About the Airtac SCJ32 Standard Cylinder SCJ32X250-100S
The SCJ32X250-100S is a 32 mm bore double-acting single-rod cylinder that gives you a full 100 mm of field-adjustable stroke-end travel via the rear-cap screw. At 0.5 MPa it delivers 402 N push and 345 N pull, letting you dial in the exact end position for commissioning or format changes without swapping the cylinder.
This model includes a built-in magnet (-S) so CMSG/DMSG/EMSG sensors clamp directly onto the tie-rod barrel for end-of-stroke detection. The 12 mm rod runs in a PT1/8 ported body with a 21 mm air cushion and a body length A of 182 mm, making it a compact choice for light automation tasks needing frequent stroke tweaks.
Airtac SCJ32 Standard Cylinder SCJ32X250-100S Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X250-100S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 250 mm |
| Stroke adjustment | Up to 100 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 SCJ32X250-100S Is Used
Commissioning Fine-Tuning
Adjust the stroke end by up to 100 mm on the machine during initial setup to perfectly align the actuator with mating parts without re-machining brackets.
Small-Part Diverter Gates
The 402 N push force is ideal for lightweight diverter flaps on conveyors, where the adjustable screw lets you fine-tune the gate opening for different product sizes.
Wear Compensation in Clamping
In repetitive clamping fixtures, use the 100 mm adjuster to take up mechanical wear on contact surfaces over time, maintaining consistent clamp force without reprogramming.
Is the Airtac SCJ32 Standard Cylinder SCJ32X250-100S the Right Cylinder?
Choose this 32 mm bore when your push force requirement is around 400 N at 0.5 MPa. If you need more force, stepping up to the 40 mm bore provides 628 N push. For applications where the stroke never changes, the fixed-stroke SC32X250 is a simpler alternative. This adjustable-stroke unit is a direct replacement for an existing AirTAC SCJ32X250-100S with a PT port and magnet.
At a 250 mm nominal stroke, ensure the rod is not subjected to high side loads. If lateral forces are present, add an external linear guide or consider a guided cylinder to prevent rod bending and premature seal wear.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-100)
- ✓ 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 SCJ32X250-100S FAQ
At 0.5 MPa, it generates 402 N of push force and 345 N of pull force. The maximum push force at 0.9 MPa is 724 N. Because it is a single-rod cylinder, the push force is greater than the pull force due to the rod area on the return side.
Yes, if you need the ability to adjust the stroke end. The SCJ32X250-100S has the same 32 mm bore and 250 mm maximum stroke, but adds a rear adjusting screw that can shorten the stroke by up to 100 mm. Ensure your mounting and porting (PT1/8) match.
