The AirTAC SAIJ80 Adjustable Cylinder SAIJ80AX150-50 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 150mm 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 SAIJ80X150-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that trims the effective travel back by up to 50 mm. This yields a usable stroke window of 100 to 150 mm, allowing precise end-position tuning at commissioning without swapping hardware.
The 25 mm carbon steel rod normally pairs with an M20x1.5 thread, but this specific configuration uses a SUS420J2 stainless steel rod (option A) for improved corrosion resistance. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 retract stop from 100 to 150 mm during machine setup to accommodate varying material thicknesses without external stop blocks.
Quickly shift the effective stroke by up to 50 mm when switching between different product sizes on a packaging line, minimizing downtime.
The 50 mm adjustment range lets you dial in the exact travel window between 100 and 150 mm on the fly. For fixed travel without commissioning tweaks, a standard SAI cylinder is simpler. Remember that the rear adjuster is a stop, not a lock; if you need fail-safe load holding without live air, select a SAIL or BSAI cylinder instead.
When replacing an ISO 15552 cylinder, match the 80 mm bore, 150 mm nominal stroke, 50 mm adjustment range, G3/8 port, and your required mounting interface. This SKU lacks the -S magnet, so it cannot host CMSE or DMSE sensors without modification. Although 150 mm is a moderate stroke, the 25 mm rod and M20x1.5 thread handle side loads well, but always guide the load externally to prevent binding.
Quick checklist
At the maximum 1.0 MPa pressure, it can deliver up to 513 kgf.
A rear external stopper screw lets you shorten the nominal 150 mm stroke by up to 50 mm, creating an adjustable travel window between 100 and 150 mm. This stopper only sets the end position; it does not lock or hold the load without continuous air pressure.
