The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32AX650-20 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 650mm 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 SAIJ32X650-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 630 to 650 mm usable travel window, allowing you to dial back the end position by up to 20 mm during commissioning without adding external stops.
This unit uses a SUS420J2 stainless steel rod for corrosion resistance and carries a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides, and the mounting interface supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets.

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 630 to 650 mm travel endpoint on the fly during product size transitions without swapping hardware.
Adjust the retract position precisely during line setup to accommodate varying package dimensions.
Trim the stroke by up to 20 mm to perfect the timing and positioning of assembly actuators.
Choose this 32 mm bore when you need precise end-position tuning on a 650 mm stroke but only moderate force. Because the stroke is 650 mm, the 12 mm rod needs external guidance to prevent excessive side-load wear on the seals.
The rear adjuster acts purely as a travel stop and works with the air cushions to decelerate the piston; it does not hold the load without live air. For load-holding without pressure, select a SAIL or BSAI cylinder instead. This model is dimensionally interchangeable per ISO 15552.
Quick checklist
A rear adjusting screw lets you shorten the effective travel from 650 mm down to 630 mm. This creates a 20 mm tuning window to set the exact retract end position during commissioning without changing the cylinder.
