The AirTAC Adjustable Cylinder SAIJ32 SAIJ32BX550-10S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 550mm 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 SAIJ32X550-10-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 540-550mm usable travel window, letting you dial back the nominal 550mm stroke by up to 10mm during machine commissioning without adding external stops.
This specific SKU includes a SUS304 stainless steel rod for superior corrosion resistance and comes pre-fitted with a magnet for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel incorporates sensor grooves on both sides. While the rear adjuster fine-tunes the retract position, remember it acts only as a travel stop and does not hold the load without live air pressure.

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 540-550mm retract end-stop precisely during setup, absorbing mechanical tolerance variations without hardware changes.
Quickly adjust the stroke by up to 10mm to accommodate slightly different product sizes on a packaging line.
Utilize the 12mm SUS304 stainless steel rod for light-duty pushing tasks in environments where corrosion resistance is required.
The 10mm adjustment window is ideal for product changeovers on a line, preventing the need to physically swap cylinders for minor length differences. If you need higher force, stepping up to a 40mm bore yields 628N, whereas dropping to a smaller bore would reduce your thrust significantly.
For any stroke length of 550mm, side-load management is critical. The 12mm rod and M10x1.25 thread handle moderate loads, but you must use an external guide to prevent rod binding over this extended travel. This SAIJ model uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets. If your application requires true load-holding without continuous air supply, consider the SAIL or BSAI series instead.
Quick checklist
The rear adjuster acts as a mechanical stop that lets you shorten the effective stroke by up to 10mm, providing a 540-550mm travel window. It only sets the end position; it does not lock or hold the load without live air pressure.
The operating speed range is 30-800mm/s, and it features variable air cushions at both ends to decelerate the piston.
