About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX240-100S
The AirTAC SAIJ200X240-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 140-240 mm usable travel window. It delivers massive thrust, pushing 28274N at 0.9 MPa and 21991N at 0.7 MPa. This bore uses a G3/4 port and a 50 mm cushion length to manage heavy kinetic energy.
Equipped with a -S magnet, it integrates seamlessly with AirTAC DMSE solid-state and CMSE reed switches fitted into the dual sensor grooves. The rod is SUS420J2 stainless steel (code A) with an M36x2 thread, providing high side-load resistance, while the seals are standard TPU.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX240-100S Is Used
Heavy Press Fine-Tuning
Dial in the exact 140-240 mm travel window during heavy press setup to accommodate varying material thicknesses without adding external stops.
Product Changeover
Rapidly adjust the retract end-position on automated lines when switching product sizes, leveraging the 100 mm adjustment range for fast changeover.
Large Assembly Positioning
Use the massive 28274N push force to move and position heavy structural components, relying on the 50 mm cushion to soften the end of stroke.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX240-100S the Right Cylinder?
Choose this 200 mm bore when 160 mm (18095N push at 0.9 MPa) is insufficient for your heaviest positioning tasks. The 100 mm rear adjuster allows precise end-position tuning during commissioning or product changeover without swapping the cylinder. The rear screw acts purely as a travel stop for deceleration; it does not hold the load without live air. For load-holding without pressure, select the SAIL or BSAI series.
This unit is dimensionally interchangeable per ISO 15552. Exact replacement parameters: 200 mm bore, 240 mm nominal stroke, 100 mm adjustment range, PT tapered port threads, SUS420J2 rod, and a -S magnet. It supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.

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 SAIJ200AX240-100S FAQ
At 0.9 MPa it delivers 28274N of push force and 22620N of pull force. At 0.7 MPa the push force is 21991N. The maximum theoretical force at 1.0 MPa is 3204 kgf.
The rear adjuster screw lets you shorten the 240 mm nominal stroke by up to 100 mm, providing a usable travel window of 140 to 240 mm to fine-tune the retract end position during setup.
