About the Airtac SCJ32 Standard Cylinder SCJ32X250-100
The SCJ32X250-100 is a double-acting, single-rod pneumatic cylinder that puts fine stroke control directly on the machine. Its rear-cap adjusting screw lets you shorten the stroke end by up to 100 mm, so the effective stroke can be field-tuned anywhere from 150 mm to the full 250 mm nominal length. This 32 mm bore unit delivers 402 N of push force at 0.5 MPa and 724 N at the maximum operating pressure of 0.9 MPa, using a 12 mm diameter piston rod.
Built on the rugged SC tie-rod platform, this cylinder includes an adjustable air cushion (21 mm long) for smooth deceleration and operates on standard filtered air from 0.15 to 1.0 MPa. The body length A is 182 mm plus stroke, making it a compact solution for applications where you need to dial in the end position during commissioning or after tooling wear, without swapping the cylinder or adding external hard stops.
Airtac SCJ32 Standard Cylinder SCJ32X250-100 Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X250-100 |
|---|---|
| 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 SCJ32X250-100 Is Used
Commissioning & Setup
Dial in the exact stroke end position during machine commissioning without cutting rods or machining custom stops. The 100 mm adjustment range allows rapid fine-tuning on the factory floor.
Wear Compensation
In clamping or pressing fixtures, use the rear screw to take up mechanical wear on tooling or contact surfaces over time, maintaining consistent clamping force without reprogramming.
Small-Part Sorting Gates
Adjust the gate opening stroke on a sorting conveyor to handle different product sizes. The 32 mm bore provides ample force for lightweight diverters while the screw sets the precise opening limit.
Is the Airtac SCJ32 Standard Cylinder SCJ32X250-100 the Right Cylinder?
Choose the SCJ32 when you need a compact, adjustable end-stop within a 100 mm window. If your force requirements grow, stepping up to the SCJ40 provides 628 N of push at 0.5 MPa. For applications where the stroke is fixed and never needs field adjustment, the simpler SC32 fixed-stroke cylinder is a more economical choice. This model is a direct replacement for an existing AirTAC SCJ32X250-100 with PT ports and basic mounting; ensure the adjust range and port thread match exactly. For strokes of 250 mm, ensure the rod is guided if significant side loads are present, or consider a guided cylinder to prevent rod bending and 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 SCJ32X250-100 FAQ
At the standard 0.5 MPa operating pressure, the push force is 402 N and the pull force is 345 N (lower due to the 12 mm rod area). At the maximum operating pressure of 0.9 MPa, the push force reaches 724 N. Always use the pull force value when sizing the return stroke.
Only if you need the adjustable stroke feature. The SCJ32X250-100 has a longer body to house the rear adjusting mechanism and will not fit in the exact same envelope as a fixed-stroke SC32. It is a direct dimensional match only for another AirTAC SCJ32X250-100 with the same adjust range, port thread, and mounting type.
