About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX180-40S
The AirTAC SAIJ200X180-40-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a substantial 15708N push force at 0.5MPa and features a 40mm adjustment range, creating a 140-180mm usable travel window for precise end-position tuning. The SUS420J2 stainless steel rod (code A) offers high corrosion resistance, while the integrated magnet (-S) enables direct positioning feedback.
This model utilizes a PT tapered port and includes variable air cushions at both ends to manage high kinetic energy. The rear screw acts purely as a mechanical stop to dial in the stroke during commissioning; it does not lock or hold the load without continuous live air pressure. For load-holding requirements, an external SAIL or BSAI locking cylinder is required.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX180-40S Is Used
Heavy Machinery Setup
Fine-tunes the retraction end-stop during heavy machinery commissioning, allowing operators to dial in the 140-180mm travel window without installing external mechanical stops.
Variable Product Forming
Accommodates different material thicknesses on a high-force press line by adjusting the stroke up to 40mm on the fly, ensuring precise positioning without cylinder replacement.
Automated Clamping Stations
Delivers up to 3204kgf clamping force while permitting rapid changeover between fixture sizes, utilizing the rear adjuster to set the exact clamping depth.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX180-40S the Right Cylinder?
Select this 200mm bore cylinder when an application demands extreme thrust alongside variable end-stops, such as accommodating product size changes on a line without swapping hardware. If 15708N at 0.5MPa exceeds your requirements, stepping down to a 160mm bore yields 10053N, whereas this 200mm unit maxes out at 3204kgf at 1.0MPa. The adjustable rear stopper allows for on-the-fly fine-tuning that a fixed-stroke SAI cylinder cannot provide.
When integrating this ISO 15552 interchangeable profile cylinder, verify your setup matches the exact configuration: 200mm bore, 180mm stroke, 40mm adjustment, PT port thread, and a -S magnet for CMSE reed or DMSE electronic sensors. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the 180mm stroke is relatively short for this massive bore, standard side-load risks are minimized, but external guides remain recommended for optimal rod bearing life.
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 SAIJ200AX180-40S FAQ
At 0.5MPa operating pressure, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. At its maximum rated pressure of 1.0MPa, it delivers a peak push force of 3204kgf.
The rear adjuster screw allows you to shorten the nominal 180mm stroke by up to 40mm, providing a usable travel window of 140-180mm. This stopper fine-tunes the end position but does not hold the load without live air pressure.
