About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX100-30
The AirTAC SAIJ63X100-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 70-100 mm, letting you dial back the nominal 100 mm stroke by up to 30 mm during commissioning. In the 63 mm bore class, it delivers a 1559 N pull force at 0.5 MPa and up to 2805 N push at 0.9 MPa.
This variant uses a SUS420J2 stainless steel rod for superior corrosion resistance compared to standard carbon steel. It features PT tapered port threads (G3/8) and operates without a magnet. The rear adjuster acts strictly as a travel stop for end-position tuning, not a load-holding lock, meaning live air pressure is always required to maintain position.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX100-30 Is Used
End-Stop Calibration
Dial in the exact 70-100 mm travel window during machine commissioning to perfect end-position tuning without swapping cylinders.
Product Changeover
Quickly adjust the rear stopper by up to 30 mm to accommodate new product sizes on a packaging line, reducing downtime.
Assembly Positioning
Leverage the 1559 N pull force to press and position components, fine-tuning the stroke to avoid overtravel and part damage.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX100-30 the Right Cylinder?
Choose this 63 mm bore adjustable cylinder when your application requires precise end-stop tuning without adding external stops, delivering a 1559 N pull force at 0.5 MPa. If your setup needs less force, stepping down to a 50 mm bore yields 825 N of pull force, while moving up to an 80 mm bore provides 2268 N. For exact ISO 15552 replacement matching, confirm the 100 mm stroke, 30 mm adjustment range, PT G3/8 port, and the absence of a magnet (-S).
Because the stroke is 100 mm, the 20 mm rod diameter handles side loads well without needing an external guide. Remember that the SAIJ rear adjuster only sets the travel end; if you need true load-holding without continuous air pressure, consider an AirTAC SAIL pneumatic lock or BSAI clamp-lock cylinder instead. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.
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 SAIJ63AX100-30 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 0.9 MPa, the push force increases to 2805 N.
The rear adjuster screw lets you shorten the effective travel from the nominal 100 mm down to 70 mm, creating a 70-100 mm usable window. This stopper only sets the end position and does not lock the load without live air pressure.
