About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX900-20S
The AirTAC SAIJ200X900-20-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a robust 15708N push force at 0.5MPa and a usable travel window of 880-900mm, letting you fine-tune the retract end-position without adding external stops. This unit includes a SUS420J2 stainless steel rod and a magnet for CMSE or DMSE sensors.
Equipped with PT tapered ports and a G3/4 connection, it handles heavy loads up to 3204kgf at 1.0MPa. The rear adjuster acts purely as a mechanical stop to set the travel end and does not hold the load without live air. For position holding, consider SAIL or BSAI models.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX900-20S Is Used
Heavy Press Tuning
Dial in the exact 880-900mm end-stop during commissioning for large assembly presses without machining external stopper blocks.
Product Changeover
Quickly adjust the retract position on automated lines when shifting between product variants requiring slightly different stroke lengths.
Long-Stroke Alignment
Fine-tune the end position of heavy 900mm travel actuators to align large fixtures perfectly without swapping the cylinder.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX900-20S the Right Cylinder?
Choose this 200mm bore when 160mm falls short at 10053N push, or step down if 125mm at 6136N is sufficient. An adjustable stroke is ideal for machine setup and product changeover, allowing you to dial in the exact 880-900mm travel during commissioning rather than swapping a fixed-stroke SAI cylinder. To match this ISO 15552 footprint, specify 200mm bore, 900mm stroke, 20mm adjustment, PT ports, and the -S magnet.
With a 900mm stroke, the 40mm rod diameter and M36x2 thread provide rigidity, but an external guide is recommended to manage side loads on long unsupported travel. The mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ200AX900-20S FAQ
At 0.5MPa operating pressure, it provides 15708N of push force and 15080N of pull force. At the maximum 1.0MPa pressure, it delivers up to 3204kgf.
The rear adjuster screw lets you shorten the nominal 900mm stroke by up to 20mm, creating an 880-900mm travel window. It functions as a mechanical stop and does not lock the load without live air pressure.
