About the Airtac SCJ63 Standard Cylinder SCJ63X100-30H
The SCJ63X100-30H 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 end by up to 30 mm without removing the cylinder, which is invaluable during commissioning or format changeovers. With a 20 mm rod and a 28 mm air cushion, it handles 1559 N of push force at 0.5 MPa and can reach 2805 N at 0.9 MPa.
This variant is fitted with Viton (FKM) seals, extending the operating temperature range to 0–150 °C for hot or aggressive environments. The body length A(SCJ) is 197 mm, and the standard PT1/4 ports keep plumbing straightforward. It is a genuine AirTAC adjustable-stroke cylinder built for repeatable, fine-tuned end positions in demanding thermal conditions.
Airtac SCJ63 Standard Cylinder SCJ63X100-30H Technical Specifications
| Model | Airtac SCJ63 Standard Cylinder SCJ63X100-30H |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø63 mm |
| Nominal stroke | 100 mm |
| Stroke adjustment | Up to 30 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 SCJ63X100-30H Is Used
Hot-Process End-Stop Tuning
In ovens or autoclaves operating up to 150 °C, the Viton seals and 30 mm adjustment screw allow operators to fine-tune the material stop position without disassembling the hot tooling.
Wear Take-Up on Clamping Fixtures
When clamp pads wear over time, the rear screw can be turned to extend the effective stroke slightly, maintaining consistent clamping force without replacing the cylinder or adding shims.
Product Format Changeover
On a packaging line running different box sizes, the 30 mm adjustment range lets a technician quickly dial in a new pusher end position, minimizing downtime between batches.
Is the Airtac SCJ63 Standard Cylinder SCJ63X100-30H the Right Cylinder?
Step up to an 80 mm bore SCJ if your application needs more than 1559 N of push force at 0.5 MPa—the SCJ80 delivers 2513 N. For purely fixed-stroke tasks where no field adjustment is needed, the standard SC63 is a simpler, cost-effective alternative. If you require a direct replacement, match the 63 mm bore, 100 mm nominal stroke, 30 mm adjustment range, PT port thread, and Viton seal material exactly.
At a 100 mm stroke, rod bending is rarely a concern for a 20 mm rod under normal axial loads, but if your application introduces significant side forces, consider adding an external linear guide or switching to a guided cylinder to protect the rod and bearing.
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 SCJ63 Standard Cylinder SCJ63X100-30H FAQ
At 0.5 MPa, the push force is 1559 N and the pull force is 1402 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 2805 N. Because it is a single-rod cylinder, the push force is always greater than the pull force due to the rod area on the return side.
Yes, if you need the added benefit of a field-adjustable stroke end. The SCJ63X100-30H shares the same mounting footprint and port size as a standard SC63. Ensure you match the 100 mm nominal stroke, 30 mm adjustment range, PT threads, and Viton seals for a direct functional replacement.
