About the Airtac SCJ100 Standard Cylinder SCJ100X80-100
The SCJ100X80-100 is a double-acting, single-rod pneumatic cylinder with a field-adjustable stroke end, providing a generous 100 mm of adjustment range via the rear-cap screw. With a 100 mm bore, it delivers a substantial 3927 N of push force at 0.5 MPa and up to 7068 N at the maximum operating pressure of 0.9 MPa, making it suitable for heavy-duty positioning tasks where the end-stop needs frequent, precise tuning.
This model features a 25 mm diameter piston rod, PT1/2 ports, and an M20x1.5 rod thread for robust connection. The adjustable cushion is 29 mm long, and the body length A(SCJ) is 245 mm. The 80 mm nominal stroke is the maximum travel, which can be shortened by up to 100 mm without dismounting the cylinder, ideal for commissioning and format changeovers on large machinery.
Airtac SCJ100 Standard Cylinder SCJ100X80-100 Technical Specifications

|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø100 mm |
| Nominal stroke | 80 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 SCJ100X80-100 Is Used
Commissioning & Setup
During machine commissioning, the 100 mm adjustment screw allows engineers to dial in the exact end-stop position for a 100 mm bore actuator without swapping hard stops or cylinder models, saving hours of mechanical rework.
Product Format Changeover
On packaging lines handling different box sizes, the SCJ100X80-100 can quickly adapt its stroke end to match a new product dimension. The operator simply adjusts the rear screw, eliminating the need for multiple fixed-stroke cylinders.
Wear Compensation
In high-cycle pressing or clamping operations, tooling surfaces wear over time. This adjustable-stroke cylinder lets maintenance staff advance the stroke end to compensate for wear, maintaining consistent clamp force and part quality without replacing the actuator.
Is the Airtac SCJ100 Standard Cylinder SCJ100X80-100 the Right Cylinder?
Choose the SCJ100X80-100 when you need to fine-tune the stroke end position within a 100 mm window on a 100 mm bore platform. If your force requirement is lower, stepping down to an 80 mm bore (2513 N push at 0.5 MPa) can reduce air consumption and physical size. For applications needing a fixed, non-adjustable stroke, the standard SC100 series is a more economical choice. This cylinder is a direct replacement for another AirTAC SCJ100 cylinder with an 80 mm nominal stroke and a 100 mm adjustment range, matching PT port threads and basic mounting. For strokes of 300 mm or more, always consider an external guide rail or a guided cylinder to protect the 25 mm rod from side-load deflection.
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 SCJ100X80-100 FAQ
At 0.5 MPa, the push force is 3927 N and the pull force is 3681 N. The pull force is lower due to the area of the 25 mm piston rod. At the maximum operating pressure of 0.9 MPa, the push force reaches 7068 N.
A rear-cap adjusting screw lets you shorten the stroke end by up to 100 mm from the 80 mm nominal maximum. Choose this SCJ model when your application requires fine-tuning the end position during setup, for different product runs, or to compensate for wear. A fixed-stroke SC cylinder is a simpler, lower-cost option if the stroke length never needs field adjustment.
