About the Airtac SCJ250 Standard Cylinder SCJ250X160-10
The SCJ250X160-10 is a heavy-duty, double-acting single-rod pneumatic cylinder with a rear-cap adjusting screw that provides a 10 mm field-adjustable stroke-end range. With a substantial 250 mm bore and a 50 mm piston rod, this tie-rod cylinder delivers a powerful push force of 24544 N at 0.5 MPa, making it suitable for large-scale clamping, pressing, and material handling applications where fine-tuning the end position is critical.
This ISO 6430 class cylinder features an adjustable air cushion (40 mm length) for smooth deceleration and operates on filtered air from 0.15 to 1.0 MPa. The body length A(SCJ) is 409 mm, and the standard port is PT1". The 10 mm adjustment screw allows operators to quickly compensate for tooling wear or slight variations in workpiece thickness without replacing the entire actuator.
Airtac SCJ250 Standard Cylinder SCJ250X160-10 Technical Specifications
| Model | Airtac SCJ250 Standard Cylinder SCJ250X160-10 |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder (ISO 6430 class) |
| Bore size | Ø250 mm |
| Nominal stroke | 160 mm |
| Stroke adjustment | Up to 10 mm (rear adjusting screw) |
| Acting type | Double acting (single rod) |
| Port size | PT1" |
| Rod thread | M42×2 |
| 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 – 500 mm/s |
| Cushion | Adjustable, 40 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 (Ø250mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 24544 N | 23562 N |
| 0.7 MPa | 34361 N | — |
| Max (@1.0 MPa) | 5006 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 SCJ250 Standard Cylinder SCJ250X160-10 Is Used
Heavy Press End-Stop Tuning
Fine-tune the final pressing depth on a hydraulic-style pneumatic press by adjusting the rear screw, ensuring consistent part dimensions across batches without reprogramming the machine.
Large Part Ejection Adjustment
Dial in the exact ejector stroke for large castings or molded parts on a conveyor line, compensating for mold wear or different part heights with a simple mechanical adjustment.
Commissioning Large Fixtures
Speed up the setup of large welding or assembly fixtures by using the 10 mm adjustment to find the optimal clamping position, then lock it in place for production runs.
Is the Airtac SCJ250 Standard Cylinder SCJ250X160-10 the Right Cylinder?
Select the SCJ250 bore when your application requires a push force around 24544 N at 0.5 MPa. If a lower force is sufficient, stepping down to the 200 mm bore provides 15708 N of push force, offering a more compact and cost-effective solution. This adjustable-stroke model is ideal when you need to dial in a precise mechanical stop during commissioning; for a fixed, repeatable stroke, the standard SC series is a simpler choice. For replacement, match the 250 mm bore, 160 mm nominal stroke, 10 mm adjust range, PT port thread, and basic mounting configuration. Given the 160 mm stroke, the rod is well-supported within the cylinder body, but for applications with significant side loads, an external guide rail or a guided cylinder is strongly recommended to prevent rod bending and premature seal wear.
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 SCJ250 Standard Cylinder SCJ250X160-10 FAQ
At the standard 0.5 MPa operating pressure, the push force is 24544 N and the pull force is 23562 N. The pull force is lower due to the area of the 50 mm piston rod. The maximum push force at the 0.9 MPa limit is 44178 N.
Yes, provided the bore, port thread (PT1"), and mounting match. The SCJ250X160-10 has the same envelope as an SC250X160 but includes a rear adjusting screw to shorten the stroke end by up to 10 mm. This adds a small amount to the overall body length compared to the fixed-stroke version.
