The AirTAC SAIJ200 Adjustable Cylinder SAIJ200X425-10 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 425mm 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 SAIJ200X425-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers immense thrust, pushing with 15708 N and pulling with 15080 N at 0.5 MPa. The integrated adjuster provides a usable travel window between 415 and 425 mm, allowing you to dial back the nominal 425 mm stroke by up to 10 mm during machine setup.
This extruded aluminum barrel design incorporates sensor grooves on both sides for flexible mounting of CMSE or DMSE switches. It features a robust 40 mm carbon steel rod with an M36x2 thread, providing excellent rigidity, and uses PT tapered port threads for secure pneumatic connections. The rear stopper mechanism allows precise end-position tuning at commissioning without swapping out the entire cylinder.

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.

Fine-tune the exact bottoming position of a 425 mm stroke press without mechanical disassembly, using the 10 mm rear adjuster to set precise end-stops for varying material thicknesses.
Rapidly adapt end-of-stroke positions during product size transitions on a heavy-duty conveyor, utilizing the adjustable travel window to accommodate new package dimensions instantly.
The adjustable stroke is ideal for product changeovers where exact end-stops must be fine-tuned on the fly, avoiding the need to bolt on external stops or replace a fixed-stroke SAI cylinder. To match this ISO 15552 replacement, specify the 200 mm bore, 425 mm stroke, 10 mm adjustment, PT G3/4 port, and your required mounting from the SAIJ subset (Basic, FA, LB, TC, FTC, TCM1, TCM2).
Because the 425 mm stroke is long and unsupported, an external guide is recommended to prevent excessive side-loading on the rod. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding without pressure, consider an external rod lock, a pilot-operated check valve, or the SAIL and BSAI cylinder series.
Quick checklist
At the maximum operating pressure of 1.0 MPa, it can deliver up to 3204 kgf.
The rear adjuster acts as an external stopper that allows you to shorten the effective stroke by up to 10 mm. This creates a usable travel window of 415 to 425 mm, enabling fine-tuning of the end position at commissioning without changing the cylinder.
