About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX155-10S
The AirTAC SAIJ100X155-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 145-155 mm usable travel window, letting you dial back the stroke by up to 10 mm during machine commissioning. Delivering 7068N of push force at 0.9 MPa, it handles heavy actuation tasks. This variant features a SUS420J2 stainless steel rod and a built-in magnet for position sensing.
The extruded aluminum barrel includes sensor grooves on both sides, supporting AirTAC CMSE reed and DMSE electronic switches. You can fine-tune the retract end-position without bolting on external stops. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX155-10S Is Used
Machine Commissioning
Fine-tune the 145-155 mm travel window during setup to achieve exact end-positioning without adding external mechanical stops.
Product Changeover
Quickly adjust the retract end-stop by up to 10 mm on automated lines when switching between slightly different product sizes.
Heavy Assembly Press
Leverage the 7068N push force at 0.9 MPa for heavy pressing tasks, using the SUS420J2 stainless steel rod for durability.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX155-10S the Right Cylinder?
Select this 100mm bore cylinder when your application requires 7068N of push force at 0.9 MPa and a 145-155 mm travel window. If you need less force, the 80mm bore provides 4523N. If you require more, the 125mm bore yields 11045N. An adjustable stroke is ideal for setups needing exact end-position tuning at commissioning or during product changeover, avoiding the need to swap out a fixed-stroke SAI cylinder.
For ISO 15552 replacement matching, verify the 100mm bore, 155mm nominal stroke, 10mm adjustment, PT tapered port thread, and the -S magnet option. Because the stroke is 155mm, side-load is minimal, but long unsupported loads still require an external guide. To hold a load without live air, use a SAIL or BSAI cylinder instead of relying on the rear stopper.
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 SAIJ100AX155-10S FAQ
It features a rear adjusting screw that lets you shorten the effective stroke by up to 10 mm, creating a 145-155 mm usable travel window. The adjuster acts as a travel stop and does not lock or hold the load without live air pressure.
At 0.9 MPa, the cylinder provides a push force of 7068N and a pull force of 3681N. It can deliver a maximum push force of 801 kgf at 1.0 MPa.
