About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX800-100
The AirTAC SAIJ200X800-100 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust for heavy-duty automation. It yields 15708N push and 15080N pull force at 0.5 MPa, peaking at 3204 kgf at 1.0 MPa. A 100mm adjusting screw lets you dial the effective travel back from its 800mm nominal length, creating a precise 700-800mm usable window for product changeovers without external stops.
This unit features a SUS420J2 stainless steel rod (option A) for superior corrosion resistance and carries PT tapered port threads (G3/4). The extruded aluminum barrel includes sensor grooves on both sides. Note the rear stopper only sets the end position; it is not a lock and cannot hold loads without live air.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX800-100 Is Used
Heavy Press Tuning
Dial in the exact 700-800mm end position during machine setup to accommodate different die heights without adding external mechanical stops.
Large Product Changeover
Adjust the retract distance on the fly for packaging lines handling oversized pallets or varied product lengths.
High-Force Positioning
Leverage 15708N of push force at 0.5MPa to move heavy assemblies, using the 100mm trim window to perfect the final resting point.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX800-100 the Right Cylinder?
Select this 200mm bore when 160mm (10053N at 0.5MPa) lacks the necessary push force for large presses or heavy material handling. The adjustable 700-800mm window is perfect for lines running varied product sizes, letting you fine-tune the retract end at commissioning rather than swapping cylinders. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
Because the 800mm stroke is long, the 40mm rod needs external guidance to prevent excessive side-loading, even with the robust M36x2 thread. The rear adjuster acts purely as a travel stop, not a brake; for load-holding without air pressure, specify an external rod lock or choose a SAIL or BSAI cylinder.
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 SAIJ200AX800-100 FAQ
At 0.5 MPa it provides 15708N push and 15080N pull force. At its maximum 1.0 MPa operating pressure, it delivers a peak push force of 3204 kgf.
The rear adjuster screw allows you to shorten the 800mm nominal stroke by up to 100mm, providing a usable travel window of 700-800mm. This stopper sets the end position but does not lock the load without live air pressure.
