About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX270-40S
The AirTAC SAIJ200X270-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 270 mm travel by up to 40 mm. This creates a precise 230-270 mm usable window for fine-tuning end positions at commissioning without swapping hardware. It features a SUS420J2 stainless steel rod (option A) and a PT tapered port thread, built to handle massive thrust up to 15708 N at 0.5 MPa or 3204 kgf at 1.0 MPa.
The 40 mm diameter piston rod and M36x2 thread provide exceptional rigidity, while the extruded aluminum barrel integrates sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches. The rear adjuster acts purely as a mechanical stop to set deceleration alongside the variable air cushions, meaning it cannot hold a load without live air pressure. For load-holding requirements, explore the SAIL or BSAI series.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX270-40S Is Used
Heavy Press Tuning
Dial in the exact 230-270 mm end position during machine setup to accommodate varying material thicknesses in large stamping or pressing operations.
Product Changeover
Quickly adjust the retract stop by up to 40 mm when switching product sizes on a high-force assembly line without replacing the cylinder.
Large Assembly Stops
Use the mechanical rear stopper to set precise deceleration points for heavy 3204 kgf loads where standard fixed-stroke cylinders lack flexibility.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX270-40S the Right Cylinder?
Choose this 200 mm bore when your application requires extreme force, stepping up from the 160 mm bore which provides 10053 N at 0.5 MPa. The adjustable stroke is ideal for product changeovers on large machinery, allowing operators to set variable end-stops on the fly. When replacing an ISO 15552 cylinder, match the 200 mm bore, 270 mm nominal stroke, 40 mm adjustment, PT port thread, and the -S magnet. For any stroke of 300 mm or more, external guides are recommended to prevent side-loading, though this 270 mm travel benefits from the robust 40 mm rod. Remember that 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 SAIJ200AX270-40S 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 delivers up to 3204 kgf.
The rear adjuster screw lets you shorten the 270 mm nominal stroke by up to 40 mm, creating a 230-270 mm travel window. It functions as a mechanical stop to tune the end position and does not lock the load without live air.
