About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX180-30S
The AirTAC SAIJ100X180-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling you to fine-tune the effective travel within a 150-180 mm window. It delivers substantial thrust, providing 3927 N of push force at 0.5 MPa and up to 7068 N at 0.9 MPa. The integrated magnet (-S) supports position detection via CMSE reed or DMSE electronic sensors.
This model features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and uses a PT tapered G1/2 port. The rear adjustment screw acts purely as a mechanical stop to dial in the end position during commissioning; it does not lock or hold the load without live air pressure. For load-holding requirements without continuous air, consider the SAIL or BSAI series.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX180-30S Is Used
End-Position Tuning
Dial in the exact retract position within a 150-180 mm window during machine commissioning without adding external mechanical stops.
Product Changeover
Quickly adapt the cylinder's effective stroke on automated lines when processing different product sizes or thicknesses.
Heavy-Duty Positioning
Leverage the 7068 N push force at 0.9 MPa to move and position heavy pallets or fixtures with precise end-stop control.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX180-30S the Right Cylinder?
Choose this adjustable-stroke model when your machine setup requires variable end-stops or product-size changeovers without physically swapping the cylinder. If your application demands less force, stepping down to a 63 mm bore yields 1559 N at 0.5 MPa, whereas moving up to a 125 mm bore provides 6136 N.
To replace an existing ISO 15552 cylinder, verify the 100 mm bore, 180 mm nominal stroke, 30 mm adjustment range, G1/2 PT port, and the required -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, deliberately omitting FB, CA, CB, and CR. Because the 180 mm stroke is below the 300 mm threshold, side-load concerns are minimal, but always ensure the load is properly guided.
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 SAIJ100AX180-30S FAQ
At a 0.5 MPa operating pressure, it provides 3927 N of push force and 3681 N of pull force. At the maximum 0.9 MPa, the push force increases to 7068 N.
The rear adjuster screw lets you shorten the nominal 180 mm stroke by up to 30 mm, creating a usable travel window of 150-180 mm. The adjuster acts as a travel stop and does not lock the load without live air pressure.
