Airtac SCJ32 Standard Cylinder SCJ32X400-10S
The AirTAC Airtac SCJ32 Standard Cylinder SCJ32X400-10S is a genuine double-acting SINGLE-ROD air cylinder with a rear-cap ADJUSTING SCREW: the stroke end is field-adjustable within a 10 mm range without swapping the cylinder. Ø32mm bore, 400mm nominal stroke, PT1/8 ports and adjustable end cushioning.

About the Airtac SCJ32 Standard Cylinder SCJ32X400-10S
The SCJ32X400-10S puts a 10 mm field-adjustable stroke end into a compact 32 mm bore tie-rod body, delivering 402 N of push force at a standard 0.5 MPa supply. Its rear-cap adjusting screw lets you fine-tune the end position without removing the cylinder or adding external hard stops, which is especially useful during commissioning runs and small-bore pick-and-place setups.
A built-in magnet (the -S suffix) allows CMSG, DMSG or EMSG sensors to clamp directly onto the 182 mm body, giving clean end-of-stroke or mid-position signals. The 12 mm rod runs in a 21 mm air cushion, and the PT1/8 port keeps the footprint small. At 0.9 MPa the push force reaches 724 N, while the pull force is 345 N at 0.5 MPa due to the single-rod design.
Airtac SCJ32 Standard Cylinder SCJ32X400-10S Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X400-10S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 400 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 SCJ32X400-10S Is Used
Commissioning Fine-Tuning
The 10 mm screw adjustment lets technicians dial in the exact stroke end during machine setup without swapping cylinders, saving hours on multi-station small-part assembly lines.
Pick-and-Place End-Stop
Adjust the retract position to compensate for gripper finger wear or part tolerance drift in electronics assembly, keeping placement accuracy tight over thousands of cycles.
Small-Part Diverter Gate
Fine-tune the gate opening stroke on a packaging conveyor to handle different product widths, using the magnet sensor to confirm the gate is fully open before releasing the next item.
Is the Airtac SCJ32 Standard Cylinder SCJ32X400-10S the Right Cylinder?
Step up to the 40 mm bore if your load consistently exceeds the 402 N push at 0.5 MPa—the SCJ40 delivers 628 N push at the same pressure. For fixed-stroke applications where no end adjustment is needed, the standard SC32 is a simpler, lower-cost alternative. A direct replacement must match the 32 mm bore, 400 mm nominal stroke, 10 mm adjust range, PT thread, and the -S magnet; the basic mount style means no additional bracket is included. At 400 mm of stroke, consider an external guide rail or a guided cylinder if the rod sees any side load, as the 12 mm rod can buckle under off-axis forces.
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 SCJ32X400-10S FAQ
Push force is 402 N at 0.5 MPa, 563 N at 0.7 MPa, and 724 N at the maximum operating pressure of 0.9 MPa. Pull force is lower—345 N at 0.5 MPa—because the 12 mm rod reduces the piston area on the return stroke.
Yes, if you need the 10 mm stroke-end adjustment. The SCJ32 shares the same bore, rod, port, and mounting accessories as the SC32, but the body length A is 182 mm—slightly longer to house the adjusting screw. Ensure the extra length fits your machine envelope.
