About the Airtac SCJ32 Standard Cylinder SCJ32X30-30
The SCJ32X30-30 is a 32 mm bore double-acting single-rod cylinder with a 30 mm nominal stroke and a 30 mm rear adjusting screw, letting you shorten the stroke end by up to 30 mm during commissioning or format changes. It delivers 402 N of push force at 0.5 MPa and 724 N at the maximum operating pressure of 0.9 MPa, with a 12 mm diameter piston rod and M10x1.25 rod thread.
This tie-rod cylinder uses PT1/8 ports and features an adjustable air cushion (21 mm long) for smooth deceleration. Its SCJ-specific body length A is 182 mm, making it compact enough for tight machine spaces where stroke fine-tuning is needed without replacing the actuator.
Airtac SCJ32 Standard Cylinder SCJ32X30-30 Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X30-30 |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 30 mm |
| Stroke adjustment | Up to 30 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 SCJ32X30-30 Is Used
Commissioning & Setup
Fine-tune the end position of a small clamp or stop during machine setup without re-plumbing or swapping cylinders. The 30 mm adjustment range covers most trial-and-error positioning needs on benchtop fixtures.
Wear Take-Up
Compensate for pad or gripper wear on light-duty assembly cells. Dial the stroke end forward by a few millimetres to restore precise contact, extending the life of consumable tooling.
Small Part Diverter
Adjust the push-off point of a diverter gate on a compact conveyor. The 30 mm screw range lets operators quickly match the stroke to different product widths without mechanical rework.
Is the Airtac SCJ32 Standard Cylinder SCJ32X30-30 the Right Cylinder?
Choose this 32 mm bore when push force around 402 N at 0.5 MPa is sufficient. If you need more force, step up to the 40 mm bore SCJ40 series, which provides 628 N push at the same pressure. For applications that never need stroke adjustment, a fixed-stroke SC32 cylinder is a simpler, cost-effective alternative. The SCJ32X30-30 replaces another AirTAC SCJ32 cylinder of the same bore, nominal stroke, and 30 mm adjust range with PT ports and basic mounting.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-30)
- ✓ 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 SCJ32X30-30 FAQ
At 0.5 MPa air pressure, the cylinder produces 402 N pushing and 345 N pulling. At the maximum operating pressure of 0.9 MPa, push force reaches 724 N. The pull force is lower because the 12 mm rod reduces the effective piston area on the return stroke.
Yes, if you need the field-adjustable stroke feature. The SCJ32X30-30 matches the bore and port size of an SC32, but the body is slightly longer to house the adjusting screw. Ensure your mounting arrangement can accommodate the 182 mm body length and that the 30 mm adjustment range suits your process.
