About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX155-100
The AirTAC SAIJ200X155-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers massive thrust, generating 15080N of pull force at 0.5 MPa and up to 28274N at 0.9 MPa. The built-in stopper screw trims the nominal 155mm stroke, providing a precise 55-155mm usable travel window for product changeovers without adding external stops.
This heavy-duty unit uses an SUS420J2 stainless steel rod for enhanced durability against lateral stress. It includes variable air cushions at both ends to decelerate the large 3204kgf max load. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air pressure; for true load-holding, consider the SAIL or BSAI series.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX155-100 Is Used
Heavy Press Tuning
Dial in the exact 55-155mm end position during press commissioning to accommodate varying material thicknesses without swapping cylinders.
Product Size Changeover
Quickly adjust the travel window on automated heavy assembly lines when switching between different product dimensions.
Large Load Positioning
Move and position massive components using up to 28274N of thrust, relying on the rear stopper to set the precise retract distance.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX155-100 the Right Cylinder?
Choose this 200mm bore cylinder when your application requires extreme force and a variable end-stop. If your setup needs less thrust, stepping down to a 160mm bore yields 9425N pull at 0.5 MPa, whereas this 200mm bore provides 15080N. The 100mm adjustment range is perfect for commissioning fine-tuning on the fly, differing from a fixed-stroke SAI cylinder by allowing rapid machine setup changes.
As a dimensionally interchangeable ISO 15552 profile cylinder, it matches standard mounting footprints using a PT tapered port thread. It supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, deliberately omitting FB, CA, CB, and CR options. Because it lacks a -S magnet, it will not work with CMSE or DMSE sensors without modification. If you need to hold a load safely without continuous air, use an external rod lock.
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 SAIJ200AX155-100 FAQ
At a 0.5 MPa operating pressure, it provides 15708N of push force and 15080N of pull force. At 0.9 MPa, the push force increases to 28274N.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective travel from the nominal 155mm down to 55mm. It sets the end position but does not lock the load without live air pressure.
