About the Airtac SCJ32 Standard Cylinder SCJ32X225-10
The SCJ32X225-10 is a 32mm bore double-acting single-rod cylinder with a field-adjustable stroke end, giving you up to 10mm of fine-tuning range via the rear-cap screw. Its 12mm diameter piston rod delivers 402N of push force and 345N of pull force at 0.5MPa, making it a compact yet capable actuator for light positioning and gauging tasks.
This model has a nominal 225mm stroke, well within the 1000mm maximum standard stroke for the 32mm bore, and includes an adjustable air cushion (21mm length) for smooth deceleration. The body length A(SCJ) is 182mm, and the port is PT1/8 with an M10x1.25 rod thread, supplied here in the basic configuration with TPU seals and PT threads.
Airtac SCJ32 Standard Cylinder SCJ32X225-10 Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X225-10 |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 225 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 SCJ32X225-10 Is Used
Commissioning Fine-Tuning
During machine setup, the 10mm adjustment screw lets technicians dial in the exact stop position for a sensor or nest without re-machining mounting brackets.
Wear Compensation
In light pressing or clamping fixtures, the adjustable stroke end can be advanced slightly to compensate for pad wear, maintaining consistent contact force over time.
Part-Present Confirmation
Used as a retractable stop in a conveyor gate, the stroke can be fine-tuned to accommodate slight variations in part width from different batches.
Is the Airtac SCJ32 Standard Cylinder SCJ32X225-10 the Right Cylinder?
Choose the SCJ32X225-10 when your application needs a stroke that can be dialed in precisely on the machine without swapping the cylinder. If you require more force, stepping up to the 40mm bore provides 628N of push at 0.5MPa. For applications where the stroke is fixed and never needs adjustment, the standard SC32X225 fixed-stroke cylinder is a simpler, cost-effective alternative. A direct replacement must match the 32mm bore, 225mm nominal stroke, 10mm adjust range, PT1/8 ports, and basic mounting.
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 SCJ32X225-10 FAQ
At the standard operating pressure of 0.5MPa, this 32mm bore cylinder generates 402N of push force and 345N of pull force. The maximum push force at 0.9MPa is 724N, with a theoretical maximum of 82kgf at 1.0MPa.
You can, provided the 10mm rear adjustment screw does not interfere with your mounting. The SCJ body is slightly longer than the fixed-stroke SC. Ensure the 225mm nominal stroke, PT1/8 ports, and M10x1.25 rod thread match your existing setup.
