The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32AX400-40 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 400mm stroke, G1/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.
The AirTAC SAIJ32X400-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 360-400mm usable travel window. The PT tapered ports and M10x1.25 rod thread ensure straightforward integration.
This model uses a SUS420J2 stainless steel rod (option A) for improved corrosion resistance. The rear adjuster acts strictly as a travel stop to set deceleration, not a lock, so it will not hold the load without live air. For load-holding needs, consider the SAIL or BSAI series instead.

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 360-400mm travel window during initial commissioning to perfectly dial in the end-stop position without external spacers.
Quickly adjust the stroke length on packaging lines when handling different product sizes, using the 40mm rear trim range.
Dial back the nominal 400mm stroke to 360mm to accommodate varying material lengths or push distances on the fly.
If you need more force, stepping up to the 40mm bore yields 628N. The 40mm adjustment range is perfect for machine setups requiring variable end-stops during product changeovers. Since this is a 400mm stroke, an external guide is highly recommended to prevent excessive side-loading on the M10x1.25 rod.
When matching ISO 15552 dimensions, specify a 32mm bore, 400mm stroke, 40mm adjustment, PT port threads, and no magnet. The mounting set is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB and CA options.
Quick checklist
The rear adjuster screw allows you to shorten the effective travel from the nominal 400mm down to 360mm. This stopper fine-tunes the retract end position but does not lock the load without live air pressure.
