About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX550-10
The AirTAC SAIJ200X550-10 is a double-acting ISO 15552 profile cylinder equipped with a rear mechanical stopper, allowing you to fine-tune the end-of-stroke position during commissioning. This SKU provides a usable travel window of 540-550mm, trimming the nominal 550mm stroke by up to 10mm without adding external stops. It delivers robust thrust, pushing 15708N and pulling 15080N at 0.5 MPa, making it ideal for heavy-duty manipulation.
Built with an SUS420J2 stainless steel rod (option A) and PT tapered port threads, this 200mm bore actuator handles demanding environments. The extruded aluminum barrel includes sensor grooves on both sides for mounting CMSE reed or DMSE electronic switches if position feedback is later required. The rear adjuster acts purely as a travel stop to set deceleration and end-position, not as a load-holding lock.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX550-10 Is Used
Heavy Press Tuning
Dial in the exact 540-550mm contact position for heavy pressing operations, ensuring precise force application without mechanical shims.
Assembly Line Changeover
Adapt the end-stop quickly during product size changeovers on automated lines, saving downtime by adjusting the rear screw instead of replacing the cylinder.
Large Material Positioning
Index heavy structural materials or large components into a workstation, relying on the 15708N push force and fine-tuned end-position stop.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX550-10 the Right Cylinder?
Select this 200mm bore cylinder when an application requires extreme force—up to 15708N push at 0.5 MPa—and a precise 540-550mm travel window. The adjustable stroke is chosen over a fixed SAI when you need to dial in the exact end-position during machine setup or product changeover without swapping out the actuator. For context, dropping to a 160mm bore yields 10053N push force, while staying at 200mm maximizes output.
Because the 550mm stroke is substantial, the 40mm rod and M36x2 thread provide rigidity, but an external guide is still recommended to prevent excessive side loading on long unsupported travels. The mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2. If the machine requires holding the load without live air pressure, the SAIJ adjuster cannot perform this; you must specify a SAIL pneumatic lock, BSAI clamp-lock, or an external rod lock instead. It is dimensionally interchangeable per ISO 15552.

- ✓ 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 SAIJ200AX550-10 FAQ
At 0.5 MPa operating pressure, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 3204 kgf.
The rear adjuster acts as a mechanical stop that lets you shorten the effective stroke from 550mm down to 540mm. It is used for fine-tuning the end position at commissioning; it does not lock or hold the load without continuous air pressure.
