About the Airtac SCJ100 Standard Cylinder SCJ100X230-20TC
The SCJ100X230-20TC is a double-acting, single-rod pneumatic cylinder with a field-adjustable stroke end, letting you fine-tune the piston stop position by up to 20 mm without removing the unit. With a 100 mm bore, it delivers a substantial 3927 N of push force at just 0.5 MPa, making it a workhorse for pressing, clamping, and positioning tasks that need on-machine tweaking.
This model is configured with a centre trunnion (TC) mount, which allows the cylinder to pivot and is ideal for swinging or articulating loads. It uses a 25 mm diameter piston rod, PT1/2 ports, and an adjustable air cushion to decelerate the 230 mm stroke smoothly. The body length A(SCJ) is 245 mm, providing a compact footprint for its force class.
Airtac SCJ100 Standard Cylinder SCJ100X230-20TC Technical Specifications
| Model | Airtac SCJ100 Standard Cylinder SCJ100X230-20TC |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø100 mm |
| Nominal stroke | 230 mm |
| Stroke adjustment | Up to 20 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 SCJ100X230-20TC Is Used
Format Changeovers
Quickly adjust the end stop by up to 20 mm when switching between product sizes on a packaging or assembly machine, eliminating the need for mechanical shims or hard stops.
Part Ejection & Sorting
Fine-tune the push-off point for ejecting parts of varying thickness from a conveyor, ensuring consistent placement without reprogramming the PLC.
Clamping & Pressing
Dial in the exact clamping depth for a pneumatic press or welding fixture, compensating for electrode wear or material thickness variations on the fly.
Is the Airtac SCJ100 Standard Cylinder SCJ100X230-20TC the Right Cylinder?
Choose the SCJ100 when your application demands roughly 3900 N of push force at standard shop air. If you need a lighter, more compact actuator, the SCJ80 bore provides 2513 N of push at 0.5 MPa. For higher force requirements, step up to the SCJ125, which offers 6136 N at the same pressure. This adjustable-stroke model is the right pick when you anticipate needing to change the stroke end position during commissioning, format changeovers, or to compensate for tooling wear. If your stroke is fixed and will never need adjustment, the standard SC100 fixed-stroke cylinder is a simpler, more economical alternative. For a direct replacement, match the 100 mm bore, 230 mm nominal stroke, 20 mm adjustment range, PT port thread, and TC centre trunnion mounting (using the F-SC100TC kit). At this 230 mm stroke, ensure the rod is adequately supported against side loads; if significant lateral force is present, consider adding an external guide rail or switching to a guided cylinder assembly.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-20)
- ✓ 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 SCJ100X230-20TC FAQ
At 0.5 MPa, the push force is 3927 N and the pull force is 3681 N. At the maximum operating pressure of 1.0 MPa, the theoretical push force reaches 7068 N. The pull force is lower because the piston rod reduces the effective area on the return stroke.
A rear-cap adjusting screw lets you shorten the stroke end by up to 20 mm from the 230 mm maximum. It is a direct mechanical replacement for an SC100 fixed-stroke cylinder of the same bore and porting, provided you have clearance for the slightly longer SCJ body. You must also match the TC centre trunnion mount and PT thread to ensure drop-in compatibility.
