About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX270-100S
The AirTAC SAIJ200X270-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 170-270 mm usable travel window, allowing you to dial back the nominal 270 mm stroke by up to 100 mm during commissioning. This bore generates 15708 N of push force at 0.5 MPa and reaches 28274 N at 0.9 MPa, making it a robust choice for heavy-duty positioning.
This variant features a SUS420J2 stainless steel rod (code A) and includes a magnet for CMSE reed and DMSE electronic sensors. The G3/4 PT tapered ports and 50 mm cushions manage high airflow and deceleration. The rear adjuster acts purely as a mechanical stop to set the end position; it does not hold the load without live air, so consider a SAIL or BSAI lock for fail-safe holding.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX270-100S Is Used
Heavy Press Tuning
Dial in the exact 170-270 mm end-position for large assembly presses without machining new external stopper blocks.
Pallet Changeover
Adjust the retract distance on the fly to accommodate different pallet sizes on a high-thrust transfer line.
Automated Forming
Set precise bottoming positions for heavy metal-forming operations, leveraging the 28274 N push force at 0.9 MPa.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX270-100S the Right Cylinder?
Select this 200 mm bore when your application requires the 15708 N push force at 0.5 MPa, which is a substantial step up from the 100 mm bore that yields 3927 N. An adjustable stroke is ideal here if you need variable end-stops for product changeovers without physically swapping the cylinder or adding external stopper blocks.
For an ISO 15552 replacement, match the 200 mm bore, 270 mm stroke, 100 mm adjustment range, G3/4 PT ports, and the -S magnet requirement. Because the stroke is 270 mm, ensure your mounting setup provides adequate external guidance to prevent excessive side-loading on the large 40 mm rod. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.
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 SAIJ200AX270-100S FAQ
At 0.5 MPa it provides 15708 N of push force and 15080 N of pull force. At 0.9 MPa, the push force increases to 28274 N.
The rear adjuster screw lets you mechanically shorten the stroke from 270 mm down to 170 mm. This stopper only sets the travel end and does not lock the load without live air pressure.
