About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X290-10S
The AirTAC SAIJ100X290-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 3927N of push force at 0.5 MPa. It features a carbon steel rod and a PT tapered port thread. The built-in magnet enables position detection with CMSE reed or DMSE electronic sensors.
This model provides a 280-290mm usable travel window, allowing you to trim the nominal 290mm stroke by up to 10mm during commissioning. It uses variable air cushions at both ends to manage deceleration, while the rear stopper lets you dial in the exact retract position without adding external stops.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X290-10S Is Used
Product Changeover
Dial in the exact 280-290mm end stop during machine setup to accommodate different product sizes without swapping hardware.
End-Position Tuning
Fine-tune the retract distance by up to 10mm at commissioning to perfect the alignment of heavy mechanical assemblies.
Assembly Line Calibration
Adjust the stroke window on the fly to compensate for mechanical wear or sensor drift in automated manufacturing cells.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X290-10S the Right Cylinder?
Choose this 100mm bore when an 80mm cylinder lacks thrust; an SAIJ80 yields 2513N push at 0.5 MPa, whereas this 100mm unit provides 3927N. The adjustable 280-290mm travel window is perfect for applications requiring precise end-position tuning on product changeovers, rather than swapping a fixed-stroke SAI cylinder. Because the 290mm stroke exceeds 300mm, ensure adequate external guiding to handle side loads.
For an exact ISO 15552 replacement, match the 100mm bore, 290mm stroke, 10mm adjustment, PT port thread, and -S magnet. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for pilot-operated locking, consider the SAIL or BSAI series. SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.
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 SAIJ100X290-10S FAQ
At 0.5 MPa operating pressure, this 100mm bore cylinder provides 3927N of push force and 3681N of pull force. At 0.7 MPa, the push force increases to 5497N.
The rear adjuster screw allows you to shorten the effective travel from the nominal 290mm down to 280mm, creating a 280-290mm usable window. This stopper sets the retract end position but does not lock the load without continuous air pressure.
