About the Airtac SCJ32 Standard Cylinder SCJ32X400-100S
The SCJ32X400-100S is a double-acting, single-rod tie-rod cylinder that lets you dial in the stroke end position with a rear adjusting screw, offering a full 100 mm of field-adjustable range. With a 12 mm rod and PT1/8 ports, it delivers 402 N of push force at 0.5 MPa, making it a precise actuator for light automation tasks where the stroke must be tuned during commissioning or changeover.
This model includes a built-in magnet (-S suffix), so CMSG, DMSG, or EMSG sensors clamp directly onto the barrel for non-contact position sensing. The standard TPU seal operates from -20 to +70 °C, and the 21 mm air cushion at each end decelerates the piston quietly. The body length A dimension is 182 mm, giving a compact footprint for its 400 mm nominal stroke.
Airtac SCJ32 Standard Cylinder SCJ32X400-100S Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X400-100S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 400 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 SCJ32X400-100S Is Used
Commissioning & Setup
Fine-tune the end-of-stroke position during machine bring-up without swapping cylinders or machining hard stops, saving hours of mechanical adjustment.
Small-Part Diverter Gates
Adjust the gate opening stroke on a packaging line to handle different product sizes, using the 100 mm range to quickly adapt between formats.
Sensor-Guided Positioning
Pair the built-in magnet with CMSG sensors to confirm the piston has reached the adjusted end stop, providing closed-loop feedback for quality checks.
Is the Airtac SCJ32 Standard Cylinder SCJ32X400-100S the Right Cylinder?
Choose the SCJ32 when you need a compact, adjustable-stroke cylinder in the 402 N push class. If your load requires more force, step up to the SCJ40, which provides 628 N push at the same 0.5 MPa pressure. For applications where the stroke never needs field adjustment, the fixed-stroke SC32 is a simpler, cost-effective alternative. When replacing an existing SCJ32X400-100S, match the bore, 400 mm nominal stroke, 100 mm adjust range, PT port thread, and the built-in magnet; the basic mounting style uses no additional bracket. For strokes of 300 mm or more, consider an external guide rail or a guided cylinder if the rod is exposed to side loads, as the 12 mm rod can deflect under off-axis forces.
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 SCJ32X400-100S FAQ
At 0.5 MPa, it generates 402 N pushing and 345 N pulling (the difference is due to the single rod). At the maximum operating pressure of 1.0 MPa, the theoretical push force is 804 N.
Yes, if you need field-adjustable stroke. The SCJ32 shares the same bore, rod, and port dimensions as the SC32, but adds a rear adjusting screw. Ensure your mounting and sensor setup accommodates the slightly longer SCJ body length (A = 182 mm).
