About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX110-30S
The AirTAC SAIJ63X110-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering a robust 1402N pull force at 0.5 MPa. An integrated magnet (-S) enables precise position detection using CMSE reed or DMSE electronic solid-state switches. This specific configuration features a SUS420J2 stainless steel rod (code A) and PT tapered port threads, making it highly suitable for environments where corrosion resistance is necessary.
The built-in rear stopper allows you to fine-tune the effective travel down from the 110mm nominal stroke, providing an exact 80-110mm usable window. This on-the-fly tuning eliminates the need to swap cylinders or bolt on external stops during machine commissioning or product changeovers. It retains the standard extruded aluminum barrel with sensor grooves on both sides and uses a reduced mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX110-30S Is Used
Machine Setup Tuning
Dial in the exact 80 to 110mm end-position during initial commissioning without physically swapping out the cylinder or adding external mechanical stops.
Product Size Changeovers
Quickly adapt the cylinder's stroke window on packaging lines when processing different product sizes, minimizing downtime between production runs.
Corrosive Assembly Stations
Leverage the SUS420J2 stainless steel rod and PT tapered ports for reliable actuation in light-corrosive or washdown manufacturing environments.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX110-30S the Right Cylinder?
Choose this 63mm bore when your application requires more force than a 50mm cylinder (which offers 825N pull at 0.5 MPa) but less bulk than an 80mm option (2268N pull). The adjustable stroke is ideal for setups needing a variable end-stop to dial in final positions without hardware changes. For a fixed travel without the rear adjuster, the standard SAI cylinder is a simpler alternative.
Because the 110mm stroke is relatively short, side-load stress on the 20mm rod and M16x1.5 thread is minimal, though external guides are always recommended for heavy lateral loads. Remember that the rear adjuster acts only as a travel stop and the air cushions only decelerate the load; neither will hold a load without live air pressure. For true load-holding, consider the SAIL or BSAI series. This model is dimensionally interchangeable with ISO 15552 cylinders.
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 SAIJ63AX110-30S FAQ
At a standard operating pressure of 0.5 MPa, this 63mm bore cylinder provides 1559N of push force and 1402N of pull force. It can reach a maximum push force of 2805N at 0.9 MPa.
The rear adjusting screw acts as a mechanical stop that lets you shorten the nominal 110mm stroke by up to 30mm. This creates a usable travel window of 80 to 110mm, allowing precise end-position tuning without replacing the cylinder.
