About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX270-10S
The AirTAC SAIJ200X270-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 260 to 270 mm from its 270 mm nominal stroke. Delivering 15708 N of push force at 0.5 MPa, this massive 200 mm bore unit is built for heavy-duty positioning. The extruded aluminum barrel features sensor grooves on both sides, and this -S variant includes a magnet for use with AirTAC CMSE reed and DMSE electronic solid-state switches.
This model features a SUS420J2 stainless steel rod (option A) and PT tapered port threads (G3/4) for high-strength pneumatic connections. The rear adjuster functions purely as a mechanical stop to fine-tune the retract end position during commissioning; it is not a lock and cannot hold the load without live air pressure. For load-holding requirements without continuous air, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX270-10S Is Used
Heavy Press Tuning
Dial in the exact 260-270 mm retract position on heavy stamping or press equipment during initial commissioning without external stopper blocks.
Product Changeover
Quickly adjust the end-stop by up to 10 mm on automated lines when switching between product variants that require slightly different retraction depths.
Pallet Positioning
Fine-tune the retract stop for large pallet handling systems, ensuring massive 15708 N thrust aligns heavy loads precisely to downstream stations.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX270-10S the Right Cylinder?
Choose this 200 mm bore cylinder when your application requires the 15708 N push force at 0.5 MPa and precise mechanical end-stop tuning. Stepping down to the 160 mm bore reduces the push force to 10053 N, while the 200 mm bore provides the necessary thrust for moving heavy assemblies. The 10 mm adjustable window is ideal for dialing in exact retract positions during machine setup or product changeover without adding external stops. To replace an ISO 15552 cylinder, match the 200 mm bore, 270 mm stroke, 10 mm adjustment, PT G3/4 port, and -S magnet. Because the stroke is 270 mm, an external guide is recommended to prevent excessive side-loading on the unsupported rod. SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, omitting FB, CA, CB, and CR options.

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 SAIJ200AX270-10S FAQ
At 0.5 MPa, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. The maximum operating pressure is 1.0 MPa, yielding up to 3204 kgf. The operational speed range is 30-500 mm/s.
The rear adjuster acts as a mechanical stop that lets you trim the effective travel back by up to 10 mm from the 270 mm nominal stroke, creating a 260-270 mm usable window. It only sets the travel end and does not lock or hold the load without live air pressure.
