About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX240-100S
The AirTAC SAIJ63X240-100-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. Equipped with a SUS420J2 stainless steel rod and a PT tapered port, it delivers 1559 N of push force and 1402 N of pull force at 0.5 MPa. The built-in magnet enables position detection with CMSE reed or DMSE electronic sensors.
This model provides a generous 140-240 mm usable travel window, allowing you to dial back the nominal 240 mm stroke by up to 100 mm. It is a true extruded aluminum profile cylinder, dimensionally interchangeable per ISO 15552, and utilizes variable air cushions at both ends to decelerate the load smoothly.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX240-100S Is Used
Product Changeover
Quickly reconfigure the retract distance on packaging lines handling different carton sizes using the 100 mm adjustment window.
End-Position Tuning
Fine-tune the exact end-of-stroke position during machine commissioning without swapping out the entire actuator.
Variable End Stops
Provide flexible physical stops for assembly presses that need to adapt to multiple part heights on the fly.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX240-100S the Right Cylinder?
Choose this 63 mm bore when a 50 mm bore (offering 982 N push at 0.5 MPa) lacks the necessary thrust, but an 80 mm bore (2513 N push) would be physically oversized. The 100 mm adjustment range is ideal for machines processing varying product sizes, letting you fine-tune the retract end position during changeovers without adding external stops. For holding loads without live air pressure, note that the rear adjuster acts only as a travel stop; you should instead specify an SAIL air-released lock or a BSAI clamp-lock cylinder.
Because the nominal stroke is 240 mm, standard side-load precautions apply, though an external guide is recommended if the load is unsupported. This SKU includes the -S magnet for CMSE / DMSE switches, uses a PT port thread, and supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR).

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 SAIJ63AX240-100S FAQ
The rear adjuster acts as a mechanical stop that lets you shorten the effective stroke by up to 100 mm. This creates a usable travel window of 140-240 mm, allowing precise end-position tuning without changing the cylinder.
At 0.5 MPa operating pressure, it provides 1559 N of push force and 1402 N of pull force. At 0.7 MPa, the push force increases to 2182 N.
