About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX225-10
The AirTAC SAIJ200X225-10 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications. It features an external rear adjusting screw that permits you to trim the effective stroke by up to 10 mm, creating a precise 215-225 mm usable travel window for exact commissioning. Delivering immense thrust, it provides 21991 N of push force at 0.7 MPa and 28274 N at 0.9 MPa.
This variant incorporates a SUS420J2 stainless steel rod for enhanced corrosion resistance and utilizes PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, though this specific configuration omits the internal magnet. The rear adjuster functions purely as a travel stop to fine-tune the end position, meaning it will not hold a load dynamically without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX225-10 Is Used
Heavy Press Tuning
Dial in the exact end-stop on heavy stamping or press lines to compensate for material thickness variance without changing the cylinder.
Assembly Line Changeover
Quickly adjust the 215-225 mm travel window during product size changeovers to accommodate new part dimensions on the fly.
Large Clamp Positioning
Fine-tune the clamping reach on large fabricated parts, ensuring precise alignment before the final high-force lock.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX225-10 the Right Cylinder?
Selecting this 200 mm bore model is ideal when your machinery demands exceptionally high force that smaller bores cannot supply, such as stepping up from a 160 mm bore that offers 14074 N push at 0.7 MPa. The 10 mm adjustable range is chosen when you need minor end-position tuning during machine setup or product changeover, avoiding the need to swap out the entire cylinder or bolt on external stops. For load-holding requirements without continuous air pressure, this cylinder is insufficient; you should consider the SAIL or BSAI series instead.
Because this SKU features a 225 mm stroke, it remains within the 1500 mm standard maximum for this bore, keeping it a standard catalog item. When integrating this cylinder, ensure your mounting choice comes from the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, or TCM2, as FB, CA, CB, and CR configurations are omitted. The robust 40 mm rod diameter and M36x2 thread handle significant side loads, though any long unsupported stroke still necessitates an external guide.
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 SAIJ200AX225-10 FAQ
At an operating pressure of 0.7 MPa, this 200 mm bore cylinder generates 21991 N of push force and 15080 N of pull force. At 0.9 MPa, the push force increases to 28274 N.
The rear adjuster screw acts as a mechanical stop that allows you to shorten the nominal 225 mm stroke by up to 10 mm, providing a usable travel window of 215-225 mm. It only sets the end position and does not lock the load without live air pressure.
