About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX110-40
The AirTAC SAIJ200X110-40 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust for heavy-duty positioning. It provides a usable travel window of 70 to 110 mm, allowing you to dial back the nominal 110 mm stroke by up to 40 mm during commissioning. At 0.5 MPa, it generates 15708 N of push force and 15080 N of pull force.
This specific configuration features a SUS420J2 stainless steel rod for enhanced corrosion resistance and PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. It operates at speeds of 30-500 mm/s and relies on adjustable air cushions at both ends to decelerate the load.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX110-40 Is Used
Heavy Press Tuning
Fine-tune the 70-110 mm stroke end-stop precisely during heavy press commissioning to avoid over-travel damage.
Product Size Changeover
Quickly adjust the retract position to accommodate varying package sizes on a high-thrust conveyor diverter line.
Variable End Stops
Use the 40 mm adjustment window to set multiple physical end positions for different heavy-duty machine setups.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX110-40 the Right Cylinder?
Choose this 200 mm bore size when your application demands up to 15708 N of push force at 0.5 MPa, stepping up from a 160 mm bore that yields 10053 N. The adjustable stroke is ideal for machinery requiring frequent product-size changeovers, as the rear stopper fine-tunes the end position without swapping cylinders or adding external stops. Remember that the rear adjuster acts only as a travel stop, not a lock; it will not hold the load without live air pressure. For fail-safe load holding, consider an external rod lock or the AirTAC SAIL series.
When replacing an ISO 15552 cylinder, match the 200 mm bore, 110 mm stroke, 40 mm adjustment range, PT port threads, and the SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the stroke is 110 mm, side-load risks are moderate, but you should still ensure proper guide support for the 40 mm diameter rod to prevent premature seal wear.
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 SAIJ200AX110-40 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 can deliver up to 3204 kgf.
The rear adjuster allows you to shorten the effective travel from the 110 mm nominal stroke down to a minimum of 70 mm, creating a 70-110 mm usable window. The adjuster acts as a physical stop to set the retract end position and does not lock the load without live air.
