About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX325-100S
The AirTAC SAIJ200X325-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a substantial 15708N of push force at 0.5 MPa and features a usable travel window from 225 to 325 mm, letting you dial back the nominal stroke by up to 100 mm. This specific SKU includes a SUS304 stainless steel rod for superior corrosion resistance and a built-in magnet for CMSE reed and DMSE electronic sensors.
Because the massive 40 mm rod and M36x2 thread handle extreme loads, this 200 mm bore profile cylinder manages heavy dynamics well. The rear adjuster acts purely as a mechanical stop to fine-tune the retract end position during commissioning; it does not lock or hold the load without live air. For load-holding requirements, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX325-100S Is Used
Heavy Pressing Operations
Dial in the exact 225-325mm travel window for high-force pressing tasks, ensuring perfect material displacement during product changeovers.
Automated Assembly Lines
Fine-tune the retract end-stop during commissioning to accommodate varying part sizes without physically replacing the cylinder or adding external stops.
Large Material Handling
Use the robust 40mm stainless steel rod to move heavy workpieces, adjusting the stroke on the fly to align with different conveyor widths.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX325-100S the Right Cylinder?
Choose this 200 mm bore adjustable cylinder when your application requires precise end-position tuning during machine setup or product changeover without swapping out physical components. If your process needs less force, stepping down to a 160 mm bore yields 10053N of push force at 0.5 MPa. If you need maximum thrust, this 200 mm bore is the largest standard option, delivering up to 3204 kgf at 1.0 MPa.
Since the 325 mm stroke exceeds the 300 mm threshold, an external guide rail is recommended to prevent excessive side-loading on the rod. To replace an ISO 15552 cylinder, match the 200 mm bore, 325 mm stroke, PT tapered port, and the -S magnet requirement. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets.
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 SAIJ200BX325-100S FAQ
At an operating pressure of 0.5 MPa, this 200 mm bore cylinder delivers 15708N of push force and 15080N of pull force. At the maximum 1.0 MPa pressure, it achieves 3204 kgf.
The rear mechanical adjuster allows you to shorten the effective travel from the nominal 325 mm down to 225 mm, creating a 100 mm tuning window. It functions as a travel stop and does not hold the load without live air pressure.
