About the Airtac SCJ32 Standard Cylinder SCJ32X250-10
The SCJ32X250-10 is a double-acting, single-rod tie-rod cylinder with a rear adjusting screw that lets you dial the stroke end back by up to 10 mm. With a 12 mm rod and PT1/8 ports, it delivers 402 N of push force at 0.5 MPa (724 N at 0.9 MPa), making it a capable mid-stroke actuator for light positioning tasks.
The 21 mm air cushion decelerates the piston smoothly, and the 182 mm body length keeps the envelope compact. This model ships with a TPU seal, PT threads, and no magnet, suiting standard-temperature applications where you need to commission a precise end position without swapping cylinders.
Airtac SCJ32 Standard Cylinder SCJ32X250-10 Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X250-10 |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 250 mm |
| Stroke adjustment | Up to 10 mm (rear adjusting screw) |
| Acting type | Double acting (single rod) |
| Port size | PT1/8 |
| Rod thread | M10×1.25 |
| 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, 21 mm |
| Max stroke | Up to 1000 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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 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 SCJ32 Standard Cylinder SCJ32X250-10 Is Used
Commissioning & Setup
Trim the end stop by up to 10 mm during machine commissioning without removing the cylinder, speeding up line start-up.
Wear Compensation
Adjust the stroke end to take up mechanical wear in gripper jaws or clamping fixtures over time, maintaining consistent part contact.
Small-Part Sorting
Fine-tune the push-off position on a sorting conveyor to handle different product widths without reprogramming the controller.
Is the Airtac SCJ32 Standard Cylinder SCJ32X250-10 the Right Cylinder?
Choose the SCJ32X250-10 when your process needs a 250 mm nominal stroke with the ability to trim the end point by a few millimetres during setup or changeover. If you need more push force, the 40 mm bore SCJ delivers 628 N at 0.5 MPa; if space is tight and force is less critical, the 32 mm bore is the right pick. For a fixed, non-adjustable stroke, the standard SC series is a simpler alternative.
For a direct replacement, match the 32 mm bore, 250 mm nominal stroke, 10 mm adjust range, PT port thread, and basic mounting. If your application involves side loads, consider adding an external guide rail or switching to a guided cylinder, as the 12 mm rod is not designed to bear lateral forces.
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 SCJ32 Standard Cylinder SCJ32X250-10 FAQ
At 0.5 MPa, the push force is 402 N and the pull force is 345 N (the pull force is lower because the 12 mm rod reduces the piston area on the return side). At the maximum operating pressure of 0.9 MPa, push force reaches 724 N.
Yes, if the bore (32 mm), nominal stroke (250 mm), port thread (PT1/8), and mounting style match. The SCJ body is slightly longer to house the adjusting screw, so check your machine envelope. The adjusting screw lets you fine-tune the stroke end, which a fixed-stroke SC cannot do.
