The AirTAC SAIJ80 Adjustable Cylinder SAIJ80AX95-50S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 95mm stroke, G3/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.
The AirTAC SAIJ80X95-50-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. The integrated -S magnet enables position sensing via AirTAC CMSE reed and DMSE electronic switches housed in the dual-side sensor grooves.
With a nominal 95mm stroke and a 50mm adjustment range, this SKU provides a highly flexible usable travel window of 45-95mm. You can fine-tune the retract end-position at commissioning without swapping the cylinder or adding external stops. It features a SUS420J2 stainless steel rod (option A) for superior corrosion resistance and uses PT tapered port threads.

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.

Dial in the exact 45-95mm retract distance during product size transitions without disassembling the tooling or changing the cylinder.
Use the 50mm rear adjuster to precisely set the final end-position during initial commissioning, absorbing mechanical tolerances instantly.
Choose this 80mm bore when 50mm (982N at 0.5MPa) lacks thrust, but 100mm (3927N at 0.5MPa) is physically oversized. The 50mm adjustment capacity is perfect for product-size changeovers on a line, allowing rapid end-stop tuning instead of mechanical rebuilds. The 25mm rod and M20x1.5 thread handle high side-load stresses well.
For any stroke over 300mm, an external guide is mandatory to prevent rod wear, though this 95mm travel is compact enough for self-support. Remember that the rear adjuster is a travel stop, not a lock; the SAIJ cannot hold loads without live air. For true load-holding, select the SAIL (air-released lock) or BSAI (clamp-lock) series. This SAIJ uses a reduced mounting set: Basic, FA, LB, TC, FTC, TCM1, TCM2 (omitting FB, CA, CB, CR).
Quick checklist
The rear adjuster screw lets you mechanically shorten the 95mm nominal stroke by up to 50mm. This creates a usable travel window of 45-95mm, allowing you to set the exact retract end-position without altering the cylinder mount.
