About the Airtac SCJ32 Standard Cylinder SCJ32X225-100S
The SCJ32X225-100S is a double-acting, single-rod pneumatic cylinder with a rear adjusting screw that lets you fine-tune the stroke end by up to 100 mm without removing the unit. With a 32 mm bore and 12 mm rod, it delivers 402 N of push force at 0.5 MPa, making it a compact but capable actuator for light industrial tasks.
This model includes a built-in magnet (-S suffix) so CMSG/DMSG sensors can mount directly on the tie-rod barrel for reliable end-of-stroke detection. The body length A(SCJ) is 182 mm for the base cylinder, and the adjustable cushion helps decelerate the 225 mm nominal stroke smoothly. Operating pressure ranges from 0.15 to 1.0 MPa with filtered air.
Airtac SCJ32 Standard Cylinder SCJ32X225-100S Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X225-100S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 225 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 SCJ32X225-100S Is Used
Commissioning & Setup
The 100 mm rear screw adjustment lets technicians dial in the exact stroke end on a new machine during runoff, eliminating the need to swap cylinders or fabricate custom stops.
Small Part Stops & Gates
Used as an adjustable end-stop on a conveyor line, the 32 mm bore provides enough force to position lightweight products, and the stroke can be fine-tuned for different package sizes.
Wear Take-Up in Clamping
In a repetitive clamping fixture, the adjustable stroke compensates for pad wear over time, maintaining consistent clamping force without reprogramming the PLC or adding shims.
Is the Airtac SCJ32 Standard Cylinder SCJ32X225-100S the Right Cylinder?
Choose this 32 mm bore SCJ when you need a field-adjustable stroke up to 225 mm and around 402 N of push force at standard plant air. If your load demands more force, step up to the 40 mm bore (628 N push at 0.5 MPa); for a lighter, more compact footprint, the 32 mm is the smallest SCJ option. The 100 mm adjustment range is ideal for commissioning trials where the exact stop position must be dialled in on the machine.
For replacement, match an AirTAC SCJ32 cylinder with the same 225 mm nominal stroke, 100 mm adjust range, PT port thread, and built-in magnet. If the stroke is fixed after setup, a standard SC32 fixed-stroke cylinder may be a simpler alternative. At this stroke length, ensure the rod is not subjected to high side loads; use an external guide rail if the load is not perfectly axial.
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 SCJ32X225-100S FAQ
At 0.5 MPa, it delivers 402 N pushing force and 345 N pulling force. The maximum push force at the 0.9 MPa operating limit is 724 N. Always size for the lower pulling force if the cylinder works in both directions.
Yes, if you need the adjustable stroke feature. The SCJ32 shares the same bore, rod, and port dimensions as the SC32 but adds a rear adjusting screw. Ensure the longer body length A(SCJ) of 182 mm fits your mounting space and that you match the magnet option (-S) if you use sensors.
