The AirTAC Adjustable Cylinder SAIJ32 SAIJ32BX225-40 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 225mm 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 SAIJ32X225-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 185-225 mm usable travel window. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting.
This model utilizes a SUS304 stainless steel rod (option B) for enhanced corrosion resistance. The rear adjuster acts purely as a mechanical stop to dial in the end position during commissioning; it does not hold the load without live air pressure. For load-holding requirements, 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.
Dial in the exact 185-225 mm end position during commissioning without adding external physical stops to the machine frame.
Quickly retract the stroke by up to 40 mm to accommodate varying product lengths on a single production line.
Leverage the SUS304 stainless steel rod for light-duty positioning tasks in environments requiring higher corrosion resistance.
The 40 mm adjustment range is selected over a fixed-stroke SAI when you need variable end-stops for product changeovers without swapping cylinders. To match this ISO 15552 replacement, specify: 32x225 stroke, 40 mm adjust, PT port, Basic/FA/LB/TC/FTC/TCM1/TCM2 mountings, and no magnet.
Because the 225 mm stroke exceeds 300 mm? No, but for longer unsupported strokes, always use an external guide to prevent rod side-load wear. Note that the SAIJ mounting set omits FB, CA, CB, and CR brackets.
Quick checklist
The maximum operating pressure is 1.0 MPa.
The rear adjuster screw allows you to shorten the nominal 225 mm stroke by up to 40 mm, creating a 185-225 mm travel window. It functions only as an end-position stop and does not lock or hold the load without continuous air pressure.
