About the Airtac SCJ32 Standard Cylinder SCJ32X30-10
The SCJ32X30-10 is a compact double-acting single-rod cylinder that puts stroke-end fine-tuning directly on the machine. With a 32 mm bore, 12 mm piston rod, and a rear adjusting screw that provides up to 10 mm of stroke shortening, it delivers 402 N of push force at 0.5 MPa—ideal for light clamping, sorting gates, and small-part positioning where the final stop point needs to be dialled in during commissioning.
Its tie-rod construction keeps the body length A at 182 mm, and the PT1/8 port with M10x1.25 rod thread simplifies plumbing and tooling attachment. The 21 mm air cushion at each end decelerates the piston smoothly, while the screw sets the exact stroke end without changing the cylinder itself.
Airtac SCJ32 Standard Cylinder SCJ32X30-10 Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X30-10 |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 30 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 SCJ32X30-10 Is Used
Commissioning & Setup
Dial in the exact end-stop position for a sensor bracket or ejector blade during machine build, using the 10 mm rear screw adjustment without swapping shims or hard stops.
Small-Part Sorting Gate
Adjust the gate opening stroke on a conveyor diverter to handle different component heights, fine-tuning the 30 mm nominal stroke down by up to 10 mm for a precise pass gap.
Wear Take-Up on Clamps
Compensate for jaw or pad wear on a light-duty clamping fixture by shortening the stroke end slightly, maintaining consistent clamping force without replacing the cylinder.
Is the Airtac SCJ32 Standard Cylinder SCJ32X30-10 the Right Cylinder?
Step up to the 40 mm bore SCJ (628 N push at 0.5 MPa) if the 32 mm frame runs near its force limit, or downsize if space is tighter and the load is under 345 N pull. When the stroke length is fixed and never needs field adjustment, the standard SC series saves cost and lead time. For a direct replacement, match the 32 mm bore, 30 mm nominal stroke, 10 mm adjust range, PT thread, and basic mounting. For strokes of 300 mm or more, consider an external guide rail or a guided cylinder to protect the 12 mm rod from side loads and bending.
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 SCJ32X30-10 FAQ
At 0.5 MPa, the cylinder delivers 402 N pushing and 345 N pulling. The push force is higher because the single rod reduces the piston area on the pull side. At the maximum operating pressure of 0.9 MPa, push force reaches 724 N.
Yes, if you need the ability to fine-tune the stroke end. Match the 32 mm bore, 30 mm nominal stroke, PT1/8 port, and basic mounting. The SCJ body is slightly longer due to the rear adjusting screw, so check the 182 mm A-length against your available space.
