About the Airtac SCJ100 Standard Cylinder SCJ100X500-100
The SCJ100X500-100 is a double-acting, single-rod pneumatic cylinder that integrates a rear-cap adjusting screw, giving you up to 100 mm of field-adjustable stroke-end reduction without replacing the unit. With a 100 mm bore, it delivers 3927 N of push force at 0.5 MPa and 7068 N at 0.9 MPa, using a 25 mm diameter piston rod and PT1/2 ports.
This adjustable-stroke design is ideal for commissioning trials, format changeovers, or wear take-up on long-stroke tooling. The body length A(SCJ) is 245 mm, and the cylinder includes an adjustable air cushion with a 29 mm cushion length to decelerate the piston smoothly. It is a genuine AirTAC tie-rod cylinder, not an ISO 15552 profile type.
Airtac SCJ100 Standard Cylinder SCJ100X500-100 Technical Specifications
| Model | Airtac SCJ100 Standard Cylinder SCJ100X500-100 |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø100 mm |
| Nominal stroke | 500 mm |
| Stroke adjustment | Up to 100 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 SCJ100X500-100 Is Used
Commissioning & Setup
Fine-tune the end-of-stroke position during initial machine setup without swapping cylinders or machining hard stops, saving hours of integration time.
Product Format Changeover
Quickly adjust the stroke end for different product sizes on packaging or sorting lines, enabling rapid changeover between batches with a simple screw turn.
Wear Compensation
Compensate for mechanical wear in tooling or gripper pads over time by incrementally adjusting the stroke end, maintaining precise contact without replacing the actuator.
Is the Airtac SCJ100 Standard Cylinder SCJ100X500-100 the Right Cylinder?
Choose the SCJ100X500-100 when you need to fine-tune the stroke end position on a machine with a 500 mm nominal reach. If your force requirement is lower, stepping down to an 80 mm bore provides 2513 N of push force at 0.5 MPa. For applications needing a fixed, non-adjustable stroke, the standard SC100X500 is a simpler alternative. This model replaces any AirTAC SCJ100 cylinder with the same 500 mm nominal stroke, 100 mm adjust range, PT ports, and basic mounting.
For a 500 mm stroke, ensure the rod is not subjected to high side loads. If lateral forces are present, pair the cylinder with an external linear guide or consider a guided cylinder to prevent rod bending and premature seal wear.
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 SCJ100 Standard Cylinder SCJ100X500-100 FAQ
At 0.5 MPa, the push force is 3927 N and the pull force is 3681 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 7068 N. The pull force is lower because the 25 mm rod reduces the effective piston area on the return stroke.
Yes, if you need the ability to adjust the stroke end. The SCJ100X500-100 mounts identically to an SC100 and uses the same PT1/2 ports. Ensure your application can accommodate the slightly longer body length A(SCJ) of 245 mm due to the rear adjusting screw mechanism.
