Airtac SAIJ200 Adjustable Cylinder SAIJ200AX90-30
The AirTAC Airtac SAIJ200 Adjustable Cylinder SAIJ200AX90-30 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 90mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX90-30
The AirTAC SAIJ200X90-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 60-90 mm usable travel window from its 90 mm nominal stroke. Built with a robust 40 mm SUS420J2 stainless steel rod and PT tapered ports, it delivers a massive 15080 N pull force at 0.5 MPa and reaches a maximum of 3204 kgf at 1.0 MPa.
Because the external stopper acts on the retract end, you can dial in the precise end position during commissioning without adding external stops. The extruded aluminum barrel includes sensor grooves on both sides, and the mounting interface uses a reduced set of ISO 15552 attachments (Basic, FA, LB, TC, FTC, TCM1, TCM2) omitting the FB, CA, CB, and CR options.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX90-30 Is Used
Heavy Machinery Changeover
Dial in the 60-90 mm travel window during heavy equipment setup to accommodate different part sizes without replacing the entire cylinder.
High-Force Positioning
Leverage the 3204 kgf maximum thrust to move heavy assemblies, using the rear stopper to precisely set the retract position at commissioning.
Adjustable End Stops
Fine-tune the retract stroke by up to 30 mm on automated lines, eliminating the need to bolt on external physical stops during layout adjustments.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX90-30 the Right Cylinder?
Choose this 200 mm bore when your application requires extreme thrust that a 160 mm bore cannot provide, as the smaller bore yields 9425 N of pull force at 0.5 MPa compared to this cylinder's 15080 N. An adjustable stroke is ideal for product-size changeovers on a line, allowing you to fine-tune the end stop on the fly rather than swapping to a fixed-stroke SAI cylinder.
Note that the rear adjuster is a travel stop, not a lock; this SAIJ cannot hold a load without live air pressure, so for fail-safe load holding you should consider an external rod lock or the SAIL cylinder series. When matching ISO 15552 replacements, ensure you specify the PT port thread, the SUS420J2 rod material, the 30 mm adjustment range, and the correct mounting bracket.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
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 SAIJ200AX90-30 FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At its maximum 1.0 MPa pressure, it can deliver up to 3204 kgf.
The SAIJ200X90-30 has a 90 mm nominal stroke with a rear adjuster that allows you to shorten the effective travel by up to 30 mm, creating a 60-90 mm usable window. The adjuster acts as a mechanical stop to fine-tune the end position and does not lock the load without live air pressure.
