About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX290-30S
The AirTAC SAIJ200X290-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that lets you trim the effective travel back by up to 30 mm. This creates a usable 260-290 mm stroke window, allowing precise end-position tuning at commissioning without swapping out the barrel or bolting on external stops. As the largest bore in the series, it delivers massive thrust, pushing with 21991 N and pulling with 15080 N at 0.7 MPa.
This SKU is built for position sensing, shipping with a magnet (-S) that works seamlessly with AirTAC CMSE reed and DMSE electronic sensors fitted into the dual-side barrel grooves. It features a SUS420J2 stainless steel rod (option A) for improved corrosion resistance and uses PT tapered port threads. Remember that the rear adjuster acts only as a travel stop; it does not hold the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX290-30S Is Used
Heavy Pressing
Delivers up to 28274 N of push force at 0.9 MPa for assembly and forming tasks requiring precise end-position tuning.
Product Changeover
Dial the stroke back 30 mm during line changeovers to accommodate different part lengths without changing the cylinder.
Large Fixture Actuation
Moves heavy industrial fixtures and gates, using the 260-290 mm adjustable window to perfect the resting position.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX290-30S the Right Cylinder?
Choose this 200 mm bore when your application demands maximum force in the SAIJ range, such as heavy pressing or large-gate actuation. If you do not need 21991 N of push force at 0.7 MPa, stepping down to a 160 mm bore saves space and air consumption while still providing 14074 N. The adjustable 260-290 mm travel is ideal for production lines running multiple product sizes, letting operators dial in the exact end-stop during changeover instead of re-engineering the fixture.
When ordering an ISO 15552 replacement, match the 200 mm bore, 290 mm nominal stroke, 30 mm adjustment range, PT port thread, and the -S magnet requirement. Because the 290 mm stroke is long and the 40 mm rod is heavy, an external guide is recommended to prevent excessive side-loading on the rod and rod thread. For applications requiring true load-holding without live air, the rear stopper here is insufficient; look to the SAIL or BSAI clamp-lock series instead.
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 SAIJ200AX290-30S FAQ
At 0.7 MPa operating pressure, this 200 mm bore cylinder generates 21991 N of push force and 15080 N of pull force. At the maximum operating pressure of 1.0 MPa, it can deliver up to 15708 N of push force.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 290 mm nominal stroke by up to 30 mm, providing a usable travel window of 260-290 mm. This stopper only sets the end position; it does not lock or hold the load without continuous air pressure.
