About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX30-30
The AirTAC SAIJ200X30-30 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers immense thrust, pushing 15708 N and pulling 15080 N at 0.5 MPa. The integrated rear stopper screw provides a 0-30 mm usable travel window, allowing you to fine-tune the extend position on the fly without adding external stops.
Built with an SUS420J2 stainless steel rod (code A) and PT tapered ports, this extruded aluminum barrel cylinder operates at 30-500 mm/s. The rear adjuster acts strictly as a travel stop for end-position tuning, not a lock, meaning it cannot hold a load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX30-30 Is Used
Press Stroke Tuning
Dial in the exact 0-30 mm extension during machine commissioning to perfectly set the pressing distance for heavy-duty assembly operations.
Product Changeover
Quickly adjust the extend end-stop on a production line when switching between product variants, avoiding the need to physically swap out the entire cylinder.
Heavy Positioning
Leverage the 15708 N push force at 0.5 MPa to move and position heavy pallets or molds, while relying on the rear screw to set the final resting coordinate.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX30-30 the Right Cylinder?
Choose this 200 mm bore adjustable-stroke cylinder when your application requires extreme force alongside variable end-stop positioning during machine setup or product changeover. If you need slightly less thrust, stepping down to a 160 mm bore yields 10053 N push force at 0.5 MPa. For load-holding without continuous air pressure, this plain SAIJ model is insufficient; consider an external rod lock, or explore the SAIL (air-released lock) or BSAI (clamp-lock) variants.
To replace an ISO 15552 cylinder, match the 200 mm bore, 30 mm nominal stroke, 30 mm adjustment, PT G3/4 port, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that FB, CA, CB, and CR mounts are omitted from this adjustable series.
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 SAIJ200AX30-30 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 the maximum 1.0 MPa pressure, it can deliver up to 3204 kgf.
The rear adjuster screw lets you shorten the 30 mm nominal stroke by up to 30 mm, creating a 0-30 mm usable travel window. It functions as a mechanical stop for end-position tuning and does not lock the load without live air.
