About the Airtac SCJ63 Standard Cylinder SCJ63X100-100SH
The SCJ63X100-100SH is a double-acting, single-rod pneumatic cylinder with a 100 mm nominal stroke, featuring a rear adjusting screw that provides a full 100 mm of field-adjustable stroke shortening. This allows precise end-position tuning without swapping the cylinder, ideal for applications requiring frequent format changes or fine mechanical setup. It delivers a push force of 1559 N at 0.5 MPa and up to 2805 N at the maximum operating pressure of 0.9 MPa, using a 20 mm diameter piston rod.
This model is configured with a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, and high-temperature Viton (FKM) seals (-H), extending the operating temperature range from the standard -20 to +70°C up to 0 to +150°C. The 63 mm bore body has a length A of 197 mm and features a PT1/4 port with an M16x1.5 rod thread, making it a robust choice for hot or demanding environments where sensor feedback is critical.
Airtac SCJ63 Standard Cylinder SCJ63X100-100SH Technical Specifications
| Model | Airtac SCJ63 Standard Cylinder SCJ63X100-100SH |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø63 mm |
| Nominal stroke | 100 mm |
| Stroke adjustment | Up to 100 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 SCJ63X100-100SH Is Used
High-Temp Format Changeover
In heated packaging or laminating machinery, the 100 mm adjustment range allows operators to quickly dial in a new product size without mechanical disassembly, while the Viton seals handle the sustained heat.
Foundry & Mold Actuation
Fine-tunes the end-stop for a core pull or ejector mechanism in a hot mold environment. The 100 mm screw range compensates for thermal expansion differences during commissioning.
Sensor-Monitored Pressing
Combines the built-in magnet for end-of-stroke sensing with a 2805 N pressing force at 0.9 MPa, enabling precise, adjustable-depth clamping or insertion cycles in automated assembly.
Is the Airtac SCJ63 Standard Cylinder SCJ63X100-100SH the Right Cylinder?
Choose this SCJ63 variant when you need a 100 mm nominal stroke that can be reduced by up to 100 mm on the machine, paired with high-temperature capability. If the 1559 N push force at 0.5 MPa is insufficient, stepping up to the 80 mm bore provides 2513 N; if it is excessive, the 50 mm bore offers 982 N. For applications where the stroke does not require field adjustment, a fixed-stroke SC63 cylinder is a simpler alternative. This is a direct replacement for an AirTAC SCJ63X100-100SH with PT ports, basic mount, magnet, and Viton seals. For strokes of 100 mm, rod bending from side loads is typically not a primary concern, but always ensure loads are guided if any lateral force is present.
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 SCJ63 Standard Cylinder SCJ63X100-100SH 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. The pull force is lower due to the area of the 20 mm piston rod.
The -100 suffix indicates the rear adjusting screw can shorten the stroke end by up to 100 mm. The cylinder's nominal maximum stroke is 100 mm, so the effective stroke is field-adjustable from 0 to 100 mm. It does not change the cylinder's force or speed.
