About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX90-10S
The AirTAC SAIJ200X90-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a substantial 15708N of thrust at 0.5 MPa while featuring a 10mm adjustment range that creates an 80-90mm usable travel window. This built-in rear stopper allows you to fine-tune the retract end position at commissioning without adding external physical stops or changing the cylinder itself.
This 200mm bore unit incorporates a SUS420J2 stainless steel rod for superior corrosion resistance and includes a magnet for use with AirTAC CMSE reed and DMSE electronic sensors. It utilizes a PT tapered G3/4 port and operates at speeds of 30-500mm/s. The extruded aluminum barrel includes sensor grooves on both sides, and the unit supports a specific mounting subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX90-10S Is Used
Heavy Press Tuning
Dial in the exact 80-90mm retract stop on heavy assembly presses during initial commissioning to accommodate varying material thicknesses without external stop blocks.
Product Changeover
Quickly adjust the retract end-position by up to 10mm on automated packaging lines when switching to a different product size, minimizing machine downtime.
Position Sensing Setup
Leverage the built-in magnet and dual sensor grooves to mount CMSE or DMSE switches precisely alongside the adjusted travel window for reliable end-of-stroke detection.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX90-10S the Right Cylinder?
Select this 200mm bore model when an application requires heavy thrust combined with precise end-position tuning, as the 10mm rear adjuster allows exact retract positioning without swapping cylinders during product changeovers. If your process demands less force, stepping down to a 160mm bore yields 10053N of push force at 0.5 MPa, which may be sufficient for lighter loads. Conversely, if you need fixed standard travel without the adjuster screw, the standard SAI series is the direct alternative.
When integrating this cylinder, note that the rear adjuster acts solely as a travel stop to decelerate the stroke, not as a locking device. A plain SAIJ cannot hold a load without live air pressure; for true fail-safe load holding, consider the SAIL or BSAI series instead. For ISO 15552 replacement matching, confirm the 200mm bore, 90mm stroke, 10mm adjustment, PT G3/4 port, required mounting style, and the -S magnet option.

- ✓ 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 SAIJ200AX90-10S FAQ
At 0.5 MPa operating pressure, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. At its maximum rated pressure of 1.0 MPa, it can deliver up to 3204 kgf of thrust.
The rear external adjuster screw allows you to shorten the nominal 90mm stroke by up to 10mm, creating an 80-90mm usable travel window. This stopper decelerates the travel end for fine-tuning during setup but does not lock or hold the load without continuous air pressure.
