About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX180-100
The AirTAC SAIJ200X180-100 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications requiring exact end-position tuning. It delivers 15708 N of push force at 0.5 MPa and features a 100 mm rear stroke adjuster, creating a usable travel window of 80 to 180 mm. This built-in adjustability allows operators to dial in the exact retract distance during commissioning without adding external stops.
This model is equipped with a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and features PT tapered port threads. It supports an operating speed of 30-500 mm/s and utilizes variable air cushions at both ends to decelerate massive loads smoothly. The rear stopper mechanism sets the travel limit but does not lock the load; for position holding without live air pressure, an external rod lock or a SAIL pneumatic locking cylinder is required.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX180-100 Is Used
Heavy Press Tuning
Fine-tune the retract distance of high-tonnage pressing operations within the 80-180 mm window to accommodate different material thicknesses without swapping cylinders.
Product Changeovers
Rapidly adjust the end-stop position on heavy packaging or material handling lines to process varying pallet sizes on the fly.
Machine Setup Calibration
Dial in the exact end position during initial commissioning to prevent crashes, using the rear stopper to set precise physical limits for massive loads.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX180-100 the Right Cylinder?
Selecting the SAIJ200X180-100 is ideal when a 180 mm nominal stroke needs frequent trimming to accommodate varying product sizes on a line, offering an 80 to 180 mm adjustment window. If your application exceeds the 15708 N push force at 0.5 MPa, you must step up to external boosters, as 200 mm is the largest standard ISO 15552 bore. Conversely, if your load requirements are lower, a 160 mm bore provides 10053 N of push force at 0.5 MPa and might be a lighter, more economical choice.
When integrating this cylinder, note that its 180 mm stroke falls below the 300 mm threshold requiring external side-load guidance, but the substantial 40 mm rod diameter handles high bending stresses well. This adjustable version uses a reduced mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. It is dimensionally interchangeable per ISO 15552, uses PT ports, and because no magnet is specified, it will not work with CMSE or DMSE sensors without modification.

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 SAIJ200AX180-100 FAQ
At an operating pressure of 0.5 MPa, this 200 mm bore cylinder provides a push force of 15708 N and a pull force of 15080 N. At the maximum rated pressure of 1.0 MPa, it can deliver up to 3204 kgf of push force.
The rear adjuster acts as a mechanical stop, allowing you to shorten the effective stroke from its 180 mm nominal length down to as little as 80 mm. This creates an 80-180 mm adjustable travel window for fine-tuning at commissioning, though it does not lock the load without continuous air pressure.
