear screw, keeping product flow consistent.
Format Changeover
When a packaging line switches between box sizes, the SCJ63X100-10 can be quickly re-set to a new stroke end for the flap folder or label applicator, reducing changeover downtime compared to swapping fixed-stroke cylinders.
Is the Airtac SCJ63 Standard Cylinder SCJ63X100-10 the Right Cylinder?
Choose the SCJ63 when you need mid-range force and the ability to tweak the stroke end on the fly. At 0.5 MPa, the 63 mm bore generates 1559 N push, which is a clear step up from the 40 mm bore's 628 N and sits comfortably below the 80 mm bore's 2513 N. If your application requires a fixed, repeatable stroke with no adjustment, the standard SC63 fixed-stroke cylinder is a simpler, more cost-effective alternative. For a drop-in replacement, match the 63 mm bore, 100 mm nominal stroke, 10 mm adjust range, PT port thread, and basic mounting style exactly—an SCJ63X100-10 from AirTAC ensures the same body length, rod thread, and cushion performance.
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 SCJ63 Standard Cylinder SCJ63X100-10 FAQ
The cylinder's output force depends only on bore size and air pressure, not the stroke adjustment. At 0.5 MPa, it generates 1559 N push and 1402 N pull (pull is lower because the 20 mm rod reduces the piston area on the return side). At the maximum operating pressure of 0.9 MPa, push force reaches 2805 N. The rear adjusting screw only sets the stroke end position within the 10 mm range.
Yes, provided the original unit matches the 63 mm bore, 100 mm nominal stroke, 10 mm adjustable range, PT port thread, and basic mounting style. The SCJ is a tie-rod cylinder, so it is not dimensionally interchangeable with ISO 15552 profiles. For a guaranteed fit, also verify the rod thread (M16x1.5) and the body length A(SCJ) of 197 mm plus stroke.
