The AirTAC SAIJ100 Adjustable Cylinder SAIJ100AX105-75 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 105mm stroke, G1/2 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.
The AirTAC SAIJ100X105-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal stroke of 105 mm with a usable travel window of 30-105 mm, allowing you to dial back the extend position by up to 75 mm during commissioning. Equipped with a robust 25 mm rod and M20x1.5 thread, it handles heavy loads with a maximum push force of 801 kgf at 1.0 MPa.
This unit features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance in humid environments. The extruded aluminum barrel includes sensor grooves on both sides, ready for CMSE reed or DMSE electronic switches if a magnet is added later. The rear adjuster functions strictly as a mechanical stop to fine-tune the end position without holding the load pneumatically.

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.

Quickly reposition the end-stop within the 30-105 mm window when switching product sizes on a packaging line, avoiding physical cylinder swaps.
Dial in the exact 75 mm retraction depth during commissioning to perfect pressing force without adding bulky external mechanical stops.
The adjustable 30-105 mm window is perfect for product changeovers where exact end-of-stroke positioning varies. For applications requiring true load-holding without live air pressure, select the SAIL or BSAI series instead, as the SAIJ adjuster is a stop, not a lock. The PT G1/2 port and 25 mm rod manage high side loads, but any stroke over 300 mm requires an external guide; this 105 mm stroke is safely self-supported.
Quick checklist
The maximum push force is 801 kgf at 1.0 MPa.
The rear adjuster acts as a mechanical stop that trims the effective travel from the 105 mm nominal stroke down to as little as 30 mm. It sets the end position but does not lock the load without live air pressure.
