The AirTAC Airtac SAIJ100 Adjustable Cylinder SAIJ100X350-100S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 350mm stroke, G1/2 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.
The AirTAC SAIJ100X350-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear mechanical stroke adjuster. It delivers a substantial 3927 Newtons of push force at 0.5 MPa and features a built-in magnet for position sensing. By turning the rear screw, you can dial back the 350 mm nominal stroke by up to 100 mm, creating a precise 250-350 mm usable travel window without adding external stops.
This adjuster acts purely as a travel stop for end-position tuning and relies on live air to hold the load, meaning it is not a locking device. For load-holding without air pressure, you would need an external rod lock or a different series like SAIL. The 25 mm carbon steel piston rod and M20x1.5 thread provide robust resistance to side loads, though the 350 mm stroke still warrants an external guide rail to prevent binding.

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.
Quickly fine-tune the end stop from 250 to 350 mm during packaging format changes without disassembling the machine.
Delivers up to 5497 N of push force at 0.7 MPa for pressing bearings or components securely into place.
Ideal for conveyor lines processing varying pallet sizes, allowing the stroke to adapt to different product widths.
Choose this 100 mm bore when your application requires heavy thrust around 3927 N at 0.5 MPa, stepping up from a 80 mm bore that offers 2513 N. The adjustable stroke is highly beneficial for machine setups requiring frequent product changeovers, allowing you to fine-tune the end position on the fly rather than swapping out a fixed-stroke SAI cylinder. Because the stroke is 350 mm, mounting should include an external guide to manage side loads and prevent rod deflection.
To match this exact configuration for an ISO 15552 interchange, specify a 100 mm bore, 350 mm stroke, up to 100 mm rear adjustment, PT tapered port threads, and the -S magnet option for use with CMSE reed and DMSE electronic sensors. The available mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2.
Quick checklist
The rear adjuster is a mechanical stopper that lets you trim the effective travel back by up to 100 mm, providing a 250-350 mm operating window. It sets the end position but does not lock the load without continuous air pressure.
At a standard 0.5 MPa operating pressure, it provides 3927 Newtons of push force and 3681 Newtons of pull force. At 0.7 MPa, the push force increases to 5497 Newtons.
