The AirTAC SAIJ160 Adjustable Cylinder SAIJ160BX140-50 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 140mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.
The AirTAC SAIJ160X140-50 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. The built-in rear stopper allows you to trim the nominal 140mm stroke back by up to 50mm, creating a precise 90-140mm usable travel window for exact end-position tuning during commissioning.
This heavy-duty actuator features a SUS304 stainless steel rod (option B) for superior corrosion resistance and uses PT tapered port threads (G3/4) for sealed pneumatic connections. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement. Operating at speeds of 30-500mm/s, it uses variable air cushions at both ends to decelerate the load smoothly. The rear adjuster functions strictly 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.
Dial the 50mm adjuster back during setup to perfectly time the 90-140mm travel window, ensuring the 10053N clamping force hits the material without bottoming out hard.
Quickly reconfigure the end-stop position on a packaging conveyor when box dimensions change, shifting the effective stroke from 140mm down to 90mm without changing hardware.
Use the rear stopper to fine-tune the final resting position of heavy pallets, relying on the 40mm SUS304 rod to withstand harsh industrial environments.
Choose this 160mm bore when an application requires substantial thrust—delivering 10053N at 0.5MPa—exceeding the 6136N capacity of the 125mm bore, but without stepping up to the massive 15708N of the 200mm class. The 50mm adjustment range is ideal for product changeovers on packaging lines, allowing operators to dial in a new end-stop position between 90 and 140mm without swapping the cylinder or adding external mechanical stops. For any load-holding requirements without live air pressure, select a SAIL (air-released lock) or BSAI (clamp-lock) cylinder instead, as the SAIJ adjuster is only a stop.
To replace this ISO 15552 cylinder, match the 160mm bore, 140mm stroke, 50mm adjustment range, PT G3/4 port, and SUS304 (B) rod material. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. Although the 140mm stroke is short, the 40mm rod and M36x2 thread provide high rigidity, but heavy lateral loads should still be guided externally to prevent binding.
Quick checklist
At its maximum 1.0MPa pressure, it delivers up to 2050 kgf of thrust.
The rear adjuster screw acts as an external stopper that lets you shorten the 140mm nominal stroke by up to 50mm. This provides a usable travel window between 90mm and 140mm, allowing you to fine-tune the end position without altering the cylinder mounting.
