About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX90-20S
The AirTAC SAIJ200X90-20-S is a double-acting ISO 15552 profile cylinder featuring a robust 200mm bore and a 90mm nominal stroke. A rear mechanical stopper allows you to trim the effective travel back by up to 20mm, creating a precise 70-90mm usable window for dialing in final end positions during commissioning. This adjustment is made directly on the cylinder without adding external stops.
Designed for heavy-duty tasks, it generates 15708N of push force and 15080N of pull force at 0.5MPa. The piston rod is manufactured from SUS420J2 stainless steel, offering high corrosion resistance, and the -S magnet enables position sensing with AirTAC CMSE reed and DMSE solid-state switches. It uses PT tapered ports and shares the exact mounting footprint of standard ISO 15552 cylinders.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX90-20S Is Used
Heavy Press Tuning
Dial in the exact 70-90mm travel window during machine setup to accommodate varying material thicknesses in heavy stamping and forming operations.
Product Changeover
Quickly adjust the end-stop position on automated assembly lines when switching between different product sizes without replacing the entire cylinder.
Sensor-Ready Actuation
Leverage the built-in -S magnet with DMSE electronic sensors to confirm end-of-stroke positions in automated heavy machinery control systems.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX90-20S the Right Cylinder?
Select this 200mm bore model when your application requires massive thrust that smaller bores cannot provide, such as heavy mold shifts or large press operations. If your force requirements are lower, stepping down to a 160mm bore yields 10053N of push force at 0.5MPa, which might better suit mid-weight handling. The adjustable 70-90mm travel window is ideal for production lines that undergo frequent product-size changeovers, removing the need to physically swap cylinders for slightly different stroke lengths.
Because the 90mm stroke is relatively short for this large bore, side-load risks are minimal, but the massive rod diameter (40mm with an M36x2 thread) handles high bending stresses well. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air pressure; for true load-holding, consider the SAIL or BSAI series. This configuration includes PT ports, SUS420J2 rod material, and a built-in magnet for sensors.

Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAIJ200 Adjustable Cylinder SAIJ200AX90-20S FAQ
At a 0.5MPa operating pressure, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. At the maximum 1.0MPa pressure, it can deliver up to 3204 kgf.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 90mm nominal stroke by up to 20mm, providing a usable travel window of 70-90mm. This allows fine-tuning of the end position without swapping the cylinder.
