About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX240-40
The AirTAC SAIJ200X240-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 200-240 mm usable travel window. Built with a SUS420J2 stainless steel rod, it handles massive loads, delivering 15708 N of push force and 15080 N of pull force at 0.5 MPa. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE or DMSE switches.
This model uses PT tapered port threads (G3/4) and achieves a standard speed range of 30-500 mm/s. The rear adjustment screw acts purely as a travel stop to fine-tune the retract end position during commissioning. It does not lock the load without live air pressure; for fail-safe holding, consider the SAIL or BSAI series.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX240-40 Is Used
Heavy Press Toning
Dial in the exact 200-240mm travel window during machine setup to apply precise 15708N clamping force without over-traveling the press bed.
Product Changeover
Adjust the retract stop on the fly when switching to different package sizes on a heavy-duty packaging line, avoiding mechanical rebuilds.
Large Assembly Jigs
Use the rear stopper to fine-tune the end position of a 240mm stroke during initial commissioning of large automotive or industrial assembly fixtures.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX240-40 the Right Cylinder?
Choose this 200 mm bore when your application requires maximum thrust, stepping up from a 160 mm bore that provides 10053 N at 0.5 MPa. The 40 mm adjustment range is ideal for product-size changeovers, allowing you to dial back the 240 mm nominal stroke to a precise 200 mm without adding external stops or swapping the cylinder.
When replacing an ISO 15552 cylinder, match the 200 mm bore, 240 mm stroke, PT G3/4 port, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the stroke is 240 mm, ensure external guides support the 40 mm rod to prevent excessive side-loading on the piston.
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 SAIJ200AX240-40 FAQ
At 0.5 MPa it provides 15708 N of push force and 15080 N of pull force. At the maximum 1.0 MPa operating pressure, it delivers up to 3204 kgf.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 240mm nominal stroke by up to 40mm. This creates a 200-240mm usable travel window for fine-tuning the end position without replacing the cylinder.
