About the Airtac SCJ100 Standard Cylinder SCJ100X500-10
The SCJ100X500-10 is a double-acting, single-rod pneumatic cylinder with a field-adjustable stroke, delivering a substantial 3927 N of push force at 0.5 MPa. Its rear-cap adjusting screw provides a 10 mm range to precisely shorten the stroke end, allowing engineers to fine-tune the piston's stopping position without replacing the cylinder or adding external hard stops. The 100 mm bore uses a 25 mm diameter piston rod and PT1/2 ports.
This tie-rod cylinder is designed for applications requiring high force and on-machine adjustability. The 500 mm nominal stroke is within the standard offering for this bore, and the body length A(SCJ) is 245 mm. The adjustable air cushion decelerates the piston smoothly at the end of travel, protecting the end cap from impact. For position sensing, a magnet can be added by ordering the -S suffix variant.
Airtac SCJ100 Standard Cylinder SCJ100X500-10 Technical Specifications
| Model | Airtac SCJ100 Standard Cylinder SCJ100X500-10 |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø100 mm |
| Nominal stroke | 500 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 SCJ100X500-10 Is Used
End-Stop Calibration
The 10 mm adjusting screw allows operators to compensate for tooling wear or minor machine frame shifts over time, maintaining precise part positioning without disassembling the actuator.
Product Format Changeover
Quickly adapt a pusher or diverter station for different box sizes on a packaging line. The adjustable stroke eliminates the need to swap cylinders or mechanical stops between production runs.
Clamping with Variable Thickness
Fine-tune the final clamp position for workpieces with slight thickness variations in a machining fixture. The screw adjustment provides a simple, repeatable mechanical setting for the 3927 N clamping force.
Is the Airtac SCJ100 Standard Cylinder SCJ100X500-10 the Right Cylinder?
Select the SCJ100X500-10 when you need to dial in a precise end position on a 500 mm stroke during commissioning or format changeovers. If the 3927 N push force at 0.5 MPa is more than required, stepping down to an SCJ80 bore provides 2513 N of push force. For applications demanding a fixed, non-adjustable stroke, the standard SC100X500 is a direct alternative. A direct replacement must match the 100 mm bore, 500 mm nominal stroke, 10 mm adjust range, PT port thread, and basic mounting style.
For a 500 mm stroke, be mindful of side-loading on the 25 mm rod. If the load is not guided externally, the bending moment can cause premature rod bearing and seal wear. In such cases, couple the cylinder with an external guide rail or consider a guided cylinder assembly to absorb transverse forces.
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 SCJ100X500-10 FAQ
At the standard 0.5 MPa operating pressure, the cylinder generates 3927 N of push force and 3681 N of pull force. The push force is higher because the pressure acts on the full 100 mm bore area, while the pull force subtracts the 25 mm rod area. The maximum push force at 0.9 MPa is 7068 N.
Yes, the SCJ100X500-10 has the same mounting footprint and port size as a fixed-stroke SC100X500. The key difference is the rear adjusting screw, which makes the overall body length slightly longer. Ensure you have clearance for the screw mechanism and that the 10 mm adjustment range is sufficient for your application.
