About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX30-10S
The AirTAC SAIJ200X30-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling a usable travel window of 20 to 30 mm. Delivering 15708 N of thrust at 0.5 MPa, this massive 200 mm bore unit handles heavy-duty positioning. It features a SUS420J2 stainless steel rod for enhanced corrosion resistance and a PT tapered port thread.
Because the rear adjuster acts solely as a mechanical stop to fine-tune the retract position, it does not lock the load without live air pressure. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated magnet supports AirTAC CMSE reed and DMSE electronic switches for precise end-of-travel detection.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX30-10S Is Used
Heavy Machinery Changeover
Dial in the 20-30 mm travel window during heavy equipment product line changeovers without swapping out the entire cylinder.
Variable End Stops
Set precise retract end positions for heavy pressing or lifting applications, tuning the exact stopping point at commissioning.
Assembly Positioning
Use the massive 15708 N push force to move heavy assemblies, adjusting the stroke by up to 10 mm to perfect the contact point.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX30-10S the Right Cylinder?
Choose this 200 mm bore cylinder when a fixed 30 mm stroke is insufficient for your machine setup, requiring a 20-30 mm adjustable window for product changeovers. If you need less force, stepping down to a 160 mm bore yields 10053 N at 0.5 MPa, whereas moving up is impossible within standard SAIJ limits. For applications requiring position holding without continuous air supply, consider the SAIL or BSAI series, as this standard adjuster only halts travel.
To match this ISO 15552 interchangeable profile cylinder, specify a 200 mm bore, 30 mm nominal stroke, 10 mm adjustment, PT ports, Basic/FA/LB/TC/FTC/TCM1/TCM2 mountings, and an -S magnet. The 20 mm piston rod and M36x2 thread provide high rigidity, though long unsupported strokes still require an external guide.
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 SAIJ200AX30-10S FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. It can reach a maximum push force of 21991 N at 0.7 MPa.
The rear adjuster screw allows you to mechanically shorten the nominal 30 mm stroke, providing an adjustable travel window of 20 to 30 mm. This stopper fine-tunes the end position but does not hold the load without live air pressure.
