About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX225-10
The AirTAC SAIJ63X225-10 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 215 to 225 mm usable travel window, allowing you to dial back the nominal 225 mm stroke by up to 10 mm during commissioning. This bore delivers 1559 N pull force at 0.5 MPa and 2182 N push force at 0.7 MPa, making it suitable for medium-duty handling.
It features a SUS420J2 stainless steel rod and PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for CMSE reed or DMSE electronic switches. The rear adjuster acts as a travel stop to fine-tune the end position without adding external stops, but it does not lock the load without live air pressure.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX225-10 Is Used
Machine Setup
Dial in the exact 215 to 225 mm retract position during commissioning without machining external stoppers.
Product Changeover
Quickly adjust the end-stop by up to 10 mm on a packaging line when handling slightly different carton sizes.
Assembly Positioning
Fine-tune the stroke end-point to press or seat components accurately using the 2182 N push force at 0.7 MPa.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX225-10 the Right Cylinder?
Choose this 63 mm bore when your application requires 1559 N pull force at 0.5 MPa, stepping up from a 50 mm bore that provides 825 N pull. The 10 mm adjustment range is ideal for product changeovers where you need a variable end-stop rather than swapping a fixed-stroke SAI cylinder. For load-holding without live air, select a SAIL or BSAI cylinder instead, as the SAIJ adjuster is not a lock. This model is dimensionally interchangeable per ISO 15552 and uses PT ports with a Basic, FA, LB, TC, FTC, TCM1, or TCM2 mount.

- ✓ 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 SAIJ63AX225-10 FAQ
The rear adjuster screw lets you shorten the effective stroke by up to 10 mm, creating a 215 to 225 mm travel window. It acts as a mechanical stop to set the end position and does not lock the load without continuous air pressure.
At 0.5 MPa it provides 1559 N pull force and 1402 N push force. At 0.7 MPa the push force increases to 2182 N.
