About the Airtac SCJ100 Standard Cylinder SCJ100X275-10
The SCJ100X275-10 is a double-acting, single-rod pneumatic cylinder that puts a 10 mm field-adjustable stroke end at your fingertips. With a 100 mm bore, it delivers 3927 N of push force at 0.5 MPa, scaling up to 7068 N at 0.9 MPa, making it a robust choice for heavy tooling that needs precise end-stop tuning without swapping the cylinder. The rear adjusting screw lets you fine-tune the stroke end during commissioning or format changes, all while the 25 mm piston rod and PT1/2 ports handle the flow.
This adjustable-stroke design uses a tie-rod construction with a body length of 245 mm. The integrated air cushion decelerates the piston smoothly, and the standard TPU seals work reliably from -20 to +70 °C. It is a genuine AirTAC SCJ unit, ready to simplify your machine setup by replacing fixed external stops with an internal, tamper-resistant adjustment.
Airtac SCJ100 Standard Cylinder SCJ100X275-10 Technical Specifications
| Model | Airtac SCJ100 Standard Cylinder SCJ100X275-10 |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø100 mm |
| Nominal stroke | 275 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 SCJ100X275-10 Is Used
End-Stop Commissioning
Fine-tune the retract stroke end by up to 10 mm during machine setup, eliminating the need to shim or reposition the entire cylinder when integrating new tooling.
Wear Compensation
On high-cycle material stops or clamps, the adjusting screw quickly takes up mechanical wear in the tooling, maintaining consistent part positioning without downtime for part changes.
Format Changeover
Adjust the stroke end in seconds when switching between product sizes on packaging or assembly machines, avoiding the cost and complexity of multiple fixed-stroke cylinders.
Is the Airtac SCJ100 Standard Cylinder SCJ100X275-10 the Right Cylinder?
Choose the SCJ100X275-10 when you need to dial in a 275 mm nominal stroke with up to 10 mm of end-position adjustment. If the 3927 N push force at 0.5 MPa is more than your application requires, stepping down to an 80 mm bore (2513 N push) can reduce air consumption and footprint. For applications demanding a fixed, non-adjustable stroke, the standard SC100X275 is a direct alternative. A direct replacement must match the 100 mm bore, 275 mm nominal stroke, 10 mm adjust range, PT port thread, and basic mounting. For this 275 mm stroke, ensure the rod is aligned axially with the load to prevent bending; if side loads are unavoidable, add an external guide rail or switch to a guided cylinder.
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 SCJ100X275-10 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, the SCJ100X275-10 can replace an SC100 of the same bore and nominal stroke if you need field adjustability. Ensure the port thread (PT) and mounting style match. The SCJ body is slightly longer to accommodate the rear adjusting mechanism, so verify your machine's space envelope.
