About the Airtac SCJ32 Standard Cylinder SCJ32X250-10S
The SCJ32X250-10S is a 32 mm bore double-acting, single-rod cylinder that provides 402 N of push force at 0.5 MPa. Its rear-cap adjusting screw allows the stroke end to be shortened by up to 10 mm, making it ideal for commissioning fine-tuning or taking up mechanical wear without replacing the cylinder.
This model includes a built-in magnet (-S suffix), enabling direct mounting of CMSG/DMSG/EMSG sensors on the tie-rod barrel for reliable end-of-stroke detection. The 12 mm diameter piston rod and PT1/8 port ensure a compact pneumatic solution for light automation tasks.
Airtac SCJ32 Standard Cylinder SCJ32X250-10S Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X250-10S |
|---|---|
| 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 SCJ32X250-10S Is Used
Commissioning Fine-Tuning
The 10 mm rear adjuster lets technicians dial in the exact stroke end during machine setup, compensating for minor assembly tolerances without needing to re-machine brackets or swap cylinders.
Wear Take-Up on Stops
In repetitive stopping applications, the adjustable screw can be periodically advanced to compensate for wear on external hard stops, maintaining precise positioning over the cylinder's service life.
Sensor-Ready Light Automation
With the built-in magnet, this cylinder is ready for CMSG/DMSG sensors, providing clean electrical signals for cycle counting and sequence control in small pick-and-place or sorting mechanisms.
Is the Airtac SCJ32 Standard Cylinder SCJ32X250-10S the Right Cylinder?
Choose the SCJ32X250-10S when you need field-adjustable stroke end positioning in a light-duty application. If your force requirement increases, stepping up to the 40 mm bore provides 628 N of push force at the same pressure. For applications where the stroke is fixed and never needs field adjustment, the standard SC series offers a simpler, cost-effective alternative.
This cylinder is a direct replacement for any AirTAC SCJ32X250-10S with a PT port and basic mounting. For strokes of 250 mm, ensure the rod is not subjected to high side loads; if lateral forces are present, use an external linear guide 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 SCJ32 Standard Cylinder SCJ32X250-10S FAQ
At 0.5 MPa, the push force is 402 N and the pull force is 345 N. The maximum operating force at 0.9 MPa is 724 N of push. The pull force is lower because the 12 mm piston rod reduces the effective area on the return stroke.
Yes, provided the bore, port thread, and mounting match. The SCJ body length A is 182 mm, which is slightly longer than a fixed-stroke SC of the same bore to accommodate the rear adjusting mechanism. The adjustable stroke adds the ability to fine-tune the end position by up to 10 mm.
