About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX225-100
The AirTAC SAIJ200X225-100 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications, delivering a substantial 15708 N push force at 0.5 MPa. It features a robust 40 mm carbon steel rod and PT tapered G3/4 ports to handle high flow demands. By integrating a rear stroke adjuster, this model provides a usable travel window of 125 to 225 mm, allowing you to dial in the exact end position without swapping out the entire unit.
This adjustable-stroke design is tailored for commissioning flexibility and product changeovers, utilizing a rear stopper screw rather than external stops. The extruded aluminum barrel includes sensor grooves on both sides, and while this specific SKU omits the magnet, the SUS420J2 (A) stainless steel rod option provides excellent corrosion resistance. The adjuster acts purely as a travel stop to set deceleration alongside the variable air cushions, meaning it will not hold a load without continuous live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX225-100 Is Used
Heavy Press Tuning
Fine-tune the pressing depth of massive 15708 N loads during setup, using the 125-225 mm window to perfectly calibrate end positions without external stopper hardware.
Product Changeover
Adapt a heavy-duty transfer line to new pallet sizes instantly by dialing back the stroke up to 100 mm, reducing downtime compared to physically swapping cylinders.
Large Assembly Jigs
Secure and position large components on assembly jigs, relying on the 40 mm SUS420J2 stainless rod to resist side loads and corrosion in industrial environments.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX225-100 the Right Cylinder?
Selecting this 200 mm bore cylinder makes sense when your application requires extreme thrust—up to 15708 N push at 0.5 MPa—and on-the-fly end-position tuning across a 125-225 mm window. If your force requirements are lower, stepping down to a 160 mm bore yields 10053 N of push force, but the SAIJ200X225-100 is unmatched for massive loads. Because the nominal stroke is 225 mm, you avoid the need for complex external guides, though the 40 mm rod and M36x2 thread inherently handle significant side loads. To match this ISO 15552 dimensionally interchangeable cylinder, confirm the 200 mm bore, 225 mm stroke, 100 mm adjustment, PT G3/4 port, and the SUS420J2 rod material.
Remember that the rear adjuster is a stop, not a locking mechanism; it cannot hold a load without live air. For true load-holding capabilities without continuous pressure, consider an AirTAC SAIL pneumatic lock, a BSAI clamp-lock cylinder, or an external rod lock. This model supports mounting options including Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR configurations.

- ✓ 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 SAIJ200AX225-100 FAQ
At a 0.5 MPa operating pressure, this 200 mm bore cylinder generates a push force of 15708 N and a pull force of 15080 N. At the maximum 1.0 MPa pressure, it can deliver up to 3204 kgf.
The rear adjuster screw allows you to shorten the effective travel from the 225 mm nominal stroke down to as little as 125 mm. This creates a 125-225 mm adjustable window for fine-tuning the retract end position at commissioning, but it functions only as a stop and does not lock the load without live air.
