About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX110-75S
The AirTAC SAIJ63X110-75-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. By turning the external stopper screw, you can trim the nominal 110 mm stroke back by up to 75 mm, creating a highly flexible 35 to 110 mm usable travel window for on-the-fly machine changeovers. This bore size delivers 1559 N of push thrust at 0.5 MPa and 2182 N at 0.7 MPa, making it well-suited for medium-force positioning tasks.
Configured for harsher environments, this unit features a SUS420J2 stainless steel rod (material code A) and includes a built-in magnet for position sensing with CMSE reed or DMSE electronic switches. The extruded aluminum barrel provides sensor grooves on both sides, and the PT tapered port threads (G3/8) ensure a tight pneumatic connection. Remember that the rear adjuster acts purely as a mechanical stop to set the end position; it does not lock or hold the load without continuous live air pressure.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX110-75S Is Used
Variable End-Stop Positioning
Dial in the exact retract distance between 35 and 110 mm during machine setup to accommodate varying product lengths without changing out the actuator.
Product Size Changeover
Rapidly adjust the stroke end-point on packaging lines when switching between different package formats, minimizing downtime and mechanical retooling.
Medium-Force Forming
Leverage the 2182 N push force at 0.7 MPa for light pressing or seating operations, using the rear screw to fine-tune the final depth precisely.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX110-75S the Right Cylinder?
Choose this SAIJ63X110-75-S when your application requires frequent end-position tuning across a wide 35 to 110 mm range without swapping cylinders or adding external stops. If you need less force, stepping down to a 50 mm bore yields 982 N of push thrust at 0.5 MPa. For heavier loads, an 80 mm bore provides 2513 N at the same pressure. Because the nominal stroke is 110 mm, side-load risks are minimal, but always ensure the M16x1.5 rod thread is properly aligned to prevent premature seal wear.
When specifying a replacement, match the 63 mm bore, 110 mm nominal stroke, 75 mm adjustment range, PT port threads, and the -S magnet requirement. The SAIJ mounting interface supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 accessories, deliberately omitting FB, CA, CB, and CR brackets. If your process demands true load-holding without live air, select an SAIL pneumatic lock or BSAI clamp-lock cylinder instead of relying on this adjuster.

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 SAIJ63AX110-75S FAQ
It features a rear mechanical stopper screw that lets you shorten the effective travel from the 110 mm nominal stroke by up to 75 mm. This creates a usable end-position window between 35 and 110 mm, allowing precise tuning at commissioning without external stops.
At 0.5 MPa operating pressure, it provides 1559 N of push thrust and 1402 N of pull thrust. If you increase the supply to 0.7 MPa, the push force rises to 2182 N.
