About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX260-40
The AirTAC SAIJ200X260-40 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the effective travel anywhere within a 220-260 mm window. Utilizing a robust 200 mm bore, it delivers 15708 N of push force and 15080 N of pull force at 0.5 MPa, making it suitable for heavy-duty positioning tasks. The extruded aluminum barrel features sensor grooves on both sides for flexible switch placement.
This specific configuration incorporates an SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance, paired with PT tapered port threads. The rear stopper mechanism lets you dial in the exact end position during commissioning without adding external stops, while the standard air cushions handle deceleration at both ends.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX260-40 Is Used
Heavy Machinery Setup
Dial in the exact 220-260 mm end position during heavy machinery commissioning without machining custom external stopper blocks.
Product Line Changeover
Quickly adjust the stroke length by up to 40 mm when switching between different product sizes on a high-force assembly line.
Large Press Positioning
Fine-tune the retraction point of a 15708 N press motion to accommodate varying material thicknesses on the fly.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX260-40 the Right Cylinder?
Choose this 200 mm bore model when your application requires substantial thrust, such as 15708 N at 0.5 MPa, but demands precise end-position tuning over a 220-260 mm travel path. If your force requirements are lower, stepping down to a 160 mm bore yields 10053 N of push force at 0.5 MPa, whereas keeping the 200 mm bore provides maximum rigidity. The adjustable stroke is ideal for product changeovers on a line, allowing quick modifications without swapping the cylinder.
For a seamless ISO 15552 replacement match, verify the 200 mm bore, 260 mm nominal stroke, 40 mm adjustment range, PT port threads, and standard mounting configuration. Note that the rear adjuster acts strictly as a travel stop and does not hold the load without live air; for positive load-holding, consider an AirTAC SAIL or BSAI cylinder. Because the stroke is 260 mm, ensure adequate external guiding to prevent excessive side-loading on the rod.
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 SAIJ200AX260-40 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 achieves up to 3204 kgf.
The rear adjuster screw allows you to shorten the 260 mm nominal stroke by up to 40 mm, providing a usable travel window of 220 to 260 mm. This stopper fine-tunes the end position but does not lock the load without continuous air pressure.
