The AirTAC SAIJ100 Adjustable Cylinder SAIJ100AX155-10S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 155mm stroke, G1/2 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.
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. 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.

Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Related SAI-family variants: SAID (double rod), SAIJ (adjustable stroke), SAIL (with lock), SAIF (with valve), BSAI (enclasp / clamp-lock), and SAI-S with built-in magnet. Rod material: carbon steel (blank) / SUS420J2 (A) / SUS304 (B); seals: TPU (blank) / Viton H / NBR N.
Fine-tune the 145-155 mm travel window during setup to achieve exact end-positioning without adding external mechanical stops.
Quickly adjust the retract end-stop by up to 10 mm on automated lines when switching between slightly different product sizes.
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
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.
It can deliver a maximum push force of 801 kgf at 1.0 MPa.
