About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX150-30
The AirTAC SAIJ100X150-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 120 to 150 mm. It delivers 3927 N of push force and 3681 N of pull force at 0.5 MPa, making it suitable for heavy-duty positioning tasks. The extruded aluminum barrel features sensor grooves on both sides for flexible switch placement.
This configuration includes an SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and uses PT tapered port threads with a G1/2 connection. The rear adjustment screw acts purely as a mechanical stop to fine-tune the retract position during commissioning; it does not lock the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX150-30 Is Used
Machine Setup Tuning
Dial in the exact retract distance within the 120-150 mm window during initial commissioning to perfectly align heavy tooling without machining external stoppers.
Product Changeover
Quickly adjust the end-stop position by up to 30 mm on a packaging line when switching to a different product size, minimizing downtime between runs.
Heavy Load Positioning
Leverage the 3927 N push force at 0.5 MPa to move heavy pallets or fixtures into place, using the adjustable stroke to fine-tune the final resting location.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX150-30 the Right Cylinder?
Select this 100 mm bore when a smaller 80 mm cylinder (providing 2513 N push at 0.5 MPa) lacks the necessary thrust, but before stepping up to a 125 mm body. The 30 mm adjustment window is ideal for product changeovers, allowing you to shift the end position without swapping the cylinder or adding external stops. For load-holding without continuous air pressure, integrate an external rod lock or pilot-operated check valve, as the adjuster and air cushions only decelerate travel.
To match this ISO 15552 interchangeable cylinder, confirm the 150 mm stroke, 30 mm adjustment range, G1/2 PT port, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because this unit lacks the -S magnet option, it cannot host CMSE reed or DMSE electronic sensors without modification.
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 SAIJ100 Adjustable Cylinder SAIJ100AX150-30 FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder generates 3927 N of push force and 3681 N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 801 kgf.
The rear adjuster screw allows you to shorten the effective stroke from the nominal 150 mm down to 120 mm. This mechanical stop fine-tunes the end position during setup but does not hold the load dynamically without live air pressure.
