About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX100-10S
The AirTAC SAIJ63X100-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 90 to 100 mm for precise end-position tuning. It delivers a robust 1559 N push force at 0.5 MPa and utilizes a SUS420J2 stainless steel rod for enhanced corrosion resistance. The integrated magnet (-S) supports CMSE reed and DMSE electronic sensors, fitting neatly into the standard dual-side sensor grooves.
This 63 mm bore model features PT tapered port threads (G3/8) and reaches speeds of 30-800 mm/s. The rear adjustment screw allows you to dial in the retract end-stop at commissioning without adding external stops, though it functions purely as a travel stop and will not hold the load without live air pressure.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX100-10S Is Used
End-Position Tuning
Dial in the exact 90 to 100 mm retract stop during machine commissioning to compensate for mechanical tolerances without swapping cylinders.
Product Changeover
Quickly adjust the stroke end-stop by up to 10 mm when running a new product size on the line, minimizing setup downtime.
Assembly Positioning
Leverage the 1559 N push force and fine travel adjustment to seat components accurately before a secondary operation occurs.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX100-10S the Right Cylinder?
Select this 63 mm bore model when your application requires a 1559 N push force at 0.5 MPa, stepping up from a 50 mm bore (982 N) for heavier payloads, or down from an 80 mm bore (2513 N) to save space. The 10 mm adjustable window is ideal for product changeovers where exact end-of-stroke positioning varies slightly. For load-holding without continuous air pressure, consider the SAIL or BSAI series instead of relying on the adjuster. To match this cylinder for an ISO 15552 replacement, verify the 63x100 dimensions, 10 mm adjustment, G3/8 PT ports, and the -S magnet requirement.
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 SAIJ63AX100-10S FAQ
At 0.5 MPa operating pressure, this 63 mm bore cylinder provides a 1559 N push force and a 1402 N pull force. It can reach a maximum push force of 2805 N at 0.9 MPa.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the nominal 100 mm stroke by up to 10 mm, creating a 90-100 mm usable travel window. It is a travel stop, not a lock, and requires live air to hold the load.
