About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX1000-30
The AirTAC SAIJ63X1000-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 970 to 1000 mm, letting you dial back the nominal stroke by up to 30 mm during machine commissioning. The 63 mm bore generates 1559 N of push force at 0.5 MPa, fitting medium-duty positioning tasks.
This unit uses a SUS420J2 stainless steel rod for corrosion resistance and features PT tapered port threads (G3/8). The extruded aluminum barrel includes sensor grooves on both sides for mounting switches. Because the stroke reaches 1000 mm, an external guide rail is strongly recommended to prevent excessive side-loading on the rod.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX1000-30 Is Used
Long-Stroke Component Pushing
Pushes parts across a 1000 mm span with a 970-1000 mm adjustable window, allowing exact end-position trimming for varying product lengths.
Transfer Line Diverter
Diverts packages on a transfer line, using the 30 mm stroke reduction to fine-tune the diverter arm reach without adding external hard stops.
Machine Setup Changeover
Speeds up product changeovers on automated machinery by letting operators dial in the exact retract end-position via the rear screw.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX1000-30 the Right Cylinder?
Select this 63 mm bore when your application requires moderate thrust (1559 N push at 0.5 MPa) and a highly extended travel distance. If you need less force, stepping down to a 50 mm bore yields 982 N; stepping up to an 80 mm bore provides 2513 N. The adjustable rear stopper is chosen over a fixed SAI cylinder when you need variable end-stops for product changeovers without physically swapping components.
When ordering, specify the 63 mm bore, 1000 mm stroke, 30 mm adjustment, PT port thread, and SUS420J2 rod material. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air pressure; for dead-stop load holding, consider an external rod lock or the AirTAC SAIL series. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX1000-30 FAQ
At 0.5 MPa operating pressure, this 63 mm bore cylinder provides 1559 N of push force and 1402 N of pull force. At the maximum 1.0 MPa pressure, it delivers up to 318 kgf.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective travel from 1000 mm down to 970 mm. It allows fine-tuning of the end position during setup but does not lock the load without continuous air pressure.
