About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX750-30S
The AirTAC SAIJ200X750-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 750 mm travel by up to 30 mm. This yields a usable 720-750 mm end-position window for precise machine setup without adding external stops. As the largest bore in the series, it delivers immense thrust, pushing with 21991 N and pulling with 15080 N at 0.7 MPa. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches.
This variant ships with an SUS420J2 stainless steel piston rod (code A) for superior corrosion resistance compared to standard carbon steel. It features PT tapered port threads and a built-in magnet for position sensing. The rear adjuster functions strictly as a mechanical stop to decelerate and set the travel end; it does not lock the load. For fail-safe load holding without live air pressure, you must use an external rod lock or a related AirTAC type like SAIL or BSAI.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX750-30S Is Used
Heavy Pressing Calibration
Dial in the exact 720-750 mm travel window during setup to ensure massive 21991 N pressing forces are applied accurately without machine frame deflection.
Large Package Diversion
Adjust the retract stopper on the fly to handle varying oversized pallet sizes on a packaging line without swapping out the entire actuator.
Automated Assembly Stations
Use the fine-tune rear screw to set precise end-of-stroke positions for heavy component seating, relying on the robust SUS420J2 rod for durability.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX750-30S the Right Cylinder?
Selecting this 200 mm bore cylinder is appropriate when your application requires maximum force, as it delivers 15708 N of push force even at a low 0.5 MPa. If your force requirements are lower, stepping down to a 160 mm bore provides 10053 N at 0.5 MPa, which might better suit medium-heavy loads while saving space. The adjustable stroke is chosen over a fixed SAI cylinder when you need fine end-position tuning during commissioning or frequent product-size changeovers on a packaging line.
Because this model features a 750 mm stroke, the 40 mm diameter rod and M36x2 thread are substantial but still require an external guide to prevent excessive side-loading on the long unsupported travel. When replacing an ISO 15552 cylinder, match the 200 mm bore, 750 mm stroke, 30 mm adjustment, PT G3/4 ports, and the -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, explicitly omitting FB, CA, CB, and CR brackets.

- ✓ 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 SAIJ200AX750-30S FAQ
The rear adjuster acts as an external stopper that lets you shorten the effective travel by up to 30 mm, providing a 720-750 mm usable window. It only sets the travel end and decelerates the load; it does not function as a lock or brake to hold the load without live air pressure.
At an operating pressure of 0.7 MPa, this double-acting cylinder generates 21991 N of push force and 15080 N of pull force. It can deliver a maximum push force of 28274 N at 0.9 MPa.
