About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63X75-30S
The AirTAC SAIJ63X75-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 1559N of push force at 0.5 MPa. It features a carbon steel rod and a PT tapered port. Because of the 30mm adjustment code, this 75mm nominal stroke model yields a highly versatile 45-75mm usable travel window, letting you dial in the exact retract distance without swapping hardware.
The integrated -S magnet supports AirTAC CMSE reed and DMSE electronic sensors directly in the dual-side extruded barrel grooves. This adjustable variant retains the standard ISO 15552 mounting footprint but utilizes a focused mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2. The rear screw acts purely as a travel stop for end-position tuning, meaning it will not hold a load without continuous live air pressure.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63X75-30S Is Used
Changeover Calibration
Dial in the 45-75mm travel window during product size changeovers to perfectly seat parts without repositioning cylinder mounts.
End-Stop Tuning
Fine-tune the retract end position at machine commissioning using the rear screw, avoiding the need to machine custom external spacers.
Assembly Pressing
Deliver 1559N of pressing force while adjusting the exact bottoming depth on the fly to accommodate slight material thickness variations.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63X75-30S the Right Cylinder?
Choose this 63mm bore when you need 1559N of thrust at 0.5 MPa and require precise end-position tuning during commissioning. If your application needs less force, stepping down to a 50mm bore yields 982N; if you need more push, an 80mm bore provides 2513N. The 30mm adjustment window is perfect for product-size changeovers on a line, giving you a 45-75mm travel range without adding external stops. For load-holding without live pressure, you would need a SAIL or BSAI variant instead of relying on this adjuster. To match this ISO 15552 replacement exactly, specify the 63mm bore, 75mm stroke, 30mm adjustment, PT port, and -S magnet.
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 SAIJ63X75-30S FAQ
It features a rear adjusting screw that acts as a mechanical stop, allowing you to shorten the effective stroke by up to 30mm. This creates a 45-75mm usable travel window so you can fine-tune the retract position during setup without changing the cylinder.
At 0.5 MPa operating pressure, the 63mm bore provides 1559N of push force and 1402N of pull force. It can deliver up to 2805N of push force at its maximum 0.9 MPa pressure rating.
